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

Friday 15 Jul 2022, 14:00 → 14:50 Europe/Zurich

zoom (CERN)

Nanoker meeting report

MINUTE 48

Mechanical table assembly:

• Cycling launch to 10k

TCC:

• The TCC test bench burned
• Action: have as soon as possible a quotation for a chiller
• Do not touch in any case the TCC because we need the data of LS2 collimators (TCSPM and TCPPM)
• Steven received the inputs and specification to design a new posing system for the jaws
• Carlotta needs thermocouples at the inlet and outlet of the jaw circuit

Design:

• Jaw lifting tool produced by STI
• Jaw and tank procedure to update in 4 weeks

Absorber materials update:

• Update second Nanoker visit : if we have them W39, this is good. We can release the CuCD lateral face flatness, it can avoid grinding on it. Check report 2757736

VSC:

• Waiting for costs and delays
• Design modifications due to holes position: invert the male and female part because the pins are too long : ok for protos
• Check an arrangement between STI and VSC to order one time for all the components
• 15^th of July reception of jackets
• Prod of autoregulated testbench for the serie

BI:

• EDMS 2419688 for the ABCD convention: same as CEM
• A discussion is needed to check with CEM the viability of the proposition
• ABCD stay fix and thanks to that we know which BPM is on which jaw and upstream or downstream

Production:

• Mistake on the cooling pipes : Wrong diameter in the beginning/ end of the pipes -> solution is to add an longer fitting ring, thanks to that we can use the leak test tool
• Bellows on shaft end by Tuesday, then cleaning and FE end of next week, welding on tank in 3 weeks then leak tests
• Tank under EB welding + re-machining of the bellow shaft next week
• Jaw copper parts TCTPXH n.1 finished and the rest before the Fabrice’s holidays
• BPM flange at 40/30 for leak tests for the repaired ones, now only 1 leak, to be repaired
• Manifold from STI almost done + lot of other parts

Additional screws:

• We now have 4x3 screws: Rollvis, Schaeffler, Ewellix, and maybe Moog

Graphite tapering:

Update on planning:

Update for the serie:

• Remove the surfacing of the bellow for the serie, this is useless
• Be aware of the penetration of the welding in the drawing, this is written 3 and 6mm but this is 6mm everywhere
