A gyrotron and a waveguide transmission line, which were developed for electron cyclotron heating and current drive in JT-60SA, have been tested to evaluated its high-power, long-pulse and multi-frequency capabilities. High-power oscillations up to 1.8 MW at 110 GHz and 1.3 MW at 138 GHz have been obtained so far. The spatial distribution of the temperature increase of the waveguide transmission line...
Long pulse operation of a dual frequency gyrotron for JT-60SA, which can oscillate both 110 GHz and 138 GHz waves, was started. Oscillations at ∼ 0.4 MW for 2 s (both frequencies) and 0.7 MW for 1 s (110 GHz) were obtained, so far. Temperature increase in the cavity, the output window and some components, which absorb stray radiation in the gyrotron, were measured and cavity loss power and the dielectric...
This paper introduces a novel image recognition method based on the neural oscillator network. In the present method, the dynamics of neurons is determined from neural coupling strengths relevant to the similarities in pixel levels, which have been used in the conventional image segmentation, as well as geometrical local features obtained from the Gabor filtering. Then the image regions under resultant...
