  1. CLEX day 2006 Introduction G.Geschonke CERN CTF3 CLEX day July 2006

  2. CTF3 programme 2005 2004 Thermionic gun DL Linac CR 2006 CLEX2007-2009 building in 2006 Photo injector / laser tests from 2006 TL2 2007 30 GHz production (PETS line) and test stand On schedule so far CTF3 CLEX day July 2006

  3. Delay Loop latest news one of three buncher cavities CTF3 CLEX day July 2006

  4. Two-beam 30 GHz power production in CTF3 High-gradient test stand, CTF2 High-power transfer line CTF3 linac PETs branch 30 GHz work recent Cu structure presently CLIC parameters are reviewed, probably frequency and acc. gradient change CTF3 CLEX day July 2006

  5. Next steps: 2006 • Fully commission Delay Loop ü • Separate Linac from rest of machine ü • 30 GHz power testing ü • Construction of CLEX building ü • Install and commission Combiner Ring Combiner Ring and TL1: Optics: INFN ü Magnets: BINP/CERN/Lure/CIEMAT/ INFN ü Power supplies: CERN ü RF deflectors: INFN ü Septa: CIEMATü Kicker: CIEMAT/CERN ü pulser: CIEMAT/CERN ü 3 GHz source: CERN ü Controls: CERN ü BPM electronics: LAPP / CERN ü Vacuum chamber + BPM:INFN ü In spite of some difficulties, we expect the Combiner Ring to be finished in 2006 CTF3 CLEX day July 2006

  7. Next steps: 2007 Optics India ? Magnets: CERN, Celsius, CIEMAT, Vacuum system: India ? 50 m alu chamber, shielded bellows + pump ports, BPM pick-ups and screens: CERN Vacuum pumps and controlCERN Power supplies: CERN BPM electronics : LAPP ? TL2 * 2007 CERN ? TL2 (2007) CTF3 CLEX day July 2006

  8. CLEX building Construction during 2006 installation of equipment from 2007 - 2009 8 m wide, 40 m long partly covered by klystron gallery Status: Building layout defined construction started 2006  Hans Braun CTF3 CLEX day July 2006

  9. CLEX 24.5.2006 3.5.2006 10.7.2006 CTF3 CLEX day July 2006

  10. Project status CLEX Building: CERN 2-Beam Test Stand: Beam dynamics, Magnets, vacuum, Beam Diagnostics; Uppsala University DUT + RF equipment: CERN TBL Design: CERN Benchmarking experiments : CERN Magnets and magnet movers: CIEMAT Power supplies: CERN Beam Diagnostics: Spain ? NW University Illinois Vacuum system CERN PETS: Prototype CIEMAT, Series ? Probe Beam Dapnia / LAPP / LAL CERN Instrumentation Test Beam (not presently in base-line project) Great Britain ? Installations should be able to be operated by the operations/commissioning team ! CTF3 CLEX day July 2006

  11. Variable Power Splitter RF Power from PETS Directional couplers Ion Pump Cooling Water Faraday Cup Accelerating Structure Tank RF Loads ‘Typical’ 30 GHz high-power test stand Pets Accelerating structure CTF3 CLEX day July 2006

  12. 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.

  14. Photo Injector Status: RAL laser advancing LAL RF gun cavity advancing CERN photo cathode activities on schedule. 85 MV/m acc. field 5 MeV Phase 1: Test in CTF2: From 2007 onwards Laser in “old” laser room above CTF2 Phase 2: Gun in CTF3: earliest spring 2008 Laser in CTF2 CTF3 CLEX day July 2006

  15. Klystron/modulator : ? Laser In “old" laser room above CTF2: from mid 2006 In CTF3 earliest beginning 2008 Califes installation ? Commissioning in parallel with TBTS and PETS tests (2008) Probe Beam Planning summary: CR install: fall 2006 CR Commissioning: 2007 CLEX: building ready: end 2006 ready to install equipment: Mid June 2007 Klystron gallery: building ready: March 2007 ready to install equipment: Mid June 2007 TL2: Install 2. half 2007 TL2*: Install end 2007 Beam in CLEX : from March 2008 onwards Two-Beam test stand : First beam as early as possible: April 2008 TBL : goal first tests in 2008 Goals for 2008: PETS power / operate accelerating structure / Probe beam commissioned CTF3 CLEX day July 2006

  16. Expected this evening Definition of: Who does what from where to where interfaces, engineering details, infrastructure integration Planning updated or confirmed BPM strategy, read-out electronics ? CTF3 CLEX day July 2006
