Introduction to WP12: Normal Conducting High-Gradient
Walter Wuensch, CERNEUCARD2 WP12, CEA SACLAY 16 April 2014
Where are we with X-band and high-gradient?
• Accelerating gradients above 100 MV/m now routinely and reproducibly achieved.
• Industry is now supplying X-band klystrons.• Micron-precision technology spreading rapidly in
industry.

Accelerating structure performance summary
We are able to now predict very accurately the accelerating gradient a particular design will have.

Where are we going with X-band and high-gradients?
• Deepen the technological base • New X-band klystron design from SACLAY• Instrumentation and electronics from PSI• Test-stand optimization from Uppsala• Alternative design of HOM supression from Manchester
• Broaden the use in accelerators• Crab cavity/deflector development from Lancaster and STFC
• New applications• Medical linacs• XFELs
