Commenced: 10:00 am
Adjourned: 10:35 am

1) Status
*E-hall is open today.
*Emergency opening on Monday. Turbine issues.
*Warm oil tank.
*One of the insulators cracked. Keep running, but need to monitor tank.
*Following up on reason for EGUN:BIAS trip due to a stage 2 trip from EABT:LIC3B. This was due to losses from EACA. Caused a dozen trips towards end of the test. But detector worked as it was supposed to.
*Observed spikes in charge reading of EABD:PMT0. Irregular. Noise pick up? Not dramatic, but noticeable regular spikes. May hint at developing problem.
*Before end of 2023 year, there was an issue with EMBD:LIC2 (Sudden trips). Did problem come back during the last months? Brandon and AL checked connections, couldn’t find any visible problem. ==> No re-occurrence since last year.
