Performance evaluation of the control system for the LHCb muon detector

The muon detector of LHCb will be equipped with about 1380 multi-wire proportional chambers. Within the framework of the CERN control system project, using PVSS as the main tool, we are developing an instrument to manage such a system. Adjustment and monitoring of high and low voltage power supplies, on-line diagnostics and fine tuning of the front-end read-out devices, data acquisition from the gas system and the monitoring of pressure and temperature of the experimental hall are being implemented. The system will also look after long term data archiving and alert handling. The control system performance is currently under evaluation in a cosmic ray station. Built as a final quality control of the LHCb multi-wire proportional chambers, allowing acquisition of data from as many as 600 front-end readout channels, the cosmic ray station is fully managed by means of a control system prototype
