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

Friday 2 Dec 2022, 14:00 → 14:50 Europe/Zurich

zoom (CERN)

MINUTE 58:

 

TCC:

• Financial issues between CERN and Julabo
• Waiting for Jean-Marc updates on soft and to get back the date from TCSPM LS2
• PT100 connectors installed – Régis will check to order the tubes connectors 

BPM flanges:

• 3 Flanges ok – 2 remaining
• Test of connectors only are all good
• Plan B : production of flanges to Ositrade in parallel

Design:

• RF fingers:
  • Hybrid version between TCS and TCSPM: longer than TCSPM to avoid stress, additional screw to avoid stress on welding + lyre for flexibility (design TCSPM with TCS length)
  • Update: adding shorter screws et deeper threads 
• DN300 flanges with pinch-off: waiting the CDD from VSC 
• Jaw flatness measurement tool -> give the CDD to Dylan for the tooling list
• TCLP, TCSPM, TCTPM folders: not started 
• Post-proto modifications regarding Dylan’s Excel: ongoing for jaws, done for mechanical table
• Shims for IP1 or taller feets: ongoing
• Cover update regarding CZ5: ?
• Switch integration: ongoing
• TCTPXV review and modifications for serie: will be reviewed WP5.2 14^th of November 
• Mechanical table procedure: ongoing 
• Gabarit for cooling pipes production: ongoing, wait for comments 
• Extremity RF fingers new design (ok regarding stress to reduce length): not started 
• Copper wedges for jaws posing during vacuum test (STI)
• Check if we can use the same jaw design for TCTPXH as TCLPX (1 week) 
• Taperings drawing done

Jaw assembly:

• TCLPX waiting for TCC
• TCTPXH disassembled and blocks to Carlotta

Absorber materials update:

• Blocks arriving mid-November then metrology and TT
• Check ongoing by Carlotta for a tomography of the blocks 

Production MME: 

• Tanks under control with new references
• RF screen rail electropolished, metrology done
• LHCTCLPX__0142 transition support ongoing
• RF fingers production 
• 2 references for tank missing
• RF collar modification

Production STI: 

• Jaw flatness measurement tool: ongoing
• Levelling parts: finished
• Remaining feets components: ongoing
• Adaptation for vireur: ongoing
• Transitions and pinch-off: not started
• TCC rack: done
• Lifting ears: not started
• Adjust length of the RF fingers testbench + warning about the limitor and get the adequate space for fingers + welding on support to limit mechanical play

Update on planning: 

 

Update for the serie:

• Having a defined and precise mechanical play to let the RF fingers sliding properly
