CERN-IPMC Official Thresholds?

Hi CERN-IPMC Team,

Wish you a happy new year BTW !
What are the thresholds values I should set for CERN-IPMC internal temperature sensor please ?

Best regards,
Sylvain @ LAPP

Hello Sylvain,

best wishes for 2025 to you as well.

There are no official thresholds, since this depends largely on the placement of the IPMC and the airflow on the blade. On our boards the IPMC is parallel and close to the read edge of the PCB. Given that the IPMC is perpendicular to the main blade PCB, the IPMC temperature sensor essentially measures the incoming air temperature. We typically see a temperature between 25 and 30 C in the lab. Therefore the thresholds we use are the following:

55 45 35

You may need to adapt this to your blade, but I would not increase the non-recoverable threshold above 55C.

Best regards,

Stefan

Thank you very much !
