New X-band testing facility a.k.a. Xbox 2

1. New X-band testing facility a.k.a. Xbox 2 N. Catalan. Lasheras for the X-band testing areas (XTA) activity group N. Catalan Lasheras

2. What is Xbox2? N. Catalan Lasheras • A new test bench for testing RF structures at 12GHz above 100MV/m • One structure/three months testing • CPI VKX-8311A, 50MW klystron • First of this model under construction • Based in SLAC XL5 tube • Scandinova50Hz, 450kV modulator • Full time operation expected from next year. • Possible extension in 2014-15 (Xbox3) when Linac4 klystrons/waveguides are installed

3. From last collaboration meeting. (I. Syratchev) #2 50 MW klystron (XL-5, CPI) test stand will be able to deliver to the testing area up to 130 MW x 250 ns pulses at 50 Hz repetition rate. The overall power consumption is 43 kW.

4. Xbox1 in building 2013 N. Catalan Lasheras CTF2 CTF3 klystron gallery

5. Building 150. 352 MHz test stand N. Catalan Lasheras

6. Proposed layout for Xbox2 in buidling 150 N. Catalan Lasheras Dmitry Gudkov. RF-PM. See also EDMS 1238874

7. Proposed layout for Xbox2 in buidling 150 Test bunker Dmitry Gudkov. RF-PM • Bunker to be reused as such with small modifications • Chicane modified to minimize waveguide length • Radiation measurements done in Xbox1 indicate shielding shall be reinforced on axis • Modulator uses existing water/electricity distribution • Top-left area used by the EBIS source tests at least until the end of 2013 (TBC) Vacuum/TWT Modulator Working area N. Catalan Lasheras LLRF

10. Bunker area Dmitry Gudkov. RF-PM N. Catalan Lasheras • Vacuum sectors for fast turn around • Loads an waveguide network baked-out • Bake-out of the DUT after installation • Adjustable length for DUT • Single and double structures • Additional capacity for extra diagnostics

11. Pulse compressor • First piece of Xbox2!! • Compact SLED type pulse compressor. • RF measurements and final tuning next week!! • Four more units required • Review of the concept, fabrication, mechanic support etc., by the end of February.

12. RF components procurement ‘’Simple” -60 dB directional coupler. Range of components developed for X band Design and prototyping ready end 2012 First orders expected by the end of May New x-band flanges for Xbox3

13. LLRF N. Catalan Lasheras • No beam. No synchronizing timing required. • Signal generation, diagnostics and control can be done within a NT PXI rack • Frequency multiplication and down conversion • Successful tests in the lab • Temperature regulated rack (BI)

14. Status of the Xbox N. Catalan Lasheras • Preparation of the site • Final layout of the test stand. January 2013. • Cleaning-up the area. • Safety file preparation. RP shielding estimations done. • Shielding reinforcement . • Water system modification. • Electricity modification. • Cabling, Ethernet, compressed air. • Installation • Modulator procurement. End of March 2013. • Klystron delivery. Delayed by 4 months!! • RF network and components. End of May 2013. • Vacuum network, pumps and valves. LLRF and controls. • Commissioning • Modulator/klystron unit. • Conditioning of RF network surely 2014. • Constrains • LS1 resources availability. • Water cut due to LS1 from mid-may until beginning 2014.

15. Planning N. Catalan Lasheras

16. Schedule adjusted N. Catalan Lasheras Yesterday Today

17. Future:Xbox3. Cluster of small power units Xbox2 Xbox 3 • Market survey for klystron-modulator units out • Call for tender in the next weeks • Components procurement under way • Waiting for new flanges • Plan to start installation in2015

18. In summary N. Catalan Lasheras • New test facility preparation on-going • Site identified • Klystron and modulator under construction • RF components under procurement • Site preparation starting • Still learning from Xbox1 and dog-leg experiences • Preparing the way for Xbox3 • X-band test capacity multiplied by 3!!
