l) The EPIC System Overview
The EPIC (Electron Photon Interaction Code) system includes not only
data t'or electrons and photons, but also data I'or positrons, light
charged particles (proton, deuteron, triton, helium-3 and alpha)
and neutrons. All o1' these data libraries are maintained in a sitnple,
standard tabular character based t'orlnat, SO they can be easily moved
to any computer. Once they have been lnoved to any computer they are
converted to binary, random access tiles, using standard FORTRAN, so
that they can be quickly and et'ficietltly accessed ()!1 thal computer.
2) Tile Epicshow code
Epicshow is tile part of tile EPIC systenl'that allows viewers to access
and interact with tile EPIC data bases. This code call be used l'_r a
variely of purposes. At the most basic level this code is all interactive
J "replacement for our [ CRL-50400 series publications on photon, electron
and neutron data. The EPIC libraries contain all of the data presented
in these publications, and by using Epicshow you can not only view the
data as presented in these publications_ you can also interact with the
data, e.g., zoom ill to examine any energy range in more detail, compare
data t_)r different target materials or projectiles side by side. At a
more sophisticated level it call be used to compare the data libraries
and the results of EPIC transport calculations, in order to better
understand tile elTects observed ill tile results o1' calculations.
3) Contents of the Data Bases
Each data base is t'or a given type of projectile: photon,s, electrons,
positrons, charged particles and neutrons. Each data base contains
data l_)r a variety of targets, either elemental or isotopic.
The EPIC data bases include data fl_r elements hydrogen (Z=I) through
fermium (Z=I00) over the energy range 10 eV to 1 Gev for photons,
electrons, positrons and light charged particles (protons, deuterons,
tritons, helium-3 and all)ha particles). EPIC uses analytical expressions
to extend this data to higher energies. The EPIC neutron data base
includes data for elements and isotopes over the energy range
-4-
1.0e-04 eV to 2(t MeV, with provisions to incorporate higher energy
data as il becomes available. See lhe EPI( _,reporl for a description
o1"the sources o1' this dala.
in lhis report I ret'er I_ l.vpes _1'dala as tn_tior, tnilmr, deposition,
range and slraggling. Major and minor rel'er Io phololl, eleclron,
positron and neutron cross sections; no cross sections are included
for charged particles. For photons major cross sections include total,
photoelectric, coherent, incoherenl, pair and triplet cross sections.
For electrons major cross seclions include total, ionization,
l_remsstrahlung, e×citation, elas|ic and elastic Iransporl cross
sections. For photons and electrons minor cross sections are the
photoelectric and ionization subsheil cross sections, respectively,
For neutrons major cross sections include total, elastic, capture,
fission and total inelastic cross sections. Minor cross sections
include inelastic level, (n,2n), etc.
Energy deposition data is included for all pro.iectiles in the I'orm
ot' MeV lost pet"collision (microsc()l)ic dala) and MeV/cm (macroscopic
data).
Range and straggling data is included for electrons, positrons and
charged particles. No range or straggling data is included for
photons and neutrons.

