TRD Gas Manifolds• Distribute TRD gasflow into 41 segments
• Measure gastightness of individual segments
• Allow isolation of a segment when leaky
• Introduce no additional risk of gas leakage
• Safe operation in globally heated TRD

- EM System working at RWTH- QM System at Rome with new prototype backplane
Schedule:- QM backplane prod. in Feb.- QM SQ in Mar/Apr. at SERMS

Problem 1Kulite Sensor SupplyCurrent Design:
29V supply directly from backplane29V-A and -B connected at sensorLoss of redundancyRisk of losing Marotta Valve actuation power
Proposal:
Diodes and 1k Resistor at sensor in Box-S
Decision needed for FM Box-S wiring at MIT
Also twisted pairs needed to reduce noise

Problem 2
TubeAmp Supply
5V shared with RS232 and ADCs
Risk losing only abs.press.sens.in TRG Gas volume
Proposalsa) Supply from UGBC-A onlyb) Add separate 5V LinRegc) OVC protect. On TubeAmp

Problem 3UGPS Supply
12V shared with Flipper Valves
Risk losing FV actuation power
Proposal:
Add separate 12V LinReg

Simple UGPD ControlWithout OVC / latch-up protection
Keep UG boards and backplanePassive control of 12V and 29V m.d.i. convertersSimple board in UGPD – No Controller Delayed power on after 5V on Switched off when 5V off

UG Power Control Board
Replace UHVG in UG-Crate Gasgain monitor HV from U-Crate
+ Provide individual board SSF for 3.3/5V and Control of 12/29V+ No modifications of UG-Boards+ No Controller in UGPD– Redesign UG backplane discussed with Capell & Lebedev, W.Karpinski may design, 20k€ required
