What Came Before…

(my personal collection of accelerator data acquisition)

>TESLA Test Facility at DESY, Hamburg

>Access to accelerator process variables from MATLAB, C++ (read/write)

>Easy to write data acquisition software, scan parameters, record variables…

>Data stored in .MAT, ASCII & ROOT files

>No common data format

>Experts required to set up scan, analyze data…

>SLAC LINAC at Stanford, California

>VAX-based control system

>Scan software to determine the dependency of a variable on a parameter

>On-line display & fits

>Writes MATLAB 4 files for further analysis

22


Design Goals

>Have a universal scan and data acquisition software

>Well-tested scan core

>Universal GUI to set up scan easily

>Specialized GUIs for easy access for regularly performed scans

>Error checking and treatment

>Common HDF5-based file format for easy access from any data analysis code

>Automatic generation of logbook entries

>Link to auxiliary information on accelerator configuration

>Synchronized data acquisition

33

Data File Format

>Hierarchical format to store Instruments

>Based on HDF5

>Readable from Matlab, Root, Mathematica…

Accelerator Data Acquisition

Many accelerator measurements consist of the following tasks:

>Control 0…N actuators

>Acquire 1…M measurements

>Analyze data

Important features

>On-line analysis

>Reasonable error handling

>Robust code for use by other persons than the programmer

55


ADAQA Layers

>ADAQA consists of several separate building blocks

>Applications, written by different programmers, make use of the same data acquisition code

>Instruments gather connected devices

>Logbook

>Common data storage format

>Online model*

>Device information server*

>Synchronized data acquisition

* ongoing work, not yet ready for prime time

66


ADAQA Layers

>Tree-like structure:

>Many devices (roots)

>One data acquisition core (trunk)

>Many applications (branches)

>Building blocks can be exchanged

Synchronized Data Acquisition

>All VME crates for diagnostics are equipped with an Event Receiver

>Connected with a star topology network to the Event Generator

>Supported for:

>BPMs, Bunching monitor, RF, …

>Ongoing work:

>Laser shutter, oscilloscopes, cameras

ADAQA Applications



• General purpose camera display andanalysis tool

• In every day use for different kinds of cameras and screen monitors

General Purpose Scan Tool



the future…



• Scans can be stored in Template files• The last scan is always stored as template

–“Repeat Last Scan…”-Button

• Data files are scan templates as well–All scans can be exactly repeated

• Templates can handed over to the scan tool at startup–example: extracted charge vs. gun phase scan

Scan Templates



Specialised Scan Tools



Automatised logbook entries



• General and specialised scan tools are possible with ADAQA–a wide variety of tools is available

• Common data format• Templates

–data files are templates – for all tools

• Actions–e.g. automatic screen insertion or background subtraction

• Analysis functions

• Automatic logbook entries

Scan Tools Summary

Why?

•less radiation•higher recording speed (10Hz/100Hz)•independent of the workstation (CPU and memory)•system is similar to SLS (Tomcat, in operation, 1* PCO Edge)