4) Implementing Epicshow
As ill tile case of EPIC, Epicshow is designed to run on virtually any
computer. As distril)uted tide code includes standard grapitics interl'aces
t'or IBM-PCs and SUN workstations. This standard interface is so simple
that it can be easily adapted to run on any computer. For details, see
the section on the standard graphics interface.
5) What is Epicshow?
Epicshow is a mouse driven, interactive system; no keyboard or any
input other than l'rom a mouse is required by the user. The computer
screen is divided into two parts: 1) tide upper portion ot' the screen
is used to display messages to users (watch the upper, right hand
corner) and a menu o1' thirty options, 2) the lower portion of the
screen is used to display the EPIC data.
The code starts by identifying itself on the first frame; press
your mouse or any keyboard key to start. The next frame will be the
hydrogen photon interaction data. From this point on the user is free
to select any of tide menu options.
6) Brief Introduction to tide Menu Options
Tide remainder ot' this report explains all ot' tide currently available
menu options and illustrates the results obtained. The reader should
be aware that by the time this report is published these options will
have changed. Not to worry! When you receive the code read tide file
README for the most up-to-date descriptioli of all of the then current
options.
_
First let's quickly review tile available options; then we will see what
results you obtain when you select one ot' them. The t'olh)wing is merely
list ot' all options and a briet' descripli()n o1' each as contained ill 1a
/G _the file PA ,E.DAT thai you receive with Epicshow. Tilts tiles assigns a
keyword t() each ()1' the menu I)oxes at the box ot' your screen. !t' you do
not like the keyword currently used to describe any option, please I'eei
t'ree to change the keyword to anything that you would like to describe
the same option.
The currently available options arc,
1 Lin/Log X = switch between linear and log x stalling
2 Lin/Log Y = switch between linear and h)g y scaling
3 Points = switch between showing and not showing data
points on each curve
5 Freeze!!! = t'reeze the display - select as many options as you
like and then select Freeze!!! again to continue
WARNING - this cannot be used to queue a number
ot' plots- it can ()lily be used to change options
I'()r the next l)h)t y()u request
al'ler you select Freeze!!! the second time select
Same Z to see the data you selected with all ot'
the options y()u selected
6 Zoom X = use the mouse to select the h)wer and upper x
limits ot' the next plot (t() see (lata in more detail)
7 Show All = undo z()()m - sh()w tile enlire x range
8 Ratio = sh()w the ratio ()1'all curves t() tile tirst curve

9 No Bottom = l'reeze tile position o1' tile bottOln o1' tile screen
(prevent BottomsUp from working)
10 BottoillsUp = iIiove tile bottoin ot' tile screell up 1/2" (SOlne displays
use tile bottom o1'each window t'or identification,
wilich overlays the axis labels - this option call
be used to insure you call see tile axis label)
11 Grid + 1 = change to grid + 1 (there are 6 dilTerence grids)
12 Grid - 1 = cllange to grid - I "
(rather than Iny explaining them, you .illS| try them)
15 barn-l/cm = switch I)etween microscopic (I)arns) and lnacroscopic
(l/cm) cross sections
16 Legend = switch between displaying and not displaying the
legend box identil'ying each curve
17 Bigger = make the characters bigger
18 Smaller = make the characters slnalier
21 Photons = select photon data t'()rnext ph)t (same Z and type)
22 Electrons = select electron data t'or next ph)t (same Z and type)

33 Z- 1 = display data t'or Z - 1
34 Z- 10 = display data I'ou"Z- 10
35 Same Z = display data for same Z - repeat last ph)t -
usually used to obtain Postscript otttput
(tile above 5 options can be used It) quickly

you to compare different types o1' tile data on the
screen, side by side)
37 Listing = list data I'or the currently displayed data
(current Z, all ot" electron or ph()toui, etc. data)
38 Pslscript = switch between P()slscripl oulpul ON ilii(i OFF
40 Stop = WItAT CAN I SAY!!!

7) A Guided tour of Epicshow
That's very nice! But what tile heck do these options do?
If you already have the code sit down at your computer terminal now and
I'll take you on a trial run using Epicshow; if you don't have the code
now, you can use your imagination.
When the code is started it first identifies itself by displaying the
following figure; this tells you what version of the code you are using
and gives you your first view of tile menu. Press any button on your
mouse or any keyboard key to continue.

