| 2018-10-12 | Léa, Taka, Julien, Seiya, Léa | Data aquisition |
- Pb with slow control connection for the ECC due to a broken fibers. Fiber changed, pb resolved. - In the afternoon, 3 lost of ECC slow control communication due to the interruption between IT-Container/Driver-Container. First time, temperature was already high in the camera, we had to switch OFF the 233 and 400Vfor security reasons. Two other times, we get back the ECC connection quite fast and ECC was in the same state that when the connection was lost. Just no more current in the pulse bar so we have to gotosafe and gotoready again. - During the day, due to high temperatures we have to gotosafe to wait for the camera to cool almost 11 times but never the BP max tempeture went more than 34 degree. The air inside reach at the maximum 26.5 (Carlos validated a maximum limit of 27). - For data acquisition: - we validate for 3 fibers the new connections to the dataswitch fiber. Eric is fixing the one missing or broken. So for now only the right part of the camera is used for data acquisition - No TIB/ UCTS - few runs were taking with data aquisition with no external trigger from TIB. 3 Modules didn't appear busy but didn't sent any data. In those test the busy from the CBP is cut. Those missing modules have to be investigated in more details but due to a lot of slow control deconnection problem and hihj temperature in the camera it was not possible. - One try with no external trigger and clock but with the CBP delivering the clock and pps and using 10 MHz clock as default clock for the dragon. L1 local Trigger didn't generated. No we come back to a configuration of dragon on their local clock but this issue has to be investigated. - Pb with the ClusCo on tcs01. The root propagation for the BPs for the trigger doesn't work. Using exactly the same script it works on CacoOperator. |
