Abstract Emission, translation, modulation and diagnosis of short pulse intense relativistic hollow electron beams (IREBs) of a L-band relativistic klystron amplifier are described in this paper. The hollow electron beams about 500kV, 4.5kA, diameter 54.5mm, thickness 4.5mm are obtained, and 6% of beam current modulation is gotten after the electron beams get through the input cavity gap, as well as 23% of beam current modulation is gotten after the electron beams get through the idler cavity gap.
