Detector Control System of Silicon Drift Detector in ALICE Jiří Král Czech Technical University 1 CSC 2007
DCS ? ? ● ● ● 2 provide control of large numbers of electronic devices gather information about current state (health) of the experiment safety & fast INTERLOCK reaction CSC 2007
Experiment The big picture Control System Accelerator 3 CSC 2007 Data Acquisition Offline Trigger
Configuration and calibration data Data smoothing ● Enable DAQ frontend and crates tresholds ● V set, I max ● Alarm tresholds ● T max, En/Dis Chip enable/disable ● Ramp speed ADC range and calibration data ● ● ● 4 CSC 2007
Why is the status data important ● ● 5 Many things can go wrong – cooling plant breakdown – chip burn / short circuit – power failure Just to know, what is going on To identify physically not valid information To protect hardware CSC 2007
PVSS ● ● ● ● 6 PVSS is a SCADA system by ETM Database oriented, database driven Interpereted Distributed Expandable (API) IDE Monster CSC 2007
Data, where do they go, where do they come from. . . Recipe PVSS Status 7 CSC 2007
