- MIPO.
- De-risk strategy for rf at Step V.
- Low level test at Fermilab, Low level tests at Daresbury or high power tests at Daresbury.
- Location at Daresbury : Plant room or security futures lab. Plant room best but crane presents issues.
- Andy : llrf at Fermilab a non-starter. Achieves very little.
- Chris : Moving amplifiers for locating in Security Futures lab a lot of work.
- All : Better in Pland room.
- Kevin : Automation and interlocking for amplifiers?
- Steve : possible to do more work.
- Shielding requirements for cavity tests?
- Kevin : Need qualified estimate for requirements.
- Tim : Amplifiers up running again next year? Level of system.
- Kevin : Andy to contact safety services at RAL to get estimate of shielding requirements.
- End of July deadline for decision on single cavity test...~ 3 weeks time.
- Agenda : Control.
- No temperature sensors on water at DL but do have at RAL.
- Need interlocking of all panel openings where there is a risk.
- Kevin : collect and monitor diagnostic data from all rack elements / circuit components.
- Chris : Heaters on both amplifiers - need to interlock / automate.
- Chris : Add network module to interface with Siemens PLCs.
- Change to alternative brand / model of PLC (Omron) for standardisation.
- EPICS, CANBUS.
- ISIS new system all PLCs.
- Pierrick : Use system similar to ISIS to ensure support available.
- Modified version of ISIS logic plan and new software.
- Kevin : Perform precision timing measurements at amps.
- MICE could run with 4 amplifiers and one set of rf cavities.
- Kevin : current aim is to run with 2.
- Andy : Can you tell us what control framework we should use (CANBUS / PLC).
- Need flow chart for control / interlocking of RF systems on MICE.
- Control (currently on interlocks) has ms resolution.
- Interlocking rack will be on mezzanine.
- Do we need feedback control to prevent overdriving RF cavities in a breakdown event.
- ISIS GUIs should be obtained and studied (Action on Tim).
- Andy : LLRF is a self contained device running Linux.
- Compile list of I/Os and formulate a plan / flowchart.
