  1. Bob Michaels Report Nov 27, 2012 • Compton DAQ Development • High Voltage Maintenance p. 1 / 5

  2. Bob Michaels, KalyanAllada, AlexandreCamsonne, and DAQ Group FADCCounting Mode Photon DAQ – present effort e-det TBD http://hallaweb.jlab.org/equipment/daq/compton_coda3.pdf https://hallaweb.jlab.org/wiki/index.php/ComptonDaqDev p. 2 / 5

  3. Bob Michaels, KalyanAllada, AlexandreCamsonne, and DAQ Group Test Stand -- FADC for Photons Done: A setup with “fast, modern” hardware. “fast pulse integral” mode data buffered on FADC readout speed 1.1 MHz Future : Random pulsersimulation of particles Inject and extract a ~1% asymmetry p. 3 / 5

  4. High Voltage Maintenance LeCroy 1458 HV motherboard emulator Perl script (Brad Sawatzky) Serial new serial card replaces old motherboards (Javier & Jack) external 24V supply Network Java GUI (Roman Pomatsalyuk) p. 4 / 5

  5. High Voltage Maintenance • Progress • Set up 1 crate / learning (thanks Jack, Javier, Brad, Roman) • Rough count of (a) needs , (b) existing inventory • http://userweb.jlab.org/~rom/SBS_HV_19sep12.pdf • Plan • Fix another crate … • More accurate inventory , larger-scale tests • Scrounge (Hall B , MIT …) and/or buy new units (Wiener) p. 5 / 5 Fini
