1. HBD HV Control and Monitoring System STATUS UPDATE Manuel Proissl HBD Meeting 03/04/2008

2. QUICK UPDATE  “HBD Real-time Simulation Project” since December 7 th, 2007 – making HV control crash tests in the PHENIX environment possible  Discharge Resistor changed to 10K  discharge time issue solved | now ~ 1ms  LeCroy’s attempt to self-restart after trip has been completely blocked by recovery routine on PIC18F4620/8722 Microcontroller on relay board  HV Control for experts with enhanced features, like P/T data life remote access and threshold control, in development Upgrades For Run8 | PHENIX, BNL HBD HV Control System HBD Meeting :: March 4 th, 2008 HBD HV Control & Monitoring System Manuel Proissl Page 1 of 5 Connect Relay Discharge Relay From LeCroy 1471 To Resistor Chain 10K
