    WP5.2 - TCLPX/TCTPXH Prototypes Production Follow-up

    CERN
      • 14:00 → 14:30
        Ongoing actions 30m

        MINUTE 70 : 

        URGENT ACTIONS: 

        • 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.
        • Romain is preparing a report 

         

        Design 

        • TCLP, TCSPM, TCTPM folders: Ongoing. 
        • Post-proto modifications regarding Dylan’s Excel: Ongoing 75%
        • 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
