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

Friday 27 Jan 2023, 14:00 → 14:50 Europe/Zurich

zoom (CERN)

ACTION TO BE DONE: 

• Ask Joel the delays for Hositrad 
• Ask Joel if the BPM clamps shall maintain fixed or sliding the cables 
• Carlotta and Fede discussion about re-machining strategy with Nanoker 
• STI shall re-machine the interconnect (2 modifications) + switch integration -> check why there is a mistake in the assembly -> Action STI
• Emilien and team will try to bend the cooling properly to let the shaft pass with a new tool
• PT100 not UHV accepted -> re-test with UHV cleaning from VSC and alcohol cleaning as done by the past (ongoing) 
• Tank washer to be machined and welded to install RF Screen rail 
• Cooling pipes re-bending without disassemble the TCLPX 

 

 

OTHER ACTIONS:

TCC:

• Julabo technician will arrive 2^nd of February 
• A test to remove water avec TCC test must be done 

 

BPM flanges:

• Tomography will be performed on the connectors at metrology lab next week
• Extraction done
• Re-machining of the flange for welding ongoing
• New BPM connectors delivered, next week for leak test

 

RF fingers:

• Fingers for S7
• 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
• Switch integration: drawing to be done
• TCTPXV review and modifications for serie: Emanuel working on it 
• Mechanical table procedure check: ongoing 
• Gabarit for cooling pipes production and assembly: ongoing
• Copper wedges for jaws posing during vacuum test (STI)

 

Assembly:

• TCLPX jaws under metrology to perform flatness measurements post-bakeout 
• TCTPXH jaws disassembled, and copper parts came back from metrology -> everything good 
• Tank delivered, mechanical tables, RF screen and RF collar and BPM cables and clamps installed, PT100 will be installed on the jaw and after that the cables in the tank, easier
• Interconnect to be remachined because holes and not fitting well

 

Procurement:

• Inermet blocks production ongoing, arriving at CERN beginning of March – 10th March
• CuCr1Zr delivered, under metrology then cleaning

 

Production MME: 

• RF fingers ongoing -> new delays from Emilien -> S7: perfect!
• Tank cover arriving mid-March (input from Emilien) then cleaning 
• Nanoker will re-machine the wrong blocks 

 

Update on planning: 

• Collimators shall be operational for July 
  • TCLPX prevision: September 
  • TCTPXH prevision: November
  • RF fingers, Inermet, TCC test bench are on the critical path 

 

Update for the serie:

• Create a tool to avoid DN300 to pull bellows during tank leak test 
• Reduce height and width of the clamps 
• 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 

 

14:00 → 14:10 Open actions

• Ask Joel the delays for Hositrad
• Ask Joel if the BPM clamps shall maintain fixed or sliding the cables
• Change the screws of the RF collar for serie production (Luca and team)
• Harmonize the tank thread for BPM clamps in M3 for the serie (Luca and team)
• Verify the thickness of the Ag deposit on the TCTPXH screws (Romain)
• Measurement of the CuCD blocks (Carlotta and Dylan)
• Take the BPM connectors at Joel office (Dylan)
• Ask the delays from Plansee (Federico)
• Emilien will sent the tanks metrology reports to Dylan
