For the ultra high-power, X-band klystrons required
by the Next Linear Collider (NLC) and future high energy particle accelerators
and colliders, the Department of Energy, in 1988, established the goal of
achieving a radio frequency (RF) peak output power of 100 MW at a pulse width of
1 s.
This goal has not yet been realized. In
1995, the goal was relaxed to a peak power of 75 MW and a pulse length of 3 s. This
goal has not yet been realized. This
project will complete the development of a 50 MW, 11.424 GHz, high efficiency,
multiple beam klystron (MBK). The
klystron will use an eight-beam electron gun that is currently under
construction in another SBIR Phase II project. Phase
I designed a seven-cavity, multiple beam klystron compatible with the electron
gun currently being constructed. In
Phase II, the electrical design will be optimized, based on beam analyzer
measurements of the electron gun. Following
completion of the electrical design, a thermo-mechanical analysis will be
performed on all critical components. Detailed
drawings will be generated, and the tube will be fabricated, baked, and tested
to full power.
Commercial Applications and Other
Benefits
as described by awardee: It is estimated that
between 2000 and 4000 of these klystrons will be required for NLC. The
device also would have significant implications for other applications,
including RADAR, electronic countermeasures, and communications.
