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

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 KEK11.4 GHz Loads (x4) for KEK 2 with KEK
flanges and 2 with SLAC flanges– Rf design done – Mechanical design done– Call for tender under way– Fabrication: by end of October– Supply of the material: shipped to CERN, not
received yet
SLAC flanges: pieces available at CERN, brazing and assembly by end of July
