The sheet-beam klystron holds great promise for providing
high RF power for modern linear colliders.
However, sheet beam generation is not readily amenable to computer
simulation; therefore, experimental validation of the design is sorely
needed. This project will develop a demountable sheet beam analyzer with a fluorescent
screen for direct observation of the electron beam cross section. In Phase I, an analyzer with a fluorescent
screen was designed, fabricated, and tested with a new kind of sheet-beam gun,
which morphs a round beam into an elliptical beam. Two versions of the analyzer were fabricated
and succussfully tested: one version was
used to test the fluorescent screen, the second to provide direct viewing of the
elliptical beam cross section. In Phase
II, two 500-kV beam analyzers will be designed, fabricated, and tested at high
voltage at the Standford Linear Accelerator Center.
Commercial Applications and Other Benefits as described by the awardee: The demountable beam analyzer should provide significant value for the design of future sheet-beam klystrons. The technology also offers the potential for providing RF power from light-weight, affordable generators for use with portable X-ray scanners of thousands of shipping containers.
