  1. HBD HV Controland Monitoring System HV, P/T and Gain Variations Manuel Proissl HBD Meeting 04/06/2010

  2. Upgrades For Run10 | PHENIX, BNL HBD HV Control System HBD Meeting :: April 6th, 2010 Run-10 200 GeV : MV vs. P/T The HV has been changed properly according to the measured P/T and its 5 bins throughout the 200GeV run. The following plots illustrate that. The dotted lines represent the edges of the particular bin. HBD HV Control & Monitoring System Manuel Proissl Page 2 of 29

  8. Upgrades For Run10 | PHENIX, BNL HBD HV Control System HBD Meeting :: April 6th, 2010 Run-10 200 GeV : MV vs. Gain The gain has been overall flat throughout the 200GeV run, meaning the HV changes have achieved their purpose. However, the sudden gain increase on WS2-5 on March 16th remains unexplained. HBD HV Control & Monitoring System Manuel Proissl Page 8 of 29

  14. Upgrades For Run10 | PHENIX, BNL HBD HV Control System HBD Meeting :: April 6th, 2010 Run-10 62 GeV : MV vs. P/T The HV has been changed properly according to the measured P/T and its 5 bins throughout the 62GeV run. However, one needs to recognize the changes of different gain operation sets: 2k and 4k. The following plots illustrate that. The dotted lines represent the edges of the particular bin.
