  1. CONSOLIDATION CPS-BL SYSTEM V. Prieto Hermosilla AB/BI/BL

  2. OUTLINE • The CPS BL Monitoring system • Functionalities • Main Problems • New Options: LHC-IC Test on PS • Planning CPS_BL SYSTEM

  3. PS LAYOUT PS:100(4 SECTORS) TT2:8 nTOF:1 TOTAL BL: 164 AD:2 Injection: 6 Booster:32 (2 SECTORS) Transfer:10 ISOLDE:10 CPS_BL SYSTEM

  4. PS BEAM LOSS • ACEM (Al Cathode Electron Multiplier Tube) • Isat=100mA (Average anode current)(6.107particles in the ACEM/10ms) • Integration mode (fixed Gain)+ADC • Integration mode +Analog acquisition. (OASIS) • -800V<Vp<-1100V • Video (display 8 bits) + Survey (read out 12 bits using 8MSB, every 100ms) CPS_BL SYSTEM

  5. MAIN PROBLEMS • Old system: 1980. • Performance limited by the electronics. • No spares for electronics/detectors. • Obsolete CAMAC Racks. • Every detector has to be dismantled and calibrated every year. • Non standard system: different from SPS and LHC. CPS_BL SYSTEM

  6. SPS (LHC) BEAM LOSS • Ionization Chamber • N2 filled • Vp=800V (1500V) • SPS integration mode (Variable Gain)+ADC(15 bits) • LHC no gain change • Survey CPS_BL SYSTEM

  7. LHC-IC TEST ON PS • Two chambers installed on the S16 of the PS (August 2007) • One in parallel with the beam pipe. • One perpendicular to the beam pipe, on the magnet. • Data taken to compare it with the actual BL system (with the same electronics or directly). • New position needs to be decided CPS_BL SYSTEM

  8. FIRST RESULTS IC1&IC2 (Direct measurement) CPS_BL SYSTEM

  9. FIRST RESULTS Electronics saturated IC1&IC2 (LHC electronics) CPS_BL SYSTEM

  10. FIRST RESULTS IC vs. ACEM with PS electronics IC vs. ACEM (direct current) CPS_BL SYSTEM

  11. NEW SYSTEM • Signal Cables: re-used with adaptors. • HV Cables : re-used (Main distribution changed on 2006) • Electronics: new (studies starts in March) • Detector: new (LHC type) • Mechanics: new (LHC type) CPS_BL SYSTEM

  12. PLANNING • We are going to install and test: • 8-16 IC’s in the PS. • LHC Electronics and Software in the b.368. • The threshold comparator program and the combiner program needs a modification but the Technical specification documenthas to be done before the software modification. • The studies for the new electronics start in March.
