INSTALLATION IN PHENIX

December 8th, 2008 – 4PM EST :: HBD HV Control & Monitoring System successfully installed in PHENIX

Due to the HBD Simulation Project, the installation process without big complications!

TS5 has been powered up and connected to the HBD mainframe on the bridge.

The mainframe rack which is shared with the RXNP guys, has been powered up.

ALL 6 Run9-modified 1471Ns, which have been crash tested and prepared for installation since last Thursday continuously day & night, were installed in the 1458HP mainframe.

ALL 40 channels (GEMs & Mesh chn) have been ramped up and measured via Fluke by controlling them one by one through the HV Control System, which was run on a laptop connected to the PHENIX wireless.

The installation channel check procedure automatically ramped & disabled channel by channel after measurement.

The channel check has been completely successful!!!

OUR HV CONTROL :: FAQ!

How do we want the HBD to operate?

Operational & Standby Voltages Forward & Reverse Bias: dV is set manually by user for key voltages Trip Settings: GEMs (~165mkA?) and Mesh (~20mkA?) HV Control will be connected to the P/T database (update every 2min) and can so

adjust operational/standby voltages based on layers WE need to set automatically!

Questions? Ideas? Comments?
