• We present an analysis of the characteristics of the noise from a magnetized high-current electron beam at a nanosecond-long interval since the explosive electron emission onset on the graphite cathode by applying accelerating pulses with an amplitude of about −300 kV and a varying subnanosecond rise time. The registration bandwidth of electromagnetic noise and the beam current modulation was as high as 59 GHz. A leading wideband electromagnetic signal linked with a short beam current front was recorded. Subsequent noise, including that with discriminated spectral maxima, can be qualified as spontaneous cyclotron radiation of moderately relativistic electrons rotating in a longitudinal magnetic field.
