892/1-D20 (CERN)

Roberto Guida (CERN)

Technical help/interventions

-All technical interventions/requests will take place on Thursday. Giuseppe will be available to follow the requests from the users.

-False floor unstable in front of gas supply panel S01 --> Giuseppe to check

 

-Beam:

-XTDV installation:

planned for July 20 - July 22 (no more news. No reply from EN/Adrian)

After SPS meeting:

1. XTDV installation. Planning is here: https://indico.cern.ch/event/549613/contributions/2228943/subcontributions/200550/attachments/1309592/1958922/GIF_XTDV_installation_EATM.pdf Only the downstream one will be installed. However, the new tables did not leave Portugal yet. This should happen tomorrow. It is possible 1 or 2 days delay w.r.t. the schedule in the presentation;

 

 

- Discussion for HVAC operation:

New settings:

20 C 45% RH

reached 21.5 56%

Humidity setting not achieved (min is 50%)

Humidity is not removed as expected. Discuss with EN-CV-Aziz, Jerome.

 

Other works planned at EHN1 and affecting GIF operation:

1. A heavy magnet MNP22 (60T) needs to be moved inside EHN1. Several options are being considered but, for this activity it is possible that some concrete shielding blocks and some other structures in EHN1 have to be temporary removed/displaced. This can include the temporary removal during one day of part of the exhaust gas line of GIF++. This activity will happen probably in September;

2. The overhead crane rails in EHN1 should be renovated. Details are here: https://indico.cern.ch/event/549613/contributions/2240144/attachments/1309284/1958341/EHN1_rails.pdf This activity will imply one week of inactivity for the cranes in EHN1 in the area where GIF++ is located. This activity is being scheduled at the end of the beam time in the weeks 49-51 (December 2016).

ATL-NSW-sTGC:

second test will be performed Friday 22th pm (QS1 Chili mod0) --> Gerardo

QL1 (Israel) will arrive beg. August (2 weeks of test) --> Ilia (Henso has all dimension) 

small TGC move in front of the source Wed 27th

 

CMS-CSC: third chamber (wed 27th, close to far end of the downstream wall).

 

ATL-NSW-sTGC and MM production chambers (find best position). Need dedicated meeting.

09:50 → 10:20 Plan for next test beam period

First discussion with RD51

I guess that we agreed that the two separate main/parasitic periods on Aug and Sept/Oct is not possible.

We will share therefore the two periods in a mode that we will define.

> correct. This is also my opinion.

BEAM:

It would be good if you can check and tell us if it is true what I'm writing

now:

"Any high intensity beam is fine with GIF++ if Goliath is off, i.e. high intensity muons beam in H4 with GIF++ in BEAM ON or high intensity pions beam in H4 with GIF++ in BEAM OFF (dump in) are fine."

> To my knowledge it is correct but I prefer to check with all users. I will confirm to you next Thursday. Is it ok? YES

 

GOLIATH:

Even if there is a preferred polarity, the operation in GIF++ with Goliath On is difficult.

At the end it is easier if we state like this and we can eventually later on investigate this more carefully.

> ok.
