11:05 → 11:20 Weekly planning

GIFDay01.jpg

WILL BE UPDATED DURING THE MEETING !!!

----------------------------------

Weekly Planning :   https://teamup.com/ksvh7dak8mub8k7xpe 
UPSTREAM :          Default filter settings :  2.2  (10 from 3. Dec until end of year)
DOWNSTREAM :   Default filter settings :  1

WEEKLY ACCESS MOVED TO THURSDAY 17th (day of the GIF++ shutdown).

----------------------------------

ATLAS-MM :
SM1 long term chamber inside bunker (2-3 months). IC4H10 test ongoing.
3 long term chambers placed (on the ceiling) + 1 quad will be installed today THU 10th and swapped with the one that is currently inside. Next week there will be a swap of the gas battery Ar/CO2

ATLAS - sTGC :  New chambers arrived, under test. Problem with the gas system has been solved. Multiple test campaign will follow in order to catch-up with the time lost during the previous week. Chambers arriving from Chile, not yet shipped. Thus, no gas needed during Christmas shutdown. Some problems to solve with one chamber due to high impedance         

ATLAS-sMDT   :  Some noise problem currently under investigation (getting better). From today till end of the year will take data with attenuation 10. Gas quality will be changed from class II to class III (bottles ordered and expected right after Christmas.)  

CMS-CSC:  Issue with cooling - solved. Noticing some issue with the cooling inside the bunker. After checks no problems (like leakages etc.) was found. More water was added to the system. For the rest, progressing with the activity to resume everything after the long stop. 

EP-DT1:   Mara back to GIF. The setup has been removed from the irradiation area and put it aside in the bunker. Sources checked yesterday WED Dec 09th              

EP-DT2 :  Another chamber installed yesterday WED Dec 09th in the EP-DT2 trolley. The aging test with eco-friendly gas mixture are going well. 

CMS-DT:  Expected to return to bunker later / next year. INFN still blocking activity outside Italy. Preparing for the shutdown and most probably switch to low gas flow already today or tomorrow. 

EcoGas:  New detector installed. Test campaign resumed using standard mixture (R134a, iso-butane, and SF6) 

CMS-RPC:  Small trolley installed and operational since last week. Radiation program resumed on trolley 1. Some impedance problem to solve on the new chambers. Regarding the gas kill signal that didn't work when the R134a, an intervention is expected to happen next week on THU Dec 17th 

ATLAS-RPC: Coming back mid December.                       

 

 

 

 

 

 

 

 

 

 

 

11:20 → 11:25 New requests for tests at GIF

introduction, goal of the test, plan, needs

BLM measuring campaign announced / ≈ 100 BLM, 6h approx. Week 45 (November 2nd till Friday 6th ). We will arrange everything in a way that the setup could be installed inside the bunker in the upstream area near ATL-sTGC setup    -> postponed until next year

----------------------------------

 

Bulgaria academy of science -> testing of new type of radiation monitor system

A new setup of ALICE-RPC will come. More news in coming weeks.

Lab on Fiber (LOF) dosimeter

Gas recuperation system to be installed - Responsible : Roberto
4 additional racks in Gas Service area. One containing flammable gas.
FG detection system to be installed, power needs to be provided.
(DELAYED by a few months. Will be first installed in CMS, and only later come to GIF)

EBT3 gafchromic film calibration campaign for CHUV irradiation in CLEAR scheduled for this Friday 06th from 11am to 08pm - DONE -

 

 

11:25 → 11:30 Long Term Planning

Schedule 2021 not yet clear.
Current planned NA beam start : 12/07/2021
        Scenario (1+3) : proton beam until 11. Oct
        Scenario (2)     : proton beam until 15. Nov 
Will be decided beginning of December, and reviewed in March 2021, approved in April

Call for beam time in early December, deadline will be in February !

---------------------------------------------------------

Gas usage at GIF :  we need to compile a table of gas mixture / consumption

Gas training courses : ATEX level 1  and F-Gas training courses.
List of trained people to be collected.

11:30 → 11:35 Infrastructure & Upgrades to the Facility

Improvements needed or planned for the facility.

Speakers: Giuseppe Pezzullo (CERN), Martin Richard Jaekel (CERN)

20201202_145816.jpg

- 2 chillers unit installed and in operation from yesterday 28/10. They have been installed in order to face the shutdown of the general cooling system of the entire EHN1 - general cooling system expected to be back end of January 2021

- R134a supply went off yesterday Wednesday DEC 02nd around midday. It seems that the issue is the main pressure regulator form the building 909 (picture attached). The same problem happened again this morning Thursday DEC 03rd. EN responsible are aware and an action will be taken by the end of the day.

- ATL-sTGC gas system went OFF multiples times last weeks. After investigation and different tests, it seems that the problem was due to a faulty flow cell. It has been replaced and since yesterday morning the system is running.  

- yesterday WED 02nd during the weekly access, the PPE and PPX of the GIF++ bunker were forced. Even thought it was really strange, after investigation with BE-ICS colleagues, the problem has been solved re-arming both doors. A maintenance has been scheduled for next week on Wednesday in order to check possible communication and mechanical faults.