8) Z+10, Z-10, etc.: Selecting a Target
You can use tile Z+I0, Z-I0, Z+I, Z-I and the Same Z options to quickly
position yourself to anyplace in the periodic table. 11'you wish to
see the data between where you are now positioned and where you would
like to be just select a combination of these options to position
yourself. A much quicker method is to use the Freeze!!! option. Let's
see just how quickly we can do this. Assume we are interested in uranium
data. Select the Freeze!!! option to lock the screen and then select Z+I0
nine times and Z+I once and you are there. Select Freeze!!! again, to
unclock tile screen and Same Z to display tile current data - you are now
looking at the uranium major photon interaction cross sections, as shown
in the following figure. This whole process is so fast it takes longer to
explain it here than it takes to acco_nplish this using the code -
essentially as fast as you can press your mouse button a few times you
can position yourself anywhere in the periodic table.
-12-
I , __
9) Freeze!!!
When you select an Ol)ti()n l'roni tile menu, in most cases tile result will
be the next ph)t. Usually this is adequate to display any data. ltowever,
it' you want to display dilTerent types of data on the same screen in
particular positions relative to one another, so that you can compare
them, you may need to select more than one option before the next plot.
The Freeze!!! option gives you this ability.
When the display is locked by the Freeze!!! option, you can select any
. combination of" options from the menu IJel'ore the next ph)t. Just so you
don't get lost somel)lace in the periodic table i)ecause you don't rememl)er
how many times you selected the Z+I() option, note, on the screen, on the
top line in the upper, left hand corner after the program identilication
the current Z is always displayed, so that you kn,_w where you are.
When you have tinished selecting all o1' your options, select the Freeze!!!
option again, to unlock the display - now any option that you select
will produce the next plot. In the above example we used the Freeze!!!al
to tluickly p_)silion ourselves in the periodic table wilh()ul any delay
due to plotting any data between hydrogen and uranium. BehJw we will
see examples o1' using the Freeze!!! command to co,nl)ose l)lots t() compare
data.
WARNING - Freeze!!! cannot be used 1o queue a nu,nber o1'plots to i)e
displayed: it can only I)e iised l() ch_lllge {)l)li()ns for tire next l)lot thai
you requesl.
13-
10) Major, Minor, etc.: Selecting a Type of Data
Tile options Major, Minor, l)eposit, Rallge and Straggle call be used to
display dilTerent types _;_'data. The options Major and Minor rel'cr to
Photon, Electron, Positron and Neutron Major and Minor cross sections.
These options have no meaning and will be ignored l'or charged particles.
The option Deposit applies to all projectiles and defines the expected
average energy loss by the projectile in MeV/cm. The options Range and
Straggle are used here only to apply to charged particles (electron and
positron ranges will appear in the tabulated output, but not in graphic
form).
11) Photon, Electron, etc.: Selecting a Projectile
The options Photons, Electrons, Positrons, Charged (charged particles)
and Neutrons can I)e used to select the projectile of interest. The
charged particles include protons, deuterons, tritons, helium-3 and
alpha particles.
12) Example Target and Projectile Output
The following pages illustrate the results displayed when after
positioning to the urallitllli photon ma,iorcross sections (first figure)
1 selected the options Minor (next figure), Deposit (next), Electron
(note, still Deposit), Major and Minor. Starting I'rom the initial
figure the following five figures were produces using only five
clicks of the mouse: what could be easier?

13) Grids
it' you are interested only in tile general shal)e ()1'lhe data tile
previous figures are adequate. But if' you wan(t() try and actually
determine the magnitude of the data you need a grid. Epicshow
inchndes six ditTerent types o1' grids, starting from the previously
shown tick unarks ()n the border and progressively including more
and more detail. These grids are controlled by the menu options
Grid + 1 (more detail) and Grid - 1 (less detail). The program
starts with only tick marks on the border (as shown on previous
figures). The following five figures illustrate remaining live
grid types innall cases using exactly the same iron_ major photon
cross sectiolls.

17) Ratio
The Ratio option allows you to switch back and forth between showing
and not showing tile ratio ot' all curves to the first curve.
The fl;llowing figure illustrates tile 2 X 2 option. With the first
(upper, left hand) figure on the screen, 1 selected the Zoom X option
and used my mouse to select the energy (X) range 1 keV to 500 keV
(indicated by the vertical lines on the figure). The result was the
second (tipper, right Imnd) figure, showing the energy range I selected.
Next 1 selected the points option: the result was the third (lower,
left hand) figure. Finally l selected the Freeze!!! option, selected
the points option again (to turn off the points), selected Freeze!!!
again and then Ratio. Tile result was the fourth (lower, right hand)
figure showing the ratio o1' all the cross sections to the Total.

