Minute 43 :
Plug-ins
- Asset creation
- Order sent to Helix, supplier to award the contract
Mechanical table assembly:
- Assembly procedure finished
- Cycling test will begin next week on 1 TCLPX and on 1 TCTPXH
- First torque test under load done and good
TCC:
- Update next week with CEM for the software
- Meeting with a chiller bath supplier to give them our requirements
- Specification ongoing
- Check for design modification and cleaning of the posing surface
- Carlotta performed a first model, Ansys benchmarking ongoing to launch new simulations. What is important is to confirm the parameters of the first analysis and the parameters that have an influence on the results. But also find a characteristic time mini acceptable with the TCC
Design:
- Washer to protect bellows during FE welding design to finish
- Jaw lifting tool designed and to be produced by MME
- Jaw and tank procedure ongoing
- Ears for lifting of the collimators with a slope: 19mm difference -> stay with no slope and test it during mockup tests
Absorber materials update:
- CuCD blocks under metrology
- Inermet taken by STI for assembly – Metrology not needed because no appearing and very good flatness
VSC:
- Waiting for costs and delays
- Check the quantities needed : 2 total assembly + 4 bottom parts
- Design modifications due to holes position – 3D to be sent to Luca beginning of next week
- Bellows next week on Friday ready for RGA (Design may change due to tank extremities, to be followed)
- Jacket ordered with ions pump : 6kCHF
Production:
- Shaft on Monday from TT, then last machining step
- Contouring tank plate ongoing
- RF contacts to weld
- First batch of jaw parts sent to STI
- Beam pipes done, then length cutting, then welding and carbon deposite
- BPM flange at 40/30 for leak tests for the repaired ones, now only 1 leak, to be repaired
- Cooling pipes ok even with 0.2mm of flatness on the border. Brazing next week
- Cu parts 1 month left with priority on TCLPX parts to begin assembly before, but staff absent and CNC fail, need to be repaired
Additional screws:
- Meeting to Schaeffler production site, they proposed us preloaded screws with 5N.cm
- We now have 4x3 screws : Rollvis, Schaeffler, Ewellix, and maybe Moog
Graphite tapering:
- Metrology good, but not for 28.9mm of height, and not for the form tolerance : ok for the functionality but to be checked with impedance team
Update on planning:
Update for the serie:
Others:
- RGA final report almost done
- Tools for flatness measurement: check the compatibility (point 4 or 132)
- Production of 4 jaw lifting tools for STI and VSC
