"Backward-Wave Suppression Analysis, and Design and Fabrication of a Prototype Millimeter-Wave Ring-Bar Slow-Wave Structure"


A challenge for high-power millimeter-wave (mmw) traveling-wave tube (TWT) amplifiers is to realize high-power operation without incurring oscillation from backward-wave (BW) interaction. Conventional wisdom purports that contrawound (including ring bar) helix TWTs are superior to monofilar helix TWTs for stability against BW oscillations due to a zero or at least greatly suppressed BW interaction impedance (KBW) compared with the forward-wave (FW) interaction impedance (KFW). more...

"Stabilized Operation of a Microwave Compressor Driven by Relativistic S-Band Magnetron"


The stabilized operation of a microwave compressor based on a travelling wave resonator, producing at its output microwave pulses with a power of (1.15~pm ~0.05) GW and duration of (12 pm 2) ns, is described. The compressor is pumped by a relativistic S-band magnetron generating microwave pulses with a power up to 250 MW and duration of (sim 100) ns. more...

"A High Vacuum, High Electric Field Pulsed Power Interface Based on a Ceramic Insulator"



Improving the flashover voltage in a vacuum interface between a pulsed-power system and a vacuum region has been a goal for many years. The interface problem is difficult because of the electrical, mechanical, and vacuum issues that must be satisfied simultaneously. In this paper, according to the theories of vacuum flashover and the design rules for high electric field insulators, a ceramic insulated vacuum interface is presented. more...
