|---|---|---|---|---|
| 2018-10-13 | Taka, Seiya, Mitsunari | Door knob! | Falling apart from the CC door. Urgent action needed. (Bigger screw?) | |
| 2018-10-13 | Taka, Seiya, Mitsunari | Labeling fibers | We labeled optical fibers of the data (DATA 1 - 6) at patch panels in Drive contaniner and in IT container. The spare cables have not been done yet because a ribbon ran out. | |
| 2018-10-13 | Seiya, Mitsunari | Connection validation | We validated 12 optical fiber connection (No. 1-6, 13-18) from Drive coontainer to IT container. Strength is -35 to -38 dBm. | |
| 2018-10-12 | Léa, Taka, Julien, Seiya, Dirk | Runs0012 sqq. | No UCTS/TIB today.
These runs have 3 modules missing (as identified in the preparatory phase: 6.21, 6.25, 6.28). According to a quick check, all EventNb=TriggerNb otherwise for all runs today. See RunCatalog for details. |

| Dirk, Taka, Julien, Seiya, Léa | Data acquisition |
- 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. - 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 taken 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 was cut. Those missing modules have to be investigated in more details but due to a lot of slow control deconnection problem and high temperature in the camera it was not possible. Script used in CLusCo: init7_noextTrigger_Test.uic. To not cut the busy, name is: init7_noextTrigger_noBusyCut_Test.uic - 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 dragons. 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. Script used in CLusCo: init7_noextTriggerClock_Test.uic | ||
| Dirk, Taka, Julien, Seiya, Léa | Too high temperatures in the Camera |
- Limit fix to 27 for the aire temperature inside and 35 for the BP temperature. Pression also get some alarms - 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 temperature went more than 34 degree. The air inside reach at the maximum 26.5. | ||
| Dirk, Taka, Julien, Seiya, Léa | ECC lost connection (2 times!) |
- In the afternoon, 3 lost of ECC slow control communication due to the interruption between IT-Container/Driver-Container. Miscomunnication with AMC people... First time, temperature was already high in the camera, we had to switch OFF the 233 and 400V for security reasons. Two other times, we get the ECC connection back quite fast and ECC was in the same state that when the connection was lost meaning state 2 ready. Just no more current in the pulse bar so we have to gotosafe and gotoready both times. After that the current was -247 in the pulse bar... Not understood for the moment - The second interruption happened, when the Moxa switch was reconnected, probably not correctly configured. It was disconnected again. Presently this impacts AMC and drive operation, until the Moxa can be reconnected. | ||
| Léa, Taka, Julien, Seiya, Dirk | Discovered SLOW control fiber lost, fibers changed connection recover |
Interruption. Using UCTS section for replacement. || | ||
| 2018-10-11 | Eric, Armand | Cable splicing | UCTS fibres ready and checked. | |
| Léa, Taka, Julien, Seiya, Dirk | DATA5-upstream broken | Located between DC-PP. and IC-PP. Eric is going to have a look on Friday, when working on the other (spare) fibres. | ||
| Léa, Taka, Julien, Seiya, Dirk | Found correct order of DATA1-DATA6 | We eventually found that the fibres DATA1-6 were connected in (exactly) wrong order to the camera, which lead to a mismatch of switches/modules with respect to interfaces/addresses in osaka.
This is an item for our "learned lessons": The indoor fibres had been labelled (switch-interface), but stayed in Mirca. The new fibres had been confectioned at ORM, and labels had to be "guessed" in one way or the other. |
