1. ELENA – Vacuum chambers and vacuum activities
IIC meeting
G. Riddone (contribution from G. Bregliozzi, R. Kersevan,
A. Mongelluzzo, A. Sapountzis, A. Sinturel. M. Thiebert)

2. Vacuum chamber productions
EN-MME
LNR Dipole vacuum chambers
LNI Y-vacuum chamber
LNI quadrupole vacuum chambers
LNI dipole vacuum chambers
LNR inj-ejection vacuum chambers
LNS: AD_VCPAB AD_VCPAC0001
Trinos
All other straight chambers for LNR, LNE00, LNE50, LNI and LNS
To be noticed that 4 LNE50 chambers need management green light before launching the production (EN-MME or Trinos): VCDCU/CX/CW/CV

7. Bake-out equipment LNR dipole Kickers
Jackets are installed on all the chambers
Kickers
Jackets are installed
BPM and other chambers in the magnets
Wrapping according to magnet availability
Standard elements
Ion pumps, gauges, chambers: wrapping on-site after vacuum tests

8. NEG coating LNR dipole vacuum chambers Scraper bellows:
#1: LNR dipole chamber # 1 (NEG completed) was installed with supports on two dipole magnets to check availability space between coils and bake out jackets.
#2: NEG coating done, masked bellows and sleeves, no peel off, transport to B113 for acceptance tests
#3: NEG coating in W23
#4 to 6 : NEG coating will follow W24, 25 and 26
Scraper bellows:
1 bellows with NEG successfully tested (no peel-off)
1 bellows NEG W23
LNR chambers TRINOS
RUN #2 successfully coated, no peel-off at bellows or welding
RUN #3 (Week 23)
Y-chambers x3: NEG coating W24 to W26

9. NEG coating PU SCHOTTKY (Responsible Jorge Sanchez Quesada)
4 chambers received (weight ~80 kilos each, very fragile)
Optical inspection of the 4 chambers have dust, projections, metallic shavings, oxidation, scratches and white spots. Proposed actions-> to be discussed
BPM for Tune (Responsible: Joel Albertone)
After the acceptance test there is peel-off (dust-like).
The electrodes were coated in another lab than the vacuum tanks.
Unable to confirm by eye if the peel-off is coming from the chamber only or/and the electrodes Proposed actions-> to be discussed
Try to detect Ti,Zr,V on the vacuum chamber with a portable XRF
If there is NEG on the chamber, manufacture new electrodes
If there is no NEG on the chamber, in addition the electrodes, strip the NEG from the chamber (if possible) and/or manufacture new chambers.

10. Acceptance tests

Underway
BTV tank with NEG
Kicker tank with extra pumps: 1 Capacitorr D2000, 1 Capacitorr D3500,
In the pipeline
Y- Chambers (2+1): available for testing end of June, W27
LNR dipole chambers: 1 chamber per week W24 to 29.
SEM chambers:
assembly to be tested with vacuum chambers W24-25
one vacuum chamber alone after cleaning to be tested W23-24
Trinos vacuum chambers:
set#2 with NEG W23 (1 chamber only will be tested)
set#3 with NEG W24 (1 chamber only will be tested)

11. Installation Focused on the sector LNI-LNE and LNR
40, 45% of the installation of those sectors is done.
We wait for survey team to align the dipoles to continue the installation in LNR 40.
We wait for EN-MME to re-machine the support plate of the LNI.ZQNA.0050 to connect last part of LNI.
We wait for one more SEM tank to complete sector valve installation in LNE00.
