Description

The High Momentum Particle Identification Detector (HMPID) is a proximity focusing ring imaging Cherenkov (RICH) for charged hadrons identification at momenta 1< p < 3 GeV/c for pi and K and 1< p < 5 GeV/c for p. The HMPID uses liquid C6F14 as radiator medium. The detection of the Cherenkov UV photons is carried out via CsI coated photocathodes and MWPCs. To ensure a stable particle identification in the long term operation of LHC, this high technology detector requires a sophisticated control system responding to industrial standard for robustness, ensuring reliable remote operation. The HMPID Detector Control System (DCS) has been conceived and implemented in this perspective using the PVSS SCADA environment and Programmable Logic Controller (PLC) as control devices. In this talk the DCS is presented highlighting its finite state machine structure. The evolution towards an ‘Expert control system’ providing error automatic recovering is discussed. Perspectives to integrate Adaptive features providing device feedback (e.g.: gas gain constant via MWPC HV correction) are also explored.
