PRESENT STATUS OF THE CIEMAT CONTRIBUTION TO CTF

PRESENT STATUS OF THE CIEMAT CONTRIBUTION TO CTF 3 Luis García-Tabarés, on behalf of the Accelerators Group at CIEMAT (luis. garcia@cedex. es) CTF 3 MEETING AT CERN 17/July/2008 1

ONGOING CONTRIBUTIONS * MOVERS FOR THE TBL QUADS * STRIPLINE KICKER * TAIL CLIPPER KICKER * PETS CTF 3 MEETING AT CERN 17/July/2008 2

MOVERS STATUS • A first prototype built at CIEMAT was delivered to CERN and tested • End switches were too weak and replaced with stiffer ones. • A base structure was also required by CERN • With these modifications two new units were ordered to industry • At present two companies are manufacturing these new movers (Aciturri and Ramen) • These two movers should be finished in one month (at least the first one) CTF 3 MEETING AT CERN 17/July/2008 3

CTF 3 KICKER STATUS • Kicker already installed at CTF 3 Combiner Ring. • No problems found although it still has not extracted particles. CTF 3 MEETING AT CERN 17/July/2008 4

CTF 3 KICKER STATUS • Design is already finished. • Practically all the materials & components have been acquired. • Electrodes have been manufactured • Test devices have been received or will be soon at CIEMAT (Including the pulsed power supply). • Still waiting for the reception of some more CERAMASEAL feedthroughs. • Delivery will depend on the reception of the feedthroughs and the ability to achieve 10 -8 mbar CTF 3 MEETING AT CERN 17/July/2008 5

PETS STATUS (1/2) – SINGLE BAR • The first 800 mm long bar has been successfully measured with the RF test bench • There is a 89º phase shift per cell corresponding to a detuning of 68 MHz and 13% power losses. Most of these losses are associated to geometrical errors and poor electrical contact of the test bench and should be much smaller in the real PETS CTF 3 MEETING AT CERN 17/July/2008 6

PETS STATUS (1/2) – FULL ASSEMBLY • A test of the fully assembled 8 bars is foreseen in the next two months. • The design of the power extractor is finished. Different brazing tests have been performed with bad results • The complete design of the PETS is finished. • Fabrication of the 8 bars will start soon as well as the manufacturing of the outer shell (both ordered) • Fabrication of the refrigeration system will be launched when a successful brazing procedure will be defined CTF 3 MEETING AT CERN 17/July/2008 7
