Systems & services
Note: this page is in work.
In this page, the main services used by the team are summarized, with links to relevant information sources.
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
PIDs:
CRNLSQLJ0038 — Cluster G satellite
SY-EPC is in charge of the power converters. You can find information about the newer power converters in the SY-EPC-LPC database, and of all of them in the general SY-EPC database.
How to use the General SY-EPC database

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
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.
