SELF-MAGNETIC-FIELD-LIMITING CURRENT OF INTENSE RELATIVISTIC ELECTRON BEAM UNDER EXTERNALLY APPLIED MAGNETIC FIELD

The self-magnetic-field-limiting current of intense relat ivistic electron beam (IREB) without an externally applied magnetic field is reported and briefly commented in this paper. By using dynamic balance method the self-magnetic-field-limiting current of IREB under externally applied magnetic field is derived, showing that in this case it will increase. This result is obtained for the first time, so far as we know, and will be further tested by experiment.
