agenda
Agenda
  • Status of the production and test program (CERN, KEK, SLAC)
  • Testing of PETS (CERN, SLAC)
  • Design of quadrants and disks (KEK)
  • Pulse compressor for Nextef at KEK

CLIC vg1 quadrant damped TD18_vg2.4_quad#3
  • For the preparation decision to follow the same procedure as SLAC for the disk version
  • Done at CERN: dimensional control, Rf check, cleaning, assembly test  shipping to SLAC on 24.06
  • To be done at SLAC: heat treatment, brazing of the cooling pipes, SEM, baking, final assembly, rf checks
  • CERN agreement on additional SLAC costs
  • Question: Tuning (yes/no)  decision postponed after heat treatment
    • Heat treatment at CERN done for #1 (same cycle as for SLAC)  then rf check, dimensional control, tuning test

Status - PETS

Received bars for 12 GHz test  Dimensional control: OK (+/- 10 mm)

pets 11 4 ghz w o damping mat
PETS 11.4 GHz w/o damping mat.
  • Done at CERN before shipping to SLAC
    • Dimensional control of two bars
    • Brazing and preparation of the couplers
    • Assembly test
    • Rf check
    • Cleaning of all pieces
    • EB welding of the bars
    • Tank and couplers assembly
    • Final EB welding: 07.07
    • rf test + UHV test

PETS shall be shipped to SLAC in CW28 at the latest

11 4 ghz loads x4 for kek
