The paper studies the influence of semiconductor structure on microwave oscillation phase stabilization in a nanosecond Gunn oscillator during the modulating voltage pulse rise time. The phase deviation depending on the pulse amplitude and rise time was determined by numerical simulation. The standard deviation of the microwave oscillation phase delay about a fixed level within the modulating pulse...
We have developed a relativistic Ka-band backward wave oscillator (BWO) capable of generating stable 250-ps pulses of peak power up to 300 MW. The BWO operates in a 1-s burst mode at a PRF of 1–3.5 kHz.
A high current e-beam accelerator for pumping of the 200 liter eximer laser is developed providing electron energy of 550 keV, diode current of 320 kA, e-beam current of 250 kA. The high voltage part of the accelerator consists of two linear transformers with the stored energy of 98 kJ. In order to reduce the influence of the self magnetic field on e-beam formation the vacuum diode is divided into...
