1. TBL, Status, Plans, Experiments
Status of components
Installations Plans for shutdown 2008/2009
Experiments in 2009
Outlook
CTF3 collaboration meeting, Steffen Döbert

2. 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

3. Tank integration

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

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

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

7. TBL integration into CLEX

8. TBL diagnostic section

9. TBL beam line installation ongoing
Beam line girders in place

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

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

12. What about CDR in 2010 ?
Unlikely to install more than 8 PETS until mid 2010
Can we define a feasibility result using 8 PETS
8 PETS only
E0 = 130 MeV
I=28 A
Eff = 33 % (was 65% for 16)
1.2 GW of rf power
E0 = 100 MeV
Eff = 42 %

13. ‘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

14. The current plan for TBL
Organize and launch production of at least 7 more PETS with our collaborations to be commissioned with beam in 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

15. Experiments with TBL in 2009
Evaluation of PETS tank prototype with beam and high power (Ideal: produce > 100 MW = 23A)
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

16. 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
