  1. TRD Gas System Slow Control at MIT- Cambridge AMS TRD Meeting, CERN, July 2002 U. Becker, B. Demirkoz, P. Fisher, R. Henning, B. Monreal. R. Henning -- TRD Gas Slow Control

  2. Overview • Help Design and Build Control Systems for TRD Gas System Prototype and Flight Systems. • Prototype System • Tested Mixing Program for Prototype Box S using USCM V02. • “Commercial Version” • Test Software and Electronic Prototypes (Roma) for Whole Gas System using USCM V03 • Flight System R. Henning -- TRD Gas Slow Control

  3. TRD Gas System Overview Box S Manifolds TRD 300 Liters Box C Xe 1550psia Mixing Vessel 200 psia 17.6-20.4psia CO2 940 psia Figure 1: Schematic Arrangement of the TRD gas system. All pressure are given at 25 oC. R. Henning -- TRD Gas Slow Control

  4. Prototype System (1) DOUT Box S Prototype USCMV02 RS-232 ADC Power Drivers • Currently Used in Closed System Test (B. Monreal) R. Henning -- TRD Gas Slow Control

  5. Prototype System (2) R. Henning -- TRD Gas Slow Control

  6. Electronics for Commercial System Mixing Program Koutsenko CAN Interface + Guido Board 2 x USCMV03 EPP CAN LVDS • Under Construction • Develop Flight Software • Control Commercial Gas Systems UGBS UGBC, etc. (Roma) Commercial Gas Systems R. Henning -- TRD Gas Slow Control

  7. Box S Electronic Simulator Roma R. Henning -- TRD Gas Slow Control

  8. Flight System USCM AMS/ISS JMDC • Simple Operations • Continuous Monitoring CAN Mixing Program LVDS Gas System • Power • Emergency • Operations Operator Crate Electronics R. Henning -- TRD Gas Slow Control

  9. Mixing Operation • - Mixing Program On Ground and JMDC • - Following Sequence: • Start with Known Mixture in D Vessel. Vent D if mixture unknown. • Fill required partial pressure of CO2 • Fill required partial pressure of Xe. • Vent to Box C when required. • - Minimize ground communication • Gas Transfer Controlled by Time Valve is Open. • Timing of Valve operations performed by UGBS, not USCM! R. Henning -- TRD Gas Slow Control
