CERN
URGENT ACTIONS:
- TCC test to be re-launch in automatic with good values of flow and outlet temperature
- Emilien will bring the tank covers next time (TCLPX bending slot).
- Luca will send the RF components to re-machine due to the new design, RF collar in priority
- Inermet validation phase ongoing – 11th of April
- Shafts relative position in metrology -> find is the mistake in the assembly come from the tank, the jaws, the mechanical tables or the machining tools
- RF screen to be disassembled
- New TCLPX bending of the circuit to insert properly in the tank
OTHER ACTIONS:
TCC:
- Official cycles to be performed once the TCLPX will be available
- Some data shall be clarified between Dylan and JMQ.
- JMQ will test automatic cycles.
BPM flanges:
- 4 new flanges under production to re-launch test
- 1 test flange to try passive cooling
RF fingers:
- Cycling ongoing without annealing and with 5um silver coting. Annealing for the next fingers.
- Waiting for C1 on RF components
- We can assemble the RF component after tank closing if necessary
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 to be inserted without blocks
- Tank Screen rails to be disassembled
- TCLPX to re-bend
Procurement:
- Inermet blocks arrived at CERN, under validation
- 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.
- RF fingers, Inermet, BPM flanges, and RF components
Update for the serie:
- LHCTC__X_T0001 aligner la surface de posage pour tournage coaxialite et tolerance sur piece T0006
- LHCTC__X_T0002 triple contact a enlever car hyperstatique, risque de mauvais emmanchement pour soudage. + axe pas centrer sur le dessin.
