Magnetron priming by multiple cathodes
DOI:10.1063/1.2031928.png)
Abstract
En 中文
A relativistic magnetron priming technique using multiple cathodes is simulated with a three-dimensional, fully electromagnetic, particle-in-cell code. This technique is based on electron emission from N/2 individual cathodes in an N-cavity magnetron to prime the pi mode. In the case of the six-cavity relativistic magnetron, pi-mode start-oscillation times are reduced up to a factor of 4, and mode competition is suppressed. Most significantly, the highest microwave field power is observed by utilizing three cathodes compared to other recently explored priming techniques. (c) 2005 American Institute of Physics.
