PHOS APD Bias Control
• Goal: To develop software for the PHOS APD bias control that uses the agreed ALICE standards for detctor control and coniguration.

Different ways for controlling the APD bias voltages
• Labview interface used in 2004, uses the RCU-sh interpreter via SSH. Minor modifications needed in order to to work with new firmware (2-3 days)
– Does not comply with agreed standards.
• Micro code on the DCS command line via the the RCU-sh command interpreter.
– Useful for debugging, but to tedious and difficult for upcoming beamtest– Does not comply with agreed standards.
• APD bias control based on ROOT, DIM and FEE server/client software developed in Bergen. Huge progress made Dec 2005 – March 2006 by Bergen/Oslo. Some more development needed (2-4 weeks).
– Complies with ALICE standards.– API for APD bias contrloll can be integrated in the final DCS system.– Could also implement FEEC temperature monitoring and logging.
