Nov.06 F. Spada (Rome) G.Rybka (MIT)• UG Script Control implemented ok• Box-C Functional Check ok - 1 Flipper Valve stuck (remove in FM) - QM Canister Leak fixed (FM ok) - Spirometer / Gasgain-Monitor off

Dec.06 F. Zhou (MIT)• Box-S Functional Checks ok - V2a, V2b leaky (QM RV mod. – FM ok) - Transfer & Mixing @ 16 bar ok - Kulite sensor U noisy

Jan.06 J. Hattenbach (RWTH) • Check Gasgain in TRD Modules • Check Circulation-Flow• Prepare QM TRD-GAS TVT

Assembly at MIT 2 months

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

TRD Manifolds• 20 / 16+4 aluminum bodies machined• Flat Viton sealing modified• Production sequence finalized• QM gastight and functional• FM Manifold cabeling received Connectors shipped to Rome UGPS ready in Mar.07• QM ManifoldSQ tests in Jan.06 FM ready for octagon in Mar.07

- 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
