2018-10-15	Léa, Dirk, Julien, taka, Saiya, Mitsunari	Small run summary Runs0016-0019	- Cut busy propagation from BP, dragon on local clock - 7 GotoSafe and GoToReady for the ECC due to too high temperatures so switch ON/Off of the Modules/BP: 1) 1 module OFF: 10.1.6.28, 2 BPs OFF associated to module 10.1.6.24 and 10.1.6.27
Léa, Taka, Julien, Seiya, Dirk	writing speed limitation in data taking	1 ZFW: validate speed 300 MB writing speed 8 ZFW: validate 8* 300 MB/s writing speed 16 ZFW: writing speed: 16*150 MB writing speed. Maybe problem due to the disk. To investigate

2018-10-14	Eric, Dirk	All (DATA) fibres straight now!	There are straight and crossed fibre patch cords (AB->AB and AB->BA)! They are obviously used indifferently and mixed on our site. :-( The fibres in the IC-PP that are connected to the couplers are all yellow! (No colour code to trace them.) We have chosen the same convention as on the transceivers for input/output of the LC connectors Problem/drawback: All fibres at the IC-PP are now reversed. Need to think/investigate that (last?) point. All PP boxes now closed and secure. Should not be touched any more without agreement by INFRA experts!
2018-10-14	Dirk	Direct measurement of TX lasers	INFO: Direct measurements can be done without danger for Photom-211 測定範囲 -70 ～ +5dBm according to datasheet. That is 3.16 mW to 0.1 µW.
2018-10-14	Léa, Dirk, Julien	First full-cam data run up to 15kHz!	That is what we would have liked to see last week. Now it's Champagne time. :-)
2018-10-14	Julien, Eric	Fibres DATAsp1-6 tested	Optically, between DC and Cam.
2018-10-13	Léa, Dirk, Julien	Run0015	Still no UCTS(/TIB); fibre broken between DC and Cam. Running with half-cam and two additional missing modules (BP problem): 6.24, 6.27. - r0015 all events (at runstart), 300Hz and 10kHz, but ZFW problems (testing with 16 instances).
	ALL	Door knob!	Falling apart from the CC door. Urgent action needed. (Bigger screw?)
	Taka, Seiya, Mitsunari	Fiber Check	We checked optical connection between DC and Camera because some labels were lost due to UV damage. We checked Data2, Data 6, SlowControl and UCTS. Only UCTS had a problem (no splicing at Drive PP). The rest where OK.
	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.
	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	Creation of logbook
	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.
