ジャーナル フリーThe stabilization of the plasma in P.I. G. discharge have been studied in the various kinds of the magnetic field configuration, -a cusp field, a mirror field and a Heliotron type field. The frequencey spectrum and the amplitude of the anode voltage fluctuations and plasma density are measured. A stable and optimum discharge condition as a plasma source is obtained in a Heliotron type field. In such a field, the plasma noise is reduced to one fiftieth as small as that in a uniform field and the plasma density becomes much greater than in other field configurations.抄録全体を表示PDF形式でダウンロード (1647K) -

ジャーナル フリーA new type of air gop switch for crowbering is reported.
It consists of two main electrodes between which two sheets of trigger electrodes with a hole in its centre are inserted.
Trigger electrodes. are clssely spaced each other sandwitching a insulating plastic ring. When a rapid sising over volted triger pulse is applied, break-downs occur symmetrically in both gaps between main and trigger electrodes, which enables satis factoryly crowbering characteristics.抄録全体を表示PDF形式でダウンロード (284K) -

ジャーナル フリー高エネルギーアークの発光スペクトル線の形を測定し, その拡がりの半値巾からイオン温度を, その傾きからイオンの集団回転速度を。またアーク軸方向剛により, スペクトル線の波長ずれからイオンの軸方向集団速度を求めた。得られた値の最高は, アーク電極間中央で測ったイオン温度は20cV, イオンの集団回転速度はC++で7×105cm/sec, 軸方向集団速度はC++で1.5×106cm/secの程度であった。これらの量は気圧の低下 (中性粒子の減少) によって増す。電流の増加はイオンの軸方向速度を減じてイオン温度を上昇させ, 磁場の増大はイオンの集団回転速度を大拳くするとともにイオン温度を増す傾向にある。抄録全体を表示PDF形式でダウンロード (962K) -

ジャーナル フリーLight intensity of a positive column in a longi tudinal magnetic field changes with the field and becomes minimum at the critical field value when the helical oscillation appears in the positive column. As this change is very steep at the critical point even when the longi todinal electric field does not clearly show no point, the observation of the light intensity of the positive column may be useful for the detection of the critical field value.抄録全体を表示PDF形式でダウンロード (423K) -

ジャーナル フリーThis paper reports co-existence of the moving striation and the helical oscillation in the positive column in a longitudinal magnetic field. The existing regions for these oscillations are graphically obtained in relation to the magnetic field and the electric field of the column and the experimental results of the co-existence can be explained by the graph. In very short tube, thee is no critical magnetic field therefore no helical oscillation but instead the moving striation up to very large magnetic field. The striation is also affected by external conditions such as discharge current, heater current etc.抄録全体を表示PDF形式でダウンロード (675K) -

ジャーナル フリーIn the present paper are described the results of experiment on the interaction between a plasma, in particular, its electron component and a microwave in some types of magnetic field. A static magnetic field was externally produced v a pair of air core coil blocks consisting of some seperated coils, and a cylindrical cavity was set between the coil blocks. A, plasma beam was stationarily injected into the cavity on and along its axis, Microwave power was pulsively fed into it from a magnetron oscillator, too. The interaction in interest was investigated by measuring the flux and energy of soft x-rays emitted from plasma with an x-ray detector, and by analysing pulses of current diffusing across magnetic lines of force accepted by a probe. The emission of soft x-ray was observed only when the magnetic field was of mirror geometry, and was found to depend strongly upon the position of electron cyclotron resonance zone in a mirror field. Furthermore, the observation of pressure dependence of the emission showed that, if any gas was used, secondary electrons produced by fast ones in the trapping region could gain much energy from the microwave and become energetic particles, under an appropriate condition. From the decaying slope of probe current pulses was obtained the mean lifetime of trapped particles, from which some informations about the accelerating rate for trapped electrons could be got as well as from the x-ray energy. In the final part of this paper interpretations of the results mentioned above are made from the view of the single particle model.抄録全体を表示PDF形式でダウンロード (1859K)
