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

Friday 10 Mar 2023, 14:00 → 14:50 Europe/Zurich

zoom (CERN)

ACTION TO BE DONE: 

• STI will re-assemble TCTPXH for good positioning of the sttifeners.
• Dylan will send TCLPX jaws screen to Carlotta and Luisa.
• Emilien shall put a report on the indico regarding tomography.
• Luca shall update reference available on website for the TCTPXH washers.
• Dylan will send data to Luisa for simulations.
• Gabarit should be send to Emilien as soon as possible.
• Romain will cut M4x35 A4-100.
• Emilien will bring the tank covers next time (TCLPX bending slot).

 

OTHER ACTIONS:

TCC:

• Several test ongoing to validate the testbench and for Luisa and Carlotta (with all the data).
• Some data shall be clarified between Dylan and JMQ.
• JMQ will test automatic cycles.

 

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. 1 flange ongoing in machining to test welding with passive cooling with TIG. SubD9 ordered by Jerome.

 

RF fingers:

• Romain launch silver plating: 2x5mm, 1x10mm, 1x15mm. EBW ongoing.
• 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
• TCTPXV review and modifications for serie: Emanuel working on it 
• Mechanical table procedure check: ongoing 
• Gabarit for cooling pipes production and assembly: ongoing
• TCLM masks 
• Copper wedges for jaws posing during vacuum test (STI)

 

Assembly:

• TCTPXH jaws re-assembled without blocks to do a fake insertion in the tank.
• TCLPX waiting for re-bending.

 

Procurement:

• Inermet blocks production ongoing, arriving at CERN End of March.
• Nanoker will re-machine the wrong blocks 

 

Production MME: 

• Tank cover arriving mid-March (input from Emilien) then cleaning.
• Flanges to machine: 2xLHCTCLPX_T0129 + 2xLHCTCLPX_T0118 + 2xLHCTC__X_T0116 + 2xLHCTC__X_T0118
• BPM leaking flanges to solve with passive cooling. 
• RF fingers 

 

Update on planning: 

• Collimators shall be operational for July. 
  • TCLPX prevision: Mid-October 
  • TCTPXH prevision: Beginning of November
  • RF fingers, Inermet, BPM flanges, TCC test bench are on the critical path. 
  • Cooling for April

 

Update for the serie:

• 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. 
• Put sliding contact for BPM clamps.
