摘要：

We have recently proposed to combine the advantages of a pseudospark-sourced sheet electron beam (PS-SEB) with a planar slow wave structure to generate high power terahertz radiation. To verify this idea, experimental investigation of an extended interaction oscillator based on the PS-SEB has been conducted and presented. A PS-SEB of approximately 1.0mm x 0.17mm in size with 21.5A peak current (1.26 x 10(4) A/cm(2) beam current density) and 34.5 kV peak voltage was measured after propagating a distance of 10-mm without the need of an external focusing magnetic field. A radiation pulse of similar to 35 ns in duration and an output power of over 10W at a frequency of similar to 0.2 THz were measured. Published by AIP Publishing.
