The Design of Sheet-beam Electron-gun for High–power Microwave Sources
نویسندگان
چکیده
A set of software tools based on Pierce theory and the Cutler-Hines approach for thermal velocity effects have been developed for the design of sheet-beam electron guns. The tools yield parameters for rudimentary gun geometry, which are further refined using the 2-D particle-in-cell code EGUN. Candidate designs for guns suitable for applications to high-power, high-frequency microwave sources have been obtained. The results indicate good potential for the use of sheet-beams to generate microwaves applicable to future accelerators.

Faraday cup measurement shows that the beam radius is 4.1 mm...
متن کاملDevelopment of Multiple Beam Guns for High Power RF Sources for Accelerators and Colliders
There is a need for high power RF sources for the next generation of accelerators and colliders. Sources that operate at reduced beam voltage allow solid state power supplies with significant cost reduction over conventional pulse modulators. Multiple beam RF sources provide reduced beam voltage by using a multiplicity of beamlets that traverse the RF circuit through individual beam tunnels, re...

متن کاملA Permanent-Magnet Microwave Ion Source for a Compact High-Yield Neutron Generator∗
We present recent work on the development of a microwave ion source that will be used in a high-yield compact neutron generator for active interrogation applications. The sealed tube generator will be capable of producing high neutron yields, 5 ·10 n/s for D-T and ∼ 1 ·10 n/s for DD reactions, while remaining transportable. We constructed a microwave ion source (2.45 GHz) with permanent magnets...
متن کاملSpatial–temporal Hysteresis Effects in an Intense Electron Beam
An electron gun with large compression of a thin annular beam for generation of high-power microwaves and IR radiation has been designed. Computer simulations of beam formation in the gun show some hysteresis effects: a beam with different current can exist in the same external conditions. At the upper (metastable) part of a hysteresis curve the beam current exceeds Child-Langmuir current. Expe...
