  1. TMB-RAT Software Update USCMS Slice Test Workshop @ Rice University August 16, 2004 Martin Von der Mey / Yangheng Zheng* University of California, Los Angeles TMB-RAT related Peripheral Crate control software update Plan

  2. Software update after April Emu meeting • Frank created a “tmbtiming” module in PCC for timing in the TMBs (used in May beam test) • Add RAT module XML configuration variable (Thanks to Alex and Rick) • Update trigger modes in TMB/CCB class (ALCT and CLCT self triggering modes added) • Add ALCT and TMB (online/offline) CRC check routines in ALCT/TMB class • Add CFEB/AFEB pulse pattern injector functions in “tmbtiming” module. (Thanks to Jianhui) Slice Test Workshop@Rice University

  3. tmbtiming module • April-May features: • TMB/CFEB delay constants • TMB tx/rx delay constants • TMB scope data for adjusting ALCT and CLCT matching window and delay • Recent additions: • ALCT/TMB online/offline CRC checks (can check raw hit data before DDU ) • CFEB pulse pattern injector • AFEB pulse pattern injector Slice Test Workshop@Rice University

  4. CFEB/AFEB injectors : Why? • Without turning on the gas and HV system for the chamber, you can • debug the TMB-RAT system (maybe other system), • test CFEB and ALCT cable connections, • get TMB and ALCT delay timing constants in a fast way, • simulate the single muon, cosmic ray or test beam patterns … Slice Test Workshop@Rice University

  5. CFEB pulse pattern injector • Generate half-strip patterns for all strips • Control sequence: tmbtiming module  DMB registers  CFEB buckeye chips  pulses on strips • CFEB pulse are well-determined charges. • Input: half-strip patterns for buckeye chips; output: CLCTs • CLCTs generating rate: buckeye rate Slice Test Workshop@Rice University

  6. CFEB pulse pattern injector (cont.) Slice Test Workshop@Rice University

  7. AFEB pulse pattern injector • Generate ALCT patterns • Control sequence: tmbtiming module  CCB registers  TMB registers  ALCT registers  pulses on cathode test strips (1 strip/layer) • CCB provides 500ns gate to enable the ALCT testing pulses • capacitive coupling between test strips and anode wire groups • hot wire mask on ALCT board  ALCT patterns Slice Test Workshop@Rice University

  8. AFEB pulse pattern injector (cont.) • Input: key wire group number; output: ALCT pattern • ALCTs generating rate:  computer instructions rate Slice Test Workshop@Rice University

  9. AFEB pulse pattern injector (cont. ) Slice Test Workshop@Rice University

  10. What’s next • Improve the user interface for CFEB/AFEB pulse pattern injectors (create a new class?) • Get TMB and ALCT timing constants directly from CFEB/AFEB pulse pattern injectors in a fast way • Create the simulators for single muon, cosmic ray and test beam using injectors Slice Test Workshop@Rice University
