Cryogenics
The operation of the cryogenic infrastructure is done by TE-CRG-ML.
Relevant NXCALS variables are:
- QLF[bench]_S_[sensor] for horizontal benches. Example: QLFA1_S_TT147 is the bulbe temperature sensor in bench A1

Quench protection systems
TE-MPE-MP is in charge of all quench protection systems. In their website you can find information about energy extraction, quench heater and CLIQ systems.
Quench heater power supply (DQHDS):
- In Cluster A, F, and G: 11T-DQHDS – https://edms.cern.ch/item/EDA-03933-V2-2
Data acquisition and quench detection
PotAim with NI DAQ
The PotAim cards are legacy analog cards for galvanic isolation, amplification and quench detection. Their cabling schema can be found in EDMS 1034864. The NI DAQ hardware and software is maintained by BE-CEM-MTA.
