海野聡平; 金高 崇; 岩瀬千克; 柳平丈志; 鶴田浩一, Gate driving circuit by magnetic chain mechanism for series operation of field effect transistors was developed. Serial connection of field effect transistors was employed to generate pulses of high voltage and a short rise time. The whole circuit is divided into many cells containing a transistor and an associated gate driving circuit, and the cells are magnetically triggered successively by applying an external trigger pulse on the first cell. The switching characteristics of the cells were investigated at voltages up to 5 kV, and the rise time of the output voltage was 22 ns at 500Ωload., The Institute of Electrical Engineers of Japan

電気学会論文誌Ａ, 01 Jul. 2006, [Reviewed] - 小電流ＤＣ真空アークの挙動と維持特性に及ぼす磁界の効果
柳 健吾; 柴田 智; 柳平丈志; 鶴田浩一, Effect of magnetic field on sustainment and dynamics of low current DC vacuum arcs, less than 20 A, were examined. Without magnetic field, the cathode spot moves at random on the cathode surface and the arc voltage is constant for increasing gap length up to 30 mm. In the axial magnetic field, the arc plasma was constricted and the arc voltage rose with increasing gap length. When a magnet was arranged behind the cathode, the cathode spot rotated in the opposite direction of the Lorentz force (J x B) on the edge of the cathode. On the other hand, when a magnet was arranged behind the anode, the arc column was constricted on the electrode axis and the lifetime of the arcs was extremely extended., The Institute of Electrical Engineers of Japan

真部泰幸; 柳平丈志; 鶴田浩一, Time of flight method in the form of ion acceleration by a negative square pulse is investigated for lead ion plasma generated from a short burning time impulse vacuum arc. In the method, lead ions existing between the grid with earth potential and the accelerating grid which is connected to the ion accelerating tube are accelerated into the tube by applying a negative square pulse voltage to the accelerating grid. The ions fly toward the ion collector with a constant velocity dependent on the charge state. The effect of an axial magnetic field in the accelerating tube on the loss of the flying ions and on the obtained rate of the densities of Pb+1 and Pb+2 ions in the arc plasma is discussed. The relation between the amount of the accelerated ions and the accelerating voltage is also investigated from the viewpoint of time dependent propagation of the ion sheath, which is formed in front of the accelerating grid., The Institute of Electrical Engineers of Japan
