CPP requirements
Power HV/LV
- HV for muon chambers: 6 HV channels for the 6 wire chambers (+1765V nominal)
- LV for muon chanbers: 6 times +5V and 6 times -5V (nominal current ?1mA?)
- HV for 4 scintillator paddles: 8 HV channels for PMTs (-1800V nomial)
- HV main frame location (existing?)?
- LV main frame location (existing?)?
Chamber Gas
- Ar/CO2 (90%/10%) premixed in bottles
- gas line from gas shed to downstream platform
- gas manifold on downstream platform
- gas flow control though manual rota-meter (flow meter): nominal flow 300 sccm
- gas flow exhaust protected with oil bubblers
Chamber cooling
- under discussion, potentially with dry nitrogen
- no sensory foreseen, neither for flow nor for temperature.
DAQ readout
- CDC VXS crate \#1 is used with all fADC125s, moved to downstream platform
- needs 2 Ethernet connections one for the fan-tray (slow control network) one for the ROC (DAQ network)
- needs 1 fiber optics connection to TI
- One fADC250 for scintillator digitization. Added to TOF crate?
