Status of the prototype components PETS tank: under fabrication at CIEMAT (see Fernando’s talk) BPM’s: 2 prototypes finished, one installed and tested with beam Series: under fabrication (see Angeles talk) Quads: Prototypes finished and accepted Series delivery end February Quad-Movers: Prototype installed and tested, Series under fabrication (see F. Toral) High power rf: directional couplers, loads prototypes under fabrication, Series: CEA white paper contribution for 8 sets Low Level rf: channels for prototypes testing available Other Beam diagnostics: defined and under fabrication

Tank integration

Quadrupole production at BINP Acceptance test of first prototype done in December 2008 successfully (see Antony’s talk)

BPS under beam test Tested with beam successfully First beam with losses, Ringing problem has been investigated and solved by the experts in a nice collaborative effort

RF components prototypes, high power load at factory Water load with disk window, compact and inexpensive More risk, therefore back up of ‘standard’ components

TBL integration into CLEX

TBL diagnostic section

TBL beam line installation ongoing Beam line girders in place

Installation-Schedule Limited by component arrival, we will have one PETS tank and 3 movers

Pets production scenario Two independent production lines assumed (CIEMAT, CERN)

What about CDR in 2010 ? Unlikely to install more than 8 PETS until mid 2010 Can we define a feasibility result using 8 PETS only E 0 = 130 Me. V I=28 A Eff = 33 % (was 65% for 16) 1. 2 GW of rf power E 0 = 100 Me. V I=28 A Eff = 42 %

‘Advantages’ of 8 PETS for CDR and 8 PETS later Lower risk, since PETS are not fully verified Fabricate the next generation PETS for the second half lower cost improved engineering improved designs improved damping new on/off better adapted for two beam acceleration prototypes for new facility ? Easier experimentation to start with

The current plan for TBL Organize and launch production of at least 7 more PETS with our collaborations to be commissioned with beam in 2010. Approach: parallel fabrication at CIEMAT and CERN using multiples vendors CDR demonstration measurement milestones at the end of 2010 Assuming continuous production with two institutes in parallel TBL could be completed in 2011 profiting from first series experience Second batch has to be launched early 2010 Full demonstration of drive beam decelerator end of 2011

Experiments with TBL in 2009 Evaluation of PETS tank prototype with beam and high power (Ideal: produce > 100 MW = 23 A) Produce > 20 A drive beam Resolution measurement of BPS (5 microns specified) Beam based quad alignment with mover Commission beam line and diagnostics Transport beam with 2 or 3 PETS installed Measure beam properties

Conclusions TBL is happening now Delays a bit everywhere, components, planning, testing, fabrication, but still reasonable given the available resources and complexity Beam line installation planned for winter shutdown, short stop in fall 2009 to install more PETS if possible Critical to test PETS tank prototype, pacing item for future decisions ! Testing rf components might become an issue Overall TBL goal with respect to CDR in 2010 has been reviewed