18) Lin/Log X and Y: l,inear or Log Scaling
When data is initially displayed the scaling is automatically selecle(l
i)y tile program based ()n tile X and Y ranges o1' tile data; in most cases
the initial plot will by log-log scaled. The Lin/Log X and Lin/Log Y
allow you to change the scaling to meet your needs. The following
ligure illustrates the aluminum charged particle energy deposition.
Tile first (upper, lel't hand) tigure is scaled log.log and is not the
form in which this data is normally presented in publications. For
tile next (upper, right band) figure I selected the Lin/Log Y option
to change the Y scaling from log to linear to obtain resulls in a more
• familiar form that is seen in publication.
In the above case using a linear Y scale yielded results in the form
that we wanted them. The next two ligures illustrate the importance
of using the correct scaling. In this case the aluminum ranges are
presented using both log and linear Y scaling. In this case the linear
Y scaling yields poor results, since we can hardly see anything.
19) barn-l/era: Microscopic or Macr_scopic
The barn-l/era option switches back and l'orlh between microscopic
(barn) and macroscopic (l/cm) cross sections. The conversion from
microscopic to macroscopic using the atomic weight and density
listed at the top o1' each figure. The I'ollowing tigure illustrates
the lead photon and electron major cross seclio,]s in inicroscopic
and macroscopic t'orin.

20) Listing: Tabulated Output Listings
Tile listing option allows you to obtain a tabulated listing of the
data that you are currently viewing. For whatever combination ol'
projectile and target that you are viewing ALl, of the data is
listed. For example, it'l am currently viewing the lead photon
data (any type o1' data - major, minor, etc.), when I select the
Listing option the following illustrates a portion of the tabulated
results that are written into tl, e file EPICSHOW.LST. Three separate
tables are produced: 1) major cross sections ill barns and energy
loss per collision in MeV, 2) photoelectric shell cross sections
in barns, 3) derived quantities, such as mean free patll and energy
h)ss in MeV/cm (these calculations use the atomic weight and the
density listed at the top of each table).

21) Pstscript: Postscript Output
The Postscript option allows you to obtain hardcopy graphics
output. All of the figures included in this report were produced
using this option.
The program starts with the option turned off. Once this option is
selected, to turn on postscript output, the program will continue
to produce postscript output of everything that appears on your
screen, until this option is selected again, to turn off postscript
output.
WARNING - producing postscript files is time consuming and will
greatly slow down the execution of the program. Therefore you
should only use this option if you really need hardcopy output.
See the section on routine files to your local printer to understand
how to route the standard files produced by this program to your local
printer.
A number of options have been added to meet the needs of individual
graphics systems. These include,
22) Legend
Each plot will normally contain a legend box identifying each curve
that is shown on tile plot. The Legend option allows you 1o switch
between showing and not showing the legend box. Once you become
l'amiliar with tile type o1' data being displaying you may not need the
legend box, and visual resolution ot' the data caa be improved by
removing it from the screen.
- 20-
23) Bigger and Smaller: Character Size
The Bigger and Smaller options allow you to change the size of all
characters displayed on the plots - NOT in the menu boxes; these
are fixed - only those around the plot. On low resolution screens
you can use the Larger option if the characters are not clear. On
high resolution screens you can use the smaller option to make all
characters smaller, thereby leaving more area of the screen available
to resolve the actual data.
• 24) Bottoms Up and No Bottom
Some X-Windows systems insist upon using the bottom of the screen
to identify each window. This identification can overlay the X axis
labels and make it impossible to properly identify the data that
you are viewing. Each time that the B(_ttomsUp option is selected
the lower limit of the plot is moved up 1/2"; if you have the
problem described above, this option will allow you to eliminate
it. No Bottom disables the BottomsUp option for the remainder of.
your run; this has been included as a safeguard, so that once you
llave used BottomsUp to properly size your screen, if you later
inadvertently select BottomsUp nothing will happen, if you have
• disabled it by selecting No Bottom. Note, No Bottom does not switch
the BottomsUp option on and off- it absolutely shuts off BottomsUp
h_r the entire remainder of your run.

