  1. FCAL Collaboration High precision design Luminosity Detector R&D TAU Update Halina Abramowicz, Ronen Ingbir, Sergey Kananov, Aharon Levy, Iftach Sadeh Tel Aviv University MPI Munich meeting 17/10/2006

  2. Backgrounds 17/10/2006 FCAL -- TAU

  3. Background - Theta Chen,Tauchi and Schroeder Paper 17/10/2006 FCAL -- TAU

  4. Backgroud - Pt Chen,Tauchi and Schroeder Paper 17/10/2006 FCAL -- TAU

  5. Energy resolution & Digitization No digitization ~ 25% energy resolution Energy [GeV] 17/10/2006 FCAL -- TAU

  6. Cells energy  Mips Cell Energy [GeV] # MIPS 1 MIP leaves 150 KeV tested using simulation of Muons hitting LumiCal 17/10/2006 FCAL -- TAU

  7. High Gain ADC Low Gain Digitization Model At low gain : 5 bins are required for one MIP Investigation: 6,7,8,9,10,11,12 BITS ADCs 17/10/2006 FCAL -- TAU

  8. Results Linear Scale Log Scale Bits Bits 17/10/2006 FCAL -- TAU

  9. Silicon Lab Phase one - Basic setup (I/V, C/V) Phase two - MIP measurements and first sensor design Phase three - Sensor with basic readout elec. (Laser system) Probe station arrived to TAU (Thanks to DESY Zeuthen) Purchase of lab equipment starts (Phase one) Contact local industry Cooperation with TAU Elec. engineering department 17/10/2006 FCAL -- TAU

  10. Summary Backgrounds : the calculations should be compared to the MC simulations. Digitization : 8 BITS ADC maintain energy reconstruction performance. More studies are needed to include noise and to check full event reconstruction (energy & position). Silicon Lab : still in the setup phase  allot of work ahead ! 17/10/2006 FCAL -- TAU
