چکیده

Amplification studies of a two-cavity second-harmonic gyroklystron are reported. A magnetron injection gun produces a 440 kV, 200-24S A, 1 ps beam with an average perpendicular-to-parallel velocity ratio slightly less than 1. The TED» input cavity is driven near 9.88 6Hz and the TE02& output cavity resonates near 19.76 6Hz. Peak powers exceeding 21 MW are achieved with an e%ciency near 21% and a large signal gain above 2S dB. This performance represents the current state of the art for gyroklystrons in terms of the peak power normalized to the output wavelength squared.

Estimation of the Electronic Efficiency of a Gyroklystron Amplifier

In the present paper, a generalized self-consistent single mode linear analysis of gyroklystron has been presented. The analysis has been used to estimate and optimize the electronic efficiency of the gyroklystron device. The efficiency contours, necessary for the preliminary design of a gyroklystron, have been drawn by solving the coupled equations using Runga-Kutta method for the various devi...

Modeling of Gyroklystrons with MAGY

The self-consistent time-dependent code MAGY is presently being used for designing and modeling gyrodevices. In this paper, the code’s self-consistent capability is used to investigate three different issues relating to the operation of gyroklystron amplifiers. These are the effect of window reflection on the properties of the output waves, higher order mode excitation in nonlinear output taper...

Efficient operation of a high-power X-band gyroklystron.

Experimental studies of amplification in a two-cavity X-band gyroklystron are reported. The system utilizes a thermionic magnetron injection gun at voltages up to 440 kV and currents up to 190 A in 1-ps pulses. Optimum performance is achieved by tapering the magnetic-field profile. Peak powers of 20 MW in the TED] mode at 9.87 6Hz are measured with calibrated crystals and with methanol calorime...
