CLIC Collaboration Meeting Agenda - Production and Testing Updates

DESCRIPTION

This document outlines the agenda for the CLIC collaboration meeting held on July 4, 2008. Key topics include the status of the production and test program at CERN, KEK, and SLAC; testing of PETS; and design updates for quadrants and disks. Discussion points also cover the pulse compressor for Nextef at KEK, agreements on costs with SLAC, and procedural decisions regarding the disk version. Additional details on the production timeline, assembly tests, and environmental checks for components are provided.

  1. CLIC structure collaboration meeting G. Riddone, AB-RF 2008.07.04

  2. 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

  3. Status – x-band ac. structures

  4. 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

  5. C10 damped structures Cern agreement

  6. CLIC vg1 structures

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

  8. 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

  9. 11.4 GHz Loads (x4) for KEK 11.4 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
