        IMPACT Declarations 2021 : 

        For 2021, please prepare a new request, with "GIF - Irradiation 2021" as intervention period.
        If you clone the one from 2020, please review the description and the participant list !

        You will need an active IMPACT to activate the DCM and enter the bunker.
        Strictly no access without IMPACT.
        List of active IMPACTS : PPE154

        Please update the label on your setup. (Needs to start with 16xx)

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

        ATLAS - MM :
        SM1-M31 long term chamber inside bunker since August. IC4H10 test ongoing.
        SA - access request for gas swapping (Ar-Co2) before removing chamber.
        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.

        ATLAS - sTGC :  New chambers arrived, under test. New stand for flushing chambers before testing. Chambers arriving from Chile, not yet shipped. Some problems to solve with one chamber due to high impedance.

        ATLAS - sMDT :  Some noise problem currently under investigation (getting better). Gas quality will be changed from class II to class III (bottles ordered and expected next week)  

        CMS - CSC:  Issue with cooling - solved. Noticing some issue with the cooling inside the bunker. Progressing with the activity to resume everything after the long stop. 

        EP-DT1:   setup removed

        EP-DT2 :  System restarted. 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. Restarted yesterday. Test campaign resumed using standard mixture (R134a, iso-butane, and SF6).

        CMS-RPC: Radiation program resumed on trolley 1. Some impedance problem to solve on the new chambers. Gas kill signal that didn't work when the R134a- FIXED. Proposal to use 4.6 as default attenuation filter for one week - outside sTGC measurements.

        ATLAS-RPC: Coming back for the moment, not before March 2021.

        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.

        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)

        - 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

        - 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.  

        - R134a supply system 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. On January 6th-7th 2021 we had again a similar problem with the R134a.                                                                                      After all this issues the system has been modified and a new panel with a new pressure regulator has been installed (13 Jan 2021), waiting for the overall renewal of the area 909. For the moment, the system it seems to work fine. In any case, we will monitor over the next weeks the status of the R134a line.

          Guidelines for filling in IMPACT requests

          List of active IMPACT declarations : https://impact.cern.ch/impact/secure/activities/accessPoint/YDALC02-PPE154

          General Guideline : One IMPACT per setup.

          • two chambers on individual supports -> 2 IMPACT declarations
          • multiple chambers swapped on same or similar support -> one IMPACT declaration
          • basically, if you need two locations, please make two IMPACT declaration (clone)

          Each Setup should have IMPACT label attached with number.
          Attached documents : CAD file  or  picture.
          Review working hours : if your declaration includes the bunker area, please state the number of hours you want to stay INSIDE the bunker only (for RP purposes).

          CoVid-19 Risk Assessment for the Facility :  https://edms.cern.ch/document/2376286/1

          General guideline :

          • ONE setup to enter the bunker at any given time.
          • All presence at the GIF and access to the bunker needs to be announced via Teamup beforehand (!)
          • Traceability of people on site :  Logbook ! - List all the people you encountered.
