2. HV-LV-ADC status Sometimes “repaired boards” are not working properly and so I would like to propose you to: – Test and qualify “broken” boards at 904 before sending it at pool – Test very carefully the “repaired” boards at 904 before installing them in the system In this way we can save money (1 KCHF per board) and time 904 test setup is now ready thanks to Hassan, Anton and Giovanni. Hassan will be in charge of the setup and test procedure.

3. HV insulators We have 10 “new generation” of HV insulators in data taking since one year. No problem observed. The 10 custom insulators produced in Napoli are under test at 904. One HV channel broken due to a bad mechanical connection. Broken connector We have a final setup in Napoli to build the insulators. The sizes of the connector is now under control and this should avoid the problem we had on the CAEN connector.

4. Action items New firmware installation HV board calibration by CAEN LV check MAO test Cable and connector to replace (Y and short)
