Observation of Simultaneous Oscillation of Multiple Modes in a CW 300 GHz Gyrotron
نویسندگان
چکیده
Multi mode oscillation was observed in a 300 GHz fully CW gyrotron. It has been developed and installed in Research Center for Development of Far-Infrared Region, University of Fukui as a power source of a submillimeter wave material processing system. This gyrotron delivers 1.75 kW / CW at maximum. The radiation pattern is a Gaussian beam when the magnetic field strength Bc at the cavity is properly adjusted. However, within a range of Bc, simultaneous oscillation of competing modes is observed, which manifests in radiation of the output power into multiple directions.

Influence of reflections on the operation of the 2 MW, CW 170 GHz coaxial cavity gyrotron for ITER
The influence of reflections on the operation of the 2 MW, CW 170 GHz coaxial cavity gyrotron oscillating in the TE34,19 mode is studied. In particular, frequency-independent power reflections, e.g. from plasma or some elements of the transmission line, larger than 1% and occurring in a poor phase may lead to oscillation breakdown and should be avoided. Frequency-dependent reflections from a sp...
متن کاملNew trends in gyrotron development
Gyro-devices provide the highest CW or average power of microwaves in centimeter, millimeter and submillimeter wavelength ranges and therefore they are very attractive as microwave sources for many of applications such as plasma fusion, radiolocation, ion sources, telecommunication, technology, spectroscopy and some other. In last years an essential progress in the device development was demons...
متن کاملFirst experiments with gasdynamic ion source in CW mode.
A new type of ECR ion source-a gasdynamic ECR ion source-has been recently developed at the Institute of Applied Physics. The main advantages of such device are extremely high ion beam current with a current density up to 600-700 emA/cm(2) in combination with low emittance, i.e., normalized RMS emittance below 0.1 π mm mrad. Previous investigations were carried out in pulsed operation with 37.5...
متن کاملHigh efficiency quasi-optical mode converters for overmoded gyrotrons
This thesis reports on the design and experimental verification of two novel high efficiency quasi-optical mode converters for gyrotron oscillators. Gyrotrons produce high order TEm,p modes (m, p > > 1) at high frequencies (100-300 GHz). These modes must be converted to low order linearly polarized modes for transmission in corrugated waveguides or open mirror transmission lines. Because tradit...
متن کاملDetection of power oscillation and simultaneous faults using Clark transform
Distance relays are widely used to protect transmission lines. Sometimes, in these lines due to the occurrence of the oscillation of the power, the impedance calculated in the distance relay enters into its functional zones and leads to the cutting off of the lines. This issue can cause global power outages. Accordingly, in this paper, a Clark-based method for detecting the oscillation of power...
