ABSTRACT
A compact E parallel B (E||B) type end-loss ion mass-resolving energy analyzer was fabricated and tested. In the analyzer, a small-angle deflection magnet and a preaccelerator/decelerator of end-loss ions are adopted in order to reduce the size and to expand an energy range with a sufficient energy resolution. Orbit calculations in the E||B fields including the influence of fringe fields were made by a Monte Carlo code in which the effects of finite radius and angle of the incident ions are taken into consideration. Preliminary measurements on the GAMMA 10 tandem mirror were successfully performed and it was confirmed that the analyzer has capabilities for the spectrometer of end-loss ions.
