MINUTE 59:
TCC:
- Financial issues between CERN and Julabo
- Waiting for Jean-Marc updates on soft and to get back the date from TCSPM LS2
- PT100 connectors installed – Régis will check to order the tubes connectors
BPM flanges:
- Test of connectors only are all good, so the problem does not come from connector before welding
- The welding process from MME is the same as usual and it is the thinner parameters used.
- Hypothesis: local heat can create a leak on the connectors
- The connectors will be inspected before welding and Joel will order a new batch
- A discussion between Emilien, Federico and Stefano S. will take place
- Ositrade looking at the drawing and offer ongoing
- Sub D-9 connector to be ordered by Jerome
RF fingers:
- Hybrid version between TCS and TCSPM: longer than TCSPM to avoid stress, additional screw to avoid stress on welding + lyre for flexibility (design TCSPM with TCS length)
- Update: adding shorter screws et deeper threads
- Emilien is proposing mid-March – Romain is looking for firms to do these fingers
- Rhodium is stayed on the part (chemical analysis attached to the INDICO)
- Adjust length of the RF fingers testbench
- Warning about the limitor and get the adequate space for fingers
- Weld the testbench support to limit mechanical play
Design:
- RF fingers:
- DN300 flanges with pinch-off: waiting the CDD from VSC
- Jaw flatness measurement tool -> give the CDD to Dylan for the tooling list
- TCLP, TCSPM, TCTPM folders: not started
- Post-proto modifications regarding Dylan’s Excel: ongoing for jaws, done for mechanical table
- Shims for IP1 or taller feets: ongoing
- Cover update regarding CZ5: ?
- Switch integration: ongoing
- TCTPXV review and modifications for serie: will be reviewed WP5.2 14th of November
- Mechanical table procedure: ongoing
- Gabarit for cooling pipes production: ongoing, wait for comments
- Extremity RF fingers new design (ok regarding stress to reduce length): not started
- Copper wedges for jaws posing during vacuum test (STI)
- Check if we can use the same jaw design for TCTPXH as TCLPX (1 week)
- Taperings drawing done
Jaw assembly:
- TCLPX waiting for TCC
- TCTPXH disassembled and copper parts under metrology control for additional measurements
Absorber materials update:
- Blocks arriving mid-November then metrology and TT
- Check ongoing by Carlotta for a tomography of the blocks
Production MME:
- Tanks under control with new references
- RF screen rail electropolished, metrology done
- LHCTCLPX__0142 transition support ongoing
- RF fingers production
- 2 references for tank missing
- RF collar modification
Production STI:
- Jaw flatness measurement tool: ongoing
- Levelling parts: finished
- Remaining feets components: ongoing
- Adaptation for vireur: ongoing
- Transitions and pinch-off: not started
- TCC rack: done
- Lifting ears: not started
Update on planning:
Update for the serie:
- Having a defined and precise mechanical play to let the RF fingers sliding properly
