On a Two-Stage Double-Focusing Mass Spectroscope under Construction at Osaka University
Planning to construct a huge tandem type mass spectroscope at Osaka University was begun in 1967 (1), in order to determine atomic masses to an accuracy of nearly one order of magnitude higher than we had obtained so far. The new mass spectroscope consists of two sets of double focusing analyzers, each of which has a energy selector with cylindrical electric field and a momentum selector with uniform magnetic field. These sets are aligned in tandem with turned over S-shape.
