MINUTE 51
TCC:
- Order to Julabo for a new chiller bath with control box allowing CEM to monitor and extract data
- Arriving 19th october
- Do not touch in any case the TCC because we need the data of LS2 collimators (TCSPM and TCPPM). Jean Marc is checking for updating the software part and Christophe possesses few additional thermocouples
- TCC rack designed and in production
Design:
- Next jobs are : finish the levelling, design of DN300 flanges with pinch-off, jaw flatness measurement tool -> give the CDD to Dylan for the tooling list
Jaw assembly:
- What is the M4 tool screw: just a normal screw
- Thickness of the clinquant for assembly -> no importance, it is just to avoid clashing with cooling pipes
- The RF collar X244 don’t need rhodium coating
Absorber materials update:
- “I discussed today with Nanoker, and on Monday (26/09) they will receive 5 blocks machined from VARAS. They will perform metrology and send us the results before shipping. 3 additional blocks will be ready to be shipped in VARAS on Monday/Tuesday, and the last plate will be produced in the same days. They think to conclude the shipping to CERN in 2/3 weeks. I discussed today with Gregory, and the new test repeated on CuCD after the additional thermal treatment is much better. The internal leak is now approaching the acceptance. However, we will have a dedicated discussion with him and Giuseppe on Monday morning before giving the greenlight to Nanoker.”
VSC:
- Combitac connectors around 10kCHF/ unit – this is expensive – Tests of the homemade connector by Luca to test, this is maybe a tricky connector – Last possibility is connection by robots.
- Check an arrangement between STI and VSC to order one time for all the components
- Check with VSC the number of flanges and if they can give us the transition for storage/ mock-up etc
Production:
- H21 and 20 metrology and cleaning
- H22 cleaning
- X130, 131 and TCTP36 cleaned
- Find H29
- Leak test discussion at 40/30 with Emilien on Monday
- RF fingers spare under cleaning
- Tank finished on Tuesday then cleaning for both and leak test
- 4 DN300 flanges ok but 2 has a 0.2mm radius instead of 0.1mm but this is not a functional issue
Additional screws:
- We now have 4x3 screws: Rollvis, Schaeffler, Ewellix -> 1-month delays for both (30 september)
