Design of a High - Power , High - Gain , Frequency - Doubling Four - Cavity Gyroklystron
In this paper we consider the design of a four-cavity microwave circuit for a high-gain K-band gyroklystron. The goal is to use this device to test a high gradient linear accelerator structure. The frequency doubling circular gyroklystron uses a beam voltage of 500 kV, beam current of 200 A in the circular TE011 mode and provides an output in the TE021 mode. We study the behavior of the four-ca...
متن کاملHigh-power operation of a K-band second-harmonic gyroklystron.
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 ...
متن کاملDevelopment and Testing of a High-Average Power, 94-GHz Gyroklystron
The development of a 10-kW average power, 94-GHz gyroklystron amplifier is described. This average power was obtained with 11% radio frequency (RF) duty factor and 92-kW peak power in the TE01 circular cavity mode. The instantaneous bandwidth was 420 MHz, and the efficiency was 33.5%. Low-duty-factor testing also yielded a peak power of as much as 115 kW with 600-MHz instantaneous bandwidth. Th...
متن کاملEfficient 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...
متن کاملEfficient 2.45 GHz Rectenna Design with High Harmonic Rejection for Wireless Power Transmission
The purpose of this work is to propose an efficient microstrip rectenna operating on ISM band with high harmonic rejection. The receiving antenna with proximity coupled feeding line implemented in a multilayer substrate. The rectenna with integrated circular sector antenna can eliminate the need for an low pass filter (LPF) placed between the antenna and the diode as well as produce higher outp...
