  1. TRD GAS Progress • Box-S/C • Manifolds • UG Power Supply AMS TIM, JSC, 9-Jan-2007, Th. Siedenburg MIT-LNS

  2. TRD Gas System SUPPLY CIRCULATION DISTRIBUTION POWER CONTROL

  3. Supply Vessels (Xe, CO2) Transfer Volumes Mixing Vessel TRD GAS Box-S Relief ValveSafety Requirement

  4. TRD GAS Box-C Circulation Pumps Vent Line Pressure Sensors CO2 Spirometer 55Fe Gasgain Monitor Canister

  5. QM GasSystemEM UG-Crate @ RWTH PreTest

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

  7. MIT JAN-04-2007 Inspection at ARDE ok Gastightness 1∙10-5 l mbar/s Shipped to MIT Cabeling in preparation Finished by mid-March 07 FM Box-S FM Box-C Replace Flipper-Valve unitwith Check-Valve Unit (RWTH) Assembly at MIT 2 months

  8. 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

  9. 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 QM

  10. UG Power Supply m.d.i. 6031-S28 29.0V ordered m.d.i. 6031-S12 12.5V ordered Controller for m.d.i. DC/DC major effort Would not protect individual UG-boards Define DC/DC Voltages Power On Control for 12/29V Isolate Subsystems Latch-Up Protection Monitor Operation

  11. UG-Electronics Open Item ListSafe 29V for Kulite SensorsSeparate 5V for TubeAmpSeparate 12V for FV/UGPS • Latch-Up Protection for UG-Board Components: • - 54SX 208/32A FPGA • - LM2941S 12V-> 10V LinReg • - TPS7350 5V-> 5V LinReg • - TPS7333 3.3V->3.3V LinReg • - TPS7325 2.5V->2.5V LinReg • - SN65LVDS390 LVDS-Driver • - AD7476 ADC for P-Sensors • - Si4840DY MOSFET Heater/MV Control • - SUB65P06-20 MOSFET Heater/MV Enable • - SUB85N10-10 MOSFET Heater/MV switch • - LM239A Comparator MV Sense • - Si4544DY MOSFET FV • - Si4966DY MOSFET FV • - MAX225EWI RS232 Driver • HI-508 Analog MUX • - AD620BR UGPS Diff.Amplifier • + TRD-GAS P-Sens., TubeAmp, MCA, Spirometer • - 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

  12. Problem 1Kulite Sensor Supply Current Design: 29V supply directly from backplane 29V-A and -B connected at sensor Loss of redundancy Risk of losing Marotta Valve actuation power Proposal: Diodes and 1kW Resistor at sensor in Box-S Decision needed for FM Box-S wiring at MIT Also twisted pairs needed to reduce noise

  13. Problem 2TubeAmpSupply • 5V shared with RS232 and ADCs • Risk losing only abs.press.sens. • in TRG Gas volume • Proposals • Supply from UGBC-A only • Add separate 5V LinReg • OVC protect. On TubeAmp

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

  15. Simple UGPD Control Without OVC / latch-up protection Keep UG boards and backplane Passive control of 12V and 29V m.d.i. converters Simple board in UGPD – No Controller Delayed power on after 5V on Switched off when 5V off

  16. 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
