Masataka Hirose1986 Volume 55 Issue 6 Pages 449-460
Published: June 20, 1986
Released on J-STAGE: March 04, 2011
JOURNAL FREE ACCESSVarious kinds of inorganic and organic materials have been synthesized by plasmaassisted chemical vapor deposition (plasma CVD) technique, in which the reactive gases are decomposed in a glow discharge and the thin films can be grown on substrates at temperatures even below 300° C. This paper reviews the basic concept of plasma CVD technique, gas phase reactions in plasma, and deposition kinetics. Recent progress and future prospect in this field are also described.View full abstractDownload PDF (1206K) -
Yutaka Tuzi1986 Volume 55 Issue 6 Pages 461-475

JOURNAL FREE ACCESSHot cathode ionization gauges are widely used for the pressure measurements in high and ultrahigh vacua. This review covers the fundamental techniques for the measurement of pressures by ionization gauges. The indications of ionization gauges are proportional to the molecular density and the gauges require calibration. The gauges can be compared with an absolute gauge or they can be attached to a system in which a known standard pressure can be generated. Characteristics of diaphragm gauges, spinning rotor gauges, and ionization gauges are reviewed in conjunction with the reference transfer gauges for the standard pressures.View full abstractDownload PDF (1757K) -

Yun Shen, Shuichi Takamura, Goro Aoyama, Takayoshi Okuda1986 Volume 55 Issue 6 Pages 491-504

JOURNAL FREE ACCESSThe effect of radio frequency electric field on the initiation of plasma induced bi-polar arc was studied with a titanium rod inserted inside a toroidal plasma. The superposition of relatively low frequency field on the voltage impulse made the arc initiation voltage lower than that without RF. On the contrary the superposition of relatively high frequency field made it higher than that. The physical mechanisms for explaining these apparently opposite results were proposed. The relation between the arcing and the impurity release in high power wave heating experiments was discussed.View full abstractDownload PDF (1412K) -

JOURNAL FREE ACCESSThe effects of operational modes of the R-project fusion machine on the total tritium inventory are discussed by the use of TCODE which has been originally developed at ANL. The effects of the dwell time, the burn time, and the fractional burnup on the tritium inventory are elucidated.
Air detritiations in the R-project fusion machine building are shown graphically as a function of elapsed time after the accidental release of tritium by the use of TSOAK code developed at ANL. The effects of air flow rate on the detritiation, the formation of TH and THO, and the amount of tritiated species soaked into the building surface of the R-project fusion machine are also evaluated.View full abstractDownload PDF (921K)
