Research on Multi-Pulsed Intensive Electron Beam Source

  •  Institute of Fluid Physics, China Academy of Engineering Physics, Mianyang 621900, China

  • This paper is involved in multi-pulsed emission characteristics of some cathodes while generating intensive relativistic electron beams. Research results indicate that the velvet, the carbon fiber and the dispenser cathode all have the ability to generate a few kilo-ampere multi-pulsed beams with brightness better than 3×107A/(m.rad)2. And some new cathodes such as carbon nano-tubes and nano-diamond film also can generate a few kilo-ampere multi-pulsed electron beams. Because of the cold field emission, the beams generated by the carbon nano-tubes and the nano-diamond film are expected to be higher brightness. Some experimental results of above cathodes are present and some suggestion for farther work is also proposed.

Abstract: This paper is involved in multi-pulsed emission characteristics of some cathodes while generating intensive relativistic electron beams. Research results indicate that the velvet, the carbon fiber and the dispenser cathode all have the ability to generate a few kilo-ampere multi-pulsed beams with brightness better than 3×107A/(m.rad)2. And some new cathodes such as carbon nano-tubes and nano-diamond film also can generate a few kilo-ampere multi-pulsed electron beams. Because of the cold field emission, the beams generated by the carbon nano-tubes and the nano-diamond film are expected to be higher brightness. Some experimental results of above cathodes are present and some suggestion for farther work is also proposed.
