Klystron Milestone Achieved

By Davide Castelvecchi

On June 4, the Klystron Department celebrated the full-spec operational success of the XP-3 Klystron, a milestone in the warm-technology development for the Next Linear Collider. Project leader Daryl Sprehn was at the picnic with his main collaborators Erik Jongewaard and Andy Haase.

“The development of the XP-3 tube has been an ongoing, 5-year effort, involving virtually everyone in the department,” Sprehn said. “The department is very busy building tubes for the Main Linac and the B Factory as well as rf components, accelerating structures and other special projects. It is amazing that time is still found to produce the world’s most powerful klystrons at the cutting edge of technology.”

Running at four times the frequency of SLAC’s linac, the XP-3 is the world’s first stable 75-megawatt periodic permanent magnet klystron.

Its predecessor, the XP-1, was constructed and completed testing back in 1999 and was limited to low levels of average power not suitable for the NLC parameters.
