We report experimental results of the operation of two ferroelectric cathodes of relatively large size. The first cathode had a diameter of 10.2 cm and was built in the Pierce cathode geometry by Integrated Applied Physics (IAP). It achieved emission

A two-component saturable gas absorber composed of formic acid and SF(6) in separate cells has been successfully used as an isolator in a TEA-CO(2)-amplifier chain for amplifying several 9-microm-band transitions. This isolator suppressed all amplifi

A single-stage depressed collector has been installed on a 1.5 MW, 110 GHz gyrotron and tested in 3 microsecond pulse operation at 96 kV and 40 A. The overall efficiency with the depressed collector was 50 % at 1.5 MW of output power with a voltage d

Stable operation in a single mode is an important goal of high-power gyrotrons. Both multimoding and switching into unwanted modes can lead to lower efficiency and undesirable heating of components not designed to accommodate parasitic modes. We have

The design and operation of a 100 kW, 140 GHz pulsed gyrotron are reported. To our knowledge, this is the highest frequency at which high gyrotron output power (>-100 kW) has been achieved. Results are presented for gyrotron operation in the range of
