Present Status of the Two Stage Double Focusing Mass Spectroscope at Osaka University
Autor: Hiromitsu Nakabushi, Itsuo Katakuse, Koreichi Ogata
Publikováno v: Journal of the Mass Spectrometry Society of Japan. 23:247-269
With the intention to determine the atomic masses in the accuracy up to the order of magnitude of 10-9, in 1967 we were planning to construct a new large tandem type mass spectroscope. The machine consists of two sets of first order double focusing m

Rare gas studies of sixteen stony meteorites from Antarctica
Autor: Keisuke, Nagao, Koreichi, Ogata, Nobuo, Takaoka, Kazuo, Saito
Publikováno v: Memoirs of National Institute of Polar Research. Special issue. 30:349-361
The concentrations of rare gases and isotopic compositions of He, Ne and Ar were determined for fourteen chondrites and two achondrites from Antarctica. The Xe isotopic ratios were also determined for seven meteorites. Cosmic-ray exposure and gas ret

High Resolution Mass Spectrometer for Analysis of Organic Compounds
Autor: Yasuo Nakajima, Hitoshi Tsuyama, Takeshi Koike, Koreichi Ogata, Tamotsu Noda
Publikováno v: Journal of the Mass Spectrometry Society of Japan. 13:1-10
A double focusing mass spectrometer was constructed for the organic structural analysis. The electrostatic sector was designed as an attachment of the Hitachi RMU-6D mass spectrometer system. The dimensions for the ion trajectory were chosen as follo

A100-kV DC Stabilized Power Supply for Ion Acceleration of Two-Stage Double-Focusing Mass Spectroscope
Autor: Hiromitsu Nakabushi, Tadatetsu Hattori, Koreichi Ogata
Publikováno v: Journal of the Mass Spectrometry Society of Japan. 22:1-14
For ion acceleration of the two-stage double-focusing mass spectroscope, which adjustment works are going on at Osaka University, a 100-kV dc stabilized power supply has been designed and constructed. The specifications given the supply are as follow

Residual Gases in Metal Vacuum System
Autor: Atsushi Fujinaga, Jun Okano, Koreichi Ogata, Masami Michijima
Publikováno v: SHINKU. 5:22-27
Mass spectrometrical investigation of residual gases in a stainless steel enveloped mass spectrometer, evacuated with a titaniumgetter ion pump, was carried out. Partial pressure of nitrogen of 10-13 mmHg could be measured by means of a secondary ele
