Solenoid Coil Test Weekly Meeting
Location and Time
- Fri 17-Dec-2010 10 am ARC 428 (later time due to delayed opening due to snow)
Agenda
- Operational experience - all
- what worked, what didn't for coil 1?
- what should we do differently for the next coil?
- what coil will we test next?
- what might we consider doing differently in the hall?
- distinguish between "must haves" vs "should haves" vs "would like to haves"
- have we documented our experience?
- Puzzles and problems to be addressed before next coil test
- improve cryo system
- cold traps
- field polarity reversed
- sub-coil inductances appear to be backwards
- inductance seen on splices
- USB device wiring problems
- other wiring, cable and connector problems
- total coil inductance disagreement
- slow dump doesn't work
- understand fast dump circuit
- measure fast dump resistances
- understand Danfysik ramp-down mechanism
- vapor-cooled lead blockage
- can anything be done to avoid another one?
- improve ability to adjust quench detector
- use new sensor for vapor-cooled lead voltage drop
- isolation and current-loop readout for critical signals
- interaction via Zener and Dataforth clipping
- UPS on Danfysik boards and contactor
- improve PLC cryo and MPS algorithms (in preparation for non-expert use)
- simplify many operations
- improve PLC early problem detection
- improve PLC cryo control under varying CTF operating conditions
- add more HMI screens (may need license upgrade)
- simplify existing screens
- additional HMI license, get second computer working
- more pre-defined trend plots
- did we ever implement guard shack notification?
- automated elog entries
- update drawings and documentation
- where is manpower to make improvements?
