WP5.2 - TCLPX/TCTPXH Prototypes Production Follow-up

Friday 9 Sept 2022, 14:00 → 14:50 Europe/Zurich

zoom (CERN)

Minutes of Today's discussion about CuCD status:

 

There are 9 CuCD Blocks at CERN for which three geometrical families are got. 

6 of these blocks have recently been through Thermal treatment and UHV acceptance tests. The total outgassing rate is good (3.10-9 mbar/l/s). However, a peak of Ar is observed (2.10-8 mbar/l/s not coherent with the total outgassing rate!)and expected to not come from an internal air leak but rather a physiscal presence of Ar coming from the CuCD process. The CuCD process in question in the Thermal treatment at CERN.

Action for Carlotta to check how was performed the venting.

Then these blcoks shall be available around the 26/09 for assembly on the 1st TCTPXH jaw.

 

5 other CuCD blocks are at VARAS. They'll be shipped to Nanoker on the 19/09. A metrology will follow at Nanoker. CERN shall receive the metrology reports before the blocks shipement to CERN, planned on the 26/09. Metrology, TTH and UHV test are then planned.

 

5 last blocks are expected to be shipped to CERN before mid of October.
