The effect of reflection is studied experimentally and theoretically on a high-power 110 GHz gyrotron operating in the TE(22,6) mode in 3 μs pulses at 96 kV, 40 A. The experimental setup allows variation of the reflected power from 0 to 33 % over a

A set of three apparatus enabling RF exposure of aerosolized pathogens at four chosen frequencies (2.8 GHz, 4.0 GHz, 5.6 GHz, and 7.5 GHz) has been designed, simulated, fabricated, and tested. Each apparatus was intended to operate at high power with

We report the recent measurement of high gradient and rf breakdown rates (BDRs) in a millimeter-wave accelerating cavity powered by a megawatt gyrotron. The cavity is powered by 10 nanoseconds rf pulses, chopped from 3 microsecond gyrotron pulses usi

The effect of reflection is studied experimentally on a 110 GHz, 1.2 MW short-pulse gyrotron. The experimental setup allows variation of the reflection from 0 to 35% over a range of gyrotron operating conditions. For high-efficiency operating points,

A reduced parameter model of fast laser-driven semiconductor switches of THz and mm-waves has been developed. The model predicts peak reflectivity and minimum transmissivity of switches, showing good agreement with experimental data, while requiring

An apparatus for measuring the W-band (75–110 GHz) complex permittivity of dielectrics at 1000 °C was developed. This apparatus allows for measurements at approximately twice the temperature of previously published high temperature free-space meas

We report initial high-gradient testing results of a 110 GHz single-cell standing wave accelerating cavity powered by a 1 MW gyrotron. The cavity is fed with 10 ns, 100s of kilowatt pulses, and achieved a field gradient up to 225 MV/m. We also report

A laser-driven semiconductor switch (LDSS) employing silicon (Si) and gallium arsenide (GaAs) wafers has been used to produce nanosecond-scale pulses from a 3 μs, 110 GHz gyrotron at the megawatt power level. Photoconductivity was induced in the waf
