==================== Tue. Jan. 30th, 2007 ==================== - "status" (Lorenzo, Livio, Pietro, Gabriele) - done: ==== - JFET, Gabriele: systematic noise tests in many configurations - (Alice detectors, different behavior) - (single channel Amptek) - (Cremat puzzle solved: mounting in box with teflon screws not as good as metal screws!!! Amptek is better anyway) - VA2-TA hybrid tests (Pietro+Serghei+Lorenzo): OK - calibration mode, manually with "Pietro-box" - individual addressing extended to 3 chips - (1 chip only mounted) tests OK, shaping tuned - first production boards had defects (seen by Mipot when bonding) => second batch produced and received (to be mounted and tested) - Laser monitoring: - diode mounted with Cremat ampli (Luciano) - tested at the scope (Lorenzo et al): OK - calib signal to Cremat OK - laser OK - Am(241) source OK - repeater for VA2-TA - "Serghei's repeater": OK!!! (tested with source) - ground decoupling - clock driver - modifs transferred to Erik's repeater (Pietro) - Pietro's decoupler tested OK - 20 printed circuits received, components mostly received - 2 mounted and tested - FSSR2 - chain received from Fermilab => to be tested - FSSR2 hybrid and connector - preliminary specs by Pietro, circulated by Luciano - telescope detector mechanics (with VA2TA hybrid) - drawings and prototype done... - to be done: ========== - Laser monitoring: - test with peak-sensing ADC CAEN V556 - write stand-alone program for ADC CAEN V556 (Marco+Lorenzo) - include in the main DAQ program - Combination of microstrip DAQ (VA2-TA) with step motors control - new project for Marco! - FSSR2 - chain from Fermilab - provide: cables?? - provide: software? (Milano ?) - hybrid - meeting to decide final specs - (Fermilab; also Pietro in parallel? decide!) - VA2-TA - complete mounting, 3 more repeaters (started) - mount more chips on hybrids + test - telescope mechanics - finalization of design for VA2-TA/FSSR2 - production - JFET: systematic tests on diodes (Gabriele?) - (2nd priority: VA2-TA hybrid: use calibration mode programmed in labview by sequencer instad of manually by Pietro-box)
