2 more PT100 good but less good than the 2 firsts -> We can continue the assembly of TCLPX
Gregory check with Emilien to produce 1 short NEG Cartridge
Oblongs on the drift tube will not be changed -> Emilien sent it to waterjet cut
OTHER ACTIONS:
TCC:
TCTPXH on the testbench on Monday and Tuesday
BPM flanges:
All welded – Leak test on Monday
RF fingers:
RF fingers third cycling finished -> finger support broke around 10 and 12k cycles at several points. Check with Luca and Fede to maybe have only 1 opening. Annealing make the stripping impossible. The tests will determine the Ag thickness + annealing or not.
TCTPXV review and modifications for serie: Emanuel working on it
Mechanical table procedure check: ongoing
TCLM masks: not started
Copper wedges for jaws posing during vacuum test (STI)
Assembly:
TCLPX to be be inserted
TCTPXH under vacuum test next week after TCC tests
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)
CAP + spacers + other collars (with electropolishing + rhodium): 6th of June – Emilien receive the material. It may be interesting to use 304L instead of 316L.
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, and RF components on the critical path
Update for the serie:
Change a bit the design of the RF fingers -> Romain will do a proposal
