ACTION TO BE DONE:
- Ask Joel the delays for Hositrad -> June.
- Ask Joel if the BPM clamps shall maintain fixed or sliding the cables -> Shall be sliding in the clamp -> Action for Luca to update the design.
- Ask the delays from Plansee (Federico) -> End of March
- Dylan call Emilien when TCLPX jaws ready for untightening
- STI shall re-machine the interconnect (2 modifications)
- Emilien and team will try to bend the spare cooling properly with a tool -> Did not worked -> Planning update by Dylan.
- Luca and team shall sign in C1: Interconnect, Flanges
- Romain and Emilien shall put a report on the indico regarding RF fingers and tomography.
- Romain will contact C. Garion that is used to design RF fingers for other application to get advice.
- Emilien will give new delays for RF fingers (since wrong dimension + surface treatment)
- Emmanuel will perform the modification of the switches support to remove the pins.
- Luca shall find the reference available on website for the TCTPXH washers.
OTHER ACTIONS:
Switch integration:
- New version with new support to maintain switches, screws changed, pin to remove because we set in position after assembly.
- To be produced by STI -> The blue support will be 3D printed.
TCC:
- TCC preliminary test beginning with fake jaw.
- A test to remove water avec TCC has been performed.
BPM flanges:
- Tomography done, the welding of the connector itself is good, we cannot see the inside (ceramic) -> Difficult to give a conclusion here (check attached report).
- 4 new flanges under production to re-launch test -> A discussion with AP and STI and BI will be organized.
RF fingers:
- Wrong curt from chemical team, new ones under chemical cut.
- Romain performed several treatments (tri-acide, electropolishing, Subu) with M. Thibert, Subu seems the best solution (check attached report). -> 800CHF for 20 fingers.
- Romain will check if it is necessary to do silver plating, and if yes, which thickness.
- Adjust length of the RF fingers testbench.
Design:
- TCLP, TCSPM, TCTPM folders: not started
- Post-proto modifications regarding Dylan’s Excel: ongoing for jaws, done for mechanical table, almost finished for feet
- Switch integration: drawing to be done
- TCTPXV review and modifications for serie: Emanuel working on it
- Mechanical table procedure check: ongoing
- Gabarit for cooling pipes production and assembly: ongoing
- Copper wedges for jaws posing during vacuum test (STI)
Assembly:
- TCTPXH jaws re-assembled without blocks to do a fake insertion in the tank.
- Tank sub-components assembled.
Procurement:
- Inermet blocks production ongoing, arriving at CERN End of March
Production MME:
- Tank cover arriving mid-March (input from Emilien) then cleaning.
- Nanoker will re-machine the wrong blocks
Update on planning:
- Collimators shall be operational for July
- TCLPX prevision: Mid-October
- TCTPXH prevision: Mid-November
- RF fingers, Inermet, BPM flanges, TCC test bench are on the critical path.
Update for the serie:
- Create a tool to avoid DN300 to pull bellows during tank leak test
- Reduce height and width of the clamps
- Check to put an elastic element as TCLPX for TCTPXH and avoid overlength of the blocks
- Define a probe cable length for serie with Jerome