25) Interpolation of Data
All of the data in these data bases are in simple tabulated form where
the tabulated energies have been selected to allow linear interpolation
to any energy between the tabulated energies.
WARNING - if you use the Listing option or any other means to obtain
data from this system for use in any application, in order to obtain
reasonable results it is imperative that you interpolate the data
exactly as it was intended to be interpolated = only use linearQ
interpolation.j,
26) Availability
Epicshow is currently being made available to data and transport experts
throughout the world who are reviewing all of the EPIC data. Once this
review phase is over and the data libraries updated to reflect all of
the feedback, this code will be made available to all potential users.
27) Using your mouse
Epicshow avoids using any mickey mouse tricks that you would have
to remember if the ditl'erent buttons on a mouse served different
purposes. To select an option press any button on your mouse; they are
all treated as identical.

28) Size of Data Bases
Currently the original data bases in character h)rm are about
4 megabytes each h_r photons, electrons, positrons and neutrons
and about 2 megabytes for the charged particles.
When converted to binary form for use in applications each o1'
the data bases is roughly half the size of the corresponding
character files.
For use on individual computers these binary files are distributed
in compressed hwm, which again halves the size ot' each file.
o
In summary, to distribute the binary files requires roughly
4 1/2 megabytes o1'disk storage and to uncompress and use them
roughly 9 megabytes of disk storage.
29) Epicshow's Standard Graphic Intert'ace
This program comes witll standard graphics interfaces for use on
IBM-PCs, or connpatil)ies, and SUN X-Windows terminals, or compatibles.
For use on other connputers you must supply the graphics interface
for this code.
STARPLOT = initialize the disj_iayENDPLOTS = terminate the displayNEXTPLOT = initialize screen hNrhext plot (blank the screen)PLOT = inove or draw from last to present coordinatesPEN = select a color (l=0 to any positive nulnber)MYSIZE = define local display sizeMOUSEY = mouse handlerBOXCOLOR = fill a reclangular area with coh)rSHOWTEXT = display text to screen and/or postscript liltSHOWSCRN = displalv text only to screen
d#
All of these are subroutine calls. STARPLOT, ENDPLOTS and NEXTPLOT
have no arguments. The argulnents for the others are,
PLOT(X,Y,I)I = 2 - draw to (X,Y)
= 3 - move to (X,Y)
PEN(I)I = 0 to any positive integer

30) Postscript Output to Local Prinler"i
When producing Postscript t'ormatted output this program writes into
a file named PLOTTAB.PI,T. When each ph)t is finished the program
does a system call,
CALI_ SYSTEM('sendph)t')
to execute a file named sendplot. This file nnust direct PLOTTAB.PLT
to your h)cal Postscript printer. Tile actual contents ot' this file
will vary l'rom COml)uter to computer, I)ut generally it is merely a
single line, as you would type it on your keyl)oard to direct a lile
to your printer. For example, on a SUN workstation, sentdl)lol is an
executable tile conlaining the I'olh)wing single line,
ipr-h PLOTTAB.PLT
- :25 -
WARNING - most printers will make a copy ot' IH,OTTAB.PI;I" and place il
in a gueue to be printed, ()r delay unlil printing is completed. Either
ot" these approaches will work with this code. I|owever, you should I)e
aware that immediately al'ler the system call this program will start
writing the next Postscript plot into I_LOTTAB.IH;I ", so that you must
not use a symbolic link or anything else that will cause your printer
to directly ret'erence and read PI_OTTAB.PI_T while it is printing - il'
you do, the tile will be changing while your printer is trying to
print it.
