Vacuum Controls Final Design Review schuhs@slac.stanford.edu
6 April 2006
Charges to the Review Committee1. Evaluate the presented design against LCLS physics and performance requirements.
In particular:Does the proposed control system provide appropriate status and control signals to the vacuum system users (vacuum experts, physicists, operators)?
Is the PLC adequate to perform all the required interlocking functions?
Do the proposed valve interlocks adequately prevent the spread of vacuum leaks in the beam line?
Does the proposed gun waveguide vacuum interlock adequately protect the gun from vacuum-related arcing?
Do all the proposed waveguide vacuum interlocks adequately protect the klystrons from vacuum-related arcing?
Are the proposed outputs to the MPS adequate to prevent the electron beam from striking a valve?
Does the proposed plan to shut off ion pump power supplies after a smoke alarm adequately protect against fires in cable trays?
2. Identify any other technical issues not already addressed in the presented design
3. Determine if the presented schedule and plans for design, procurement, and installation are reasonable
4. Identify any safety or environmental issues that have not been addressed
5. Write a report of comments, findings, and recommendations

Valve InterlocksRequirements:
Automatically close valves to isolate regions with bad vacuumAutomatically close valves in controlled or permitted accessNotify MPS when valve is closed to prevent beam from hitting valve100 msec response time (valves are slow valves with ~500 msec closing time)
Solution:Set points stored in gauge controllers and pump controllersPLC receives set point status from controllers (24V digital inputs)PLC receives access state from PPS (24V digital inputs)PLC controls valve solenoid (24V digital output)PLC sends valve state to MPS (24V digital output)Interlock logic is a PLC ladder logic routine: monitor inputs, close valve if an input is faulted

Pump Interlocks
Requirements:Turn off injector vault ion pumps if injector vault or laser room VESDA smoke detector asserts alarm
Injector vault cables run over laser room ceiling
Solution:PLC receives status of injector and laser room VESDA systems (24V digital inputs)
PLC controls pump controller high voltage (24V digital outputs)
Interlock logic is a PLC ladder logic routine: monitor VESDA status, turn off pumps if VESDA system sends alarm

Waveguide Vacuum InterlocksPurpose:
Inhibit RF output from klystron if vacuum pressure in RF waveguide is high, in order to avoid arcing. Arcing could damage RF windows or the RF gun.
Background:Existing waveguide vacuum interlock for linac klystrons:
Measure pressure at output of klystron
If pressure exceeds set point, send fault signal to Modulator Klystron Support Unit (MKSU)
MKSU inhibits RF output from klystron
Features of existing interlock:Fast: gauge controller wired directly to MKSU
Simple: one gauge per klystron
Some existing interlocks are more complicated: Positron source, PEP injectorMultiple gauges and pumps are interlocked to each klystron

LCLS Waveguide Vacuum Interlock Requirements
Modify waveguide vacuum interlocks for the following klystrons:20-6: New waveguide directs RF output to LCLS Gun
20-7: New waveguide directs RF output to L0-A in LCLS injector
20-8: New waveguide directs RF output to L0-B in LCLS injector
20-5: New waveguide directs RF output to TCAV0 in LCLS injector
21-2: New waveguide directs RF output to X-Band section in Sector 21
Goals for modified interlocks: Monitor pressure everywhere in waveguide, not just at klystron output
Response time: at most 8 msec slower than existing system (8 msec is 1 beam pulse at 120 Hz)

Response Time of New InterlockGauge controller or pump Controller:
Cold cathode gauge controller response time is 15 msecPump controller response time is 650 msec
PLC logic: <4 msecResponse time estimate of 3.6 msec per Allen-Bradley worksheet (see Design Report, Appendix G)Response time <3 msec measured for ControlLogix PLC at SNS (see Design Report, Appendix F)
External Relay: 2 msec (see Design Report, Appendix H)
Total: 6 msec + gauge/pump response time. Meets requirement of 8 msec + gauge/pump response time.

PLC vs Hardware Summary BoxPLC
AdvantagesNo additional gauge / pump wiring needed. All gauges & pumps already wired to PLCPLC hardware well suited to interlockingEasy to modify interlock logic if desired
DisadvantagesPLC adds ~5 msec to response timeRely on vacuum PLC for RF interlock
Hardware Summary BoxAdvantages:
Faster interlockProven to work at positron source klystronsRF interlock independent of vacuum PLC
DisadvantagesAdditional hardware summary box neededAdditional gauge and pump wiring required Difficult to change interlock logic

Vacuum Controls Hardware Failure ModesSystem Power Failure
Valves close, pumps turn off, interlock outputs go to safe states
PLC Power FailureMaster crate powered by UPSSlave crates can safely be powered off. Interlock outputs go to safe states.
Disconnected PLC Cable:Set point cables appear as faults when disconnectedOutputs to other subsystems appear as faults when disconnected
24V Power Supply FailureValves close, set points appear faulted, interlock outputs go to safe states
Component Power Failure:Interlock outputs go to safe states
Network Failure:PLC performs all interlocks without need for network
Loss of Site Compressed Air PressureAir reservoirs hold enough air to close each valve once

Installation, Maintenance, SparesSLAC Mechanical Fabrication Department (MFD) maintains mechanical hardware and pigtails
SLAC Controls & Power Engineering (CPE) installs, tests, and maintains controls equipment
All work is performed by qualified CPE personnel
Installation, testing, and maintenance of vacuum equipment will follow established CPE procedures
Work on high voltage equipment or cables will follow CPE high voltage procedures
CPE determines need for spares; most components are commercial off-the-shelf devices with short lead times
