6 Transfer Line TL2 Preliminary design from LN Expression of interest and additional design studies from CAT/Indore Sufficient number of quadrupoles and sextupoles already available? Bend magnet design (CERN) Matching to required Twiss parameters in CLEX from quads in bunch compressor and in straights (x = `x = y = `y = 0) CLEX beam axis x = `x = y = `y = 0 Beam dump? inal horizontal displacement, bunch compression with tunable R56 CR beam axis Somewhere 0.8 in this m length: Vertical displacement, achromatic system (small positive R56) Straight space for tail clipper ( ~ 4m) CT3 coll meetg 2005 CLEX H. displacement, achromatic system (small positive R56) 6

8 CLEX building Building Status Inside dimensions specified to be 40 x 8 x 2.75 m No pillars inside building! Preliminary construction design and cost estimate completed raft specification for infrastructure requirements (electricity, cooling, ventilation, ~700 kw electrical power dissipated in various components) Equipment gallery 20 x 8 x 3.55 m Schedule Construction finished by end 2006 CT3 coll meetg 2005 CLEX 8

9 loor and Beamline Heights ue to difference in construction technique CLEX floor is 50 cm lower than combiner ring building and B Linac building Beam height above floor B Linac, delay loop, TL1 and combiner ring 135 cm 135 cm + 50 cm=185 cm seems to much Vertical bends needed in TL2 Beam height drive beam in CLEX 135 cm Probe beam at 125 cm to allow crossing of beam lines? What s best for two beam test stand? CLEX 50cm B Linac CT3 coll meetg 2005 CLEX 9

10 CLEX gallery Enough space for all power supplies, vacuum, controls and beam diagnostics racks needed for CLEX beam lines Space for two S-band modulators and klystrons for probe beam Neighboring CT2 gallery has space for one or two more modulators and klystrons and for more electronic racks (i.e. for 30 GHz receivers for two beam test stand and drive beam test beam line) LIL Galery CT2 Galery Racks 0.6x0.9m 2.3m m Modulator Modulator 2.4m 8 m 20 m arrangement of racks and modulators in CLEX-G CT3 coll meetg 2005 CLEX 10

14 Beam-Lines Probe beam Preliminary design from APNIA & LAL Problems: overall length, beam loading, laser configuration TBL Preliminary design for quadrupole magnets (CERN) transferred to CIEMAT esign of support tables with X/Y movers / CIEMAT esign considerations for PETS (I. Syratchev and. Schulte, PAC 05), CIEMAT BLM s NWU Chicago Expression of interest for BPM s by IIC and TU Barcelona Two beam test stand Uppsala University ITB draft proposal from John Adams Institute UMP UMP UMP UMP ITB UMP TBL 30 GHz Test stand UMP CT3 coll meetg 2005 CLEX LIL-ACS 1m wide passage all around Probe beam injector UMP LIL-ACS 14
