5 CTF3 CLEX day July 2006

Next steps: 2006

• Fully commission Delay Loop

• Separate Linac from rest of machine

• 30 GHz power testing

• Construction of CLEX building

• Install and commission Combiner Ring

Combiner Ring and TL1:Optics: INFN Magnets: BINP/CERN/Lure/CIEMAT/

INFN Power supplies: CERN RF deflectors: INFN Septa: CIEMAT Kicker: CIEMAT/CERN pulser: CIEMAT/CERN 3 GHz source: CERN Controls: CERN BPM electronics: LAPP / CERN Vacuum chamber + BPM: INFN

In spite of some difficulties, we expect the Combiner Ring to be finished in 2006

12 CTF3 CLEX day July 2006

Tests with 2-beam test stand

a) condition and operate a PETS structure up to the nominal output power (640 MW, 70 ns). The test structure will have the same geometry as a CLIC PETS but only be longer to be able to generate the same power levels with a lower current beam - 30 A rather than 160 A

b) operate CLIC accelerating structure at nominal parameters

c) acceleration with probe beam (single or few bunches); verify fields, power

d) measure the effect of rf breakdown on the drive and probe beams. The measurements are crucial for determining the required breakdown rate for CLIC components.

e) demonstrate operation of a CLIC module which consists of four accelerating structures driven by a PETS.
