Zusammenfassung:The experimental study of a pseudospark discharge sourced electron beam with post acceleration (PA) is presented. The PA circuit was used to drive a W-band extended interaction oscillator. The experiments showed a significant increase in the output power, with 200 W at 94 GHz measuring corresponding to a 5 times increase in the output power as compared to when post acceleration is not used. The microwave device developed has the advantage of not requiring an external magnetic field making it a low cost, compact, and portable sub-terahertz radiation source.
