高性能水素離脱測定装置 A High-Performance System for Hyrogen Evolution Measurement コウセイノウ スイソリダツ ソクテイソウチ 芦﨑, 馨介 アシザキ, ケイスケ 西川, 泰央 ニシカワ, ヤスオ 青木, 彪 アオキ, タケシ ASHIZAKI, Keisuke NISHIKAWA, Yasuo AOKI, Takeshi The paper concerns a hydrogen evolution measuring system which adopts a minimized sample tube, VCR metal-sealing gaskets in a whole sampling system and personal-computerized temperature control and data processing. The quartz sample tube of 5mm diam. and 85mm length is welded to a Pylex glass of glass-metal transition tube having a VCR joint at a metal end. The heating rate can be varied from 0.6℃/min to 60℃/min and kept constant within ±10% for the rate more than 5℃/min except for a start of H-evolution, using ramp-function generated by PC for a set-point and PID control algorithm. The minimum weight, of the sample i. e. a-Ge : H with hydrogen content of 10 at. % is estimated to be 3μg from the back-ground pressure of 1.4mTorr at 800℃. Its consistency with the experimental observation is discussed reffering to molecular hydrogens trapped in the film. A preliminary observation of H-evolution spectra of a-Ge : H film produced by ECR plasma CVD also is described. 14 KJ00001512054 論文 Article 1996 jpn departmental bulletin paper https://kougei.repo.nii.ac.jp/records/279 AN00159741 03876055 東京工芸大学工学部紀要 The Academic Reports, the Faculty of Engineering, Tokyo Polytechnic University 19 1 65 71 https://kougei.repo.nii.ac.jp/record/279/files/KJ00001512054.pdf application/pdf 486.7 kB 2017-04-21
