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 11^th 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) : 14^th 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
