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.
