MINUTE 69 :
URGENT ACTIONS:
- TCC test to be re-launch in automatic with good values of flow and outlet temperature and JMQ will correct the launching condition of the TCC
- Inermet validation phase ongoing – 11th of April
- TCLPX insertion with 1 pin
- Dylan will add 8 days for BPM flanges UHV validation after the production
- Gregory will check to produce 1 short NEG Cartridge, otherwise ok with the integration to put a long one (50mm more)
- Validate the flexibles : Different manifold regarding L or R is ok regarding the spares ? Standardize L and R length ? To be confirmed with FX
- RF fingers first cycling finished at 25k cycles -> under measurement (silver coating thickness remaining)
- MME production of flanges, RF components, flanges
OTHER ACTIONS:
TCC:
- Official cycles to be performed once the TCLPX will be available
- JMQ will test automatic cycles.
BPM flanges:
- 4 new flanges under production to re-launch test
- 1 test flange with passive cooling during welding has been validated
RF fingers:
- Cycling finished, under measurements
- We can assemble the RF component after tank closing if necessary
- Romain is preparing a report
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
- TCTPXV review and modifications for serie: Emanuel working on it
- Mechanical table procedure check: ongoing
- TCLM masks
- Copper wedges for jaws posing during vacuum test (STI)
Assembly:
- TCTPXH waiting for blocks
- Tank Screen rails to be re-assembled
- Tank cover to be test-assembled
- TCLPX to insert playing with the fixing plate and then final assembled
- Luisa gives to Dyln the torque to be applied on the tensionning plates
Procurement:
- Inermet blocks arrived at CERN, under validation for 11th of April
- Nanoker will re-machine the wrong blocks -> Dylan will prepare the blocks for Carlotta
Production MME:
- Flanges to machine: 2xLHCTCLPX_T0129 + 2xLHCTCLPX_T0118 + 2xLHCTC__X_T0116 + 2xLHCTC__X_T0118 -> flanges for proto S21, mock-up S24 with metrology + cleaning
- BPM flanges : S14 machining - S15/16 : FE – S17 leak test – S17 delivery
- Cooling circuit : 3 received from ELI industries – little correction on a BPM – No delivery date to give for the moment (remaining steps : machining, metrology, brazing, cleaning, leak test, pressure test)
- RF collar : Priority -> next Wednesday if Luca gives the C1 on Thursday
- CAP + spacers + other collar (with electropolishing + rhodium) : 14th of May for STI, Emilien will give us delivery dates when the C2 will be performed
- RF fingers for tests : 6 fingers under detentioning treatment, Romain asked to silver coat only 2 of them (5 and 15um) – Waiting for instruction for the 4 others fingers.
- RF fingers for installation in the proto : Delivery dates when we get the confirmation from STI
Update on planning:
- Collimators shall be operational for July.
- RF fingers, Inermet, BPM flanges, and RF components on the critical path
Update for the serie:
- Change a bit the design of the RF fingers (with the little screws) -> Romain will do a proposal
