Announcements
Next Meeting
Thurs 1-Dec-2011 9:30am CC L207
Minutes
Present: Elliott W, Josh B, Mark S.
Equipment Orders
- Mark still has to order rack parts.
- Mark will produce a desired equipment list in priority order.
- Josh has received everything he ordered (SOE, 435NBX, etc).
Solenoid Controls Redesign
- Jonathan and Rao produced a preliminary P&I diagram, need feedback from Scot et al. concerning controls wiring.
- Function of some valves has changed.
- Order for new vessel will go out soon.
- Mark will order (has ordered?) the shunt replacement.
- We still don't have a good strategy for coil tap signal isolation.
- We expect Giles will work on bringing UPS power to the hall, a 220V 30A subpanel seems reasonable.
- Still don't know the coil inductances, still working on alternative quench detectors.
- Mark will design the new ground fault detector using the existing dump resistor.
- FMEA will help determine the level of redundancy needed (contactor, QD, diodes, UPS power to power supply, etc).
- Yi tested the NI 8-chan (separate ADC for each channel) fast-daq board and is very happy. No crosstalk seen up to high sampling rates.
