GIF++ installation and schedule meeting

Thursday 11 Feb 2021, 11:00 → 12:20 Europe/Zurich

Remote only (CERN)

Giuseppe Pezzullo (CERN), Martin Richard Jaekel (CERN), Federico Ravotti (CERN)

11:00 → 11:05 New Announcements

IMPACT Declarations 2021 : 
Please update the label on your setup. (Needs to start with 16xx)

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

Call for Muon Beam Time  :  CLOSED
----------------------------------

F-Gas Inventory - EP :

Usage at large experiments known.
In case you use F-gas in your lab for small setups or R&D - please contact R. Guida !!

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

Access System Maintenance  :

Two days of Access System unavailable.
Currently planned in the first week of March (2nd-3rd)  - During these 2 days the source will be OFF.

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

 Gas detection annual maintenance: 

One day of maintenance. It will happen on March 3rd. Access to the bunker possible.

- Testing  flammable gas supply valve power off -> iC4H10 will go off for some minutes
- Testing the flashing lights and local sirens

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

New gas installation request for NA61 & NA64: 

Proposed date: together with the annual maintenance in the week 18 (03-07.05)

Installation of a new gas patch panel for the NA64 (upstream GIF++). In principle we will need to stop the neutral gas supply for 1h in order to connect a two ways valve starting from our patch panel in the preparation area. In the meantime, also the iC4H10 line will be stopped at least for half a day. It will be needed in order to connect on the same line (bldg. 909), a new one for the NA61 experiment.   

Irradiator Maintenance  :   NO OPERATION  !  LIMITED ACCESS !

Scheduled  : Week 9  (01-05.03)  Cancelled because of COVID-19 restriction
Fall back    : Week 18  (03-07.05) in case first date is not possible due to CoVid travel limitations

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

11:05 → 11:15 Muon Beam Scheduling 2021

Preparation and Scheduling of Muon Beam Time 2021

GIF Test Beam 2021 Week Overview.xlsx

Deadline passed. Beam request submitted to SPS Physics Coordinator last Saturday.

North Area Physics : 12.July to 14.November 2021
We expect to receive the first version of the NA schedule (including GIF) in end of April.

We now need to start the space planning for the beam weeks.
Please provide either a CAD drawing (preferred) or food-print (frowned upon) of your setup so we can see how / if they can be aligned along the beam line.

11:15 → 11:30 Weekly planning

WILL BE UPDATED DURING THE MEETING !!!

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

Weekly Planning :   https://teamup.com/ksvh7dak8mub8k7xpe 
UPSTREAM :          Default filter settings :  2.2 
DOWNSTREAM :   Default filter settings :  1

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

ATLAS - MM :
3 long term chambers placed (on the ceiling), operational.
2 chambers coming next week. Discussion started in order to install another chamber in front of CMS-CSC

ATLAS - sTGC :  New stand for flushing chambers before testing operational. Chambers arrived from Chile. Continuing with the standard test.

ATLAS - sMDT : 
Gas quality will be changed from class II to class III (bottles ordered and expected next week) OK!
REQUEST : Running at Upstream 10x latest after Margaret's scan starting from tomorrow till TUE 16th. Once this is done, another request is to running at Upstream 4.6x

CMS - CSC:  Progressing with the activity to resume everything after the long stop. Still some source off needed. 

EP-DT2 :  System restarted. The aging test with eco-friendly gas mixture are going well. 
Request : Once per month test with Ar, operated from a local bottle.

CMS-DT:  Expected to return to bunker later this year. INFN still blocking activity outside Italy. 

EcoGas:  New detector installed. Restarted. Test campaign resumed using eco-friendly mixture (HFO).

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 and operational during this week when we had a R134a stop. Request to have a 6h source OFF scan in order to continue the test started yesterday that couldn't be finished because of the power-cut. From now on, they will try to have a source OFF scan with the upstream abs set to 333 for most of the time. Indeed, there will be the need to switch OFF completely the source for few final step during the scan.  

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

11:30 → 11:35 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)

11:35 → 11:40 Long Term Planning

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.

• https://lms.cern.ch/ekp/servlet/UNIVERSALSEARCH?ACTION=SEARCH&KEYW=atex 
• https://lms.cern.ch/ekp/servlet/ekp?PX=N&TEACHREVIEW=N&PTX=&CID=EKP000039939&TX=FORMAT1&LANGUAGE_TAG=en&DECORATEPAGE=N

Patrol rights : Will be reset before the Muon Beam  (July).
Please contact Giuseppe for re-qualification.

Training Session for CESAR to be organised before beam time.

11:40 → 11:45 Infrastructure & Upgrades to the Facility

Improvements needed or planned for the facility.

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

Monitoring of primary lines to be done. This year we will have the monitoring of the neutral gas (Ar/CO2/Helium/N2), instead next year it will be done also for the other (iC4H10, R134a, SF6, CF4 etc.). This signals will be then available in PVSS.

Cooling system expected to be back on 15.02.

On going discussion for main HFO gas supply line. 

Removal of the fire detection interlock with the GIF++ control room. It should happen in the next couple of weeks. Since the signal is an 'active high' there won't be any impact on our equipment. Everything will than be checked when the times comes for the next AULs testing. We will try to test already with the gas detection annual maintenance if possible scheduled for March

Power-cut in the EHN1 (yesterday Feb 10th) due to an unintentional action on the AUG (Arrêts d'Urgence Généraux). Downtime for the facility ~1h. After today's meeting, and as far as the users could check, there was no main issue on the setups. In case, this problem will be followed during next days.

Increasing of R134a consumption -> to be followed

Problem with R134a on Monday from 14h29 to 16h30. The issue was due to a mechanical switch (used for the swapping of the freon batteries)  that didn't work.

GIFCS-Pytimber app issue still under investigation
