Abstract

A double-arm spectrometer using a micro-channel plate and two large two-dimensional PIN diode arrays was constructed to perform double-energy double-velocity (2E, 2ν) fission experiments with additional folding angle information. An event-by-event data analysis method is described. A method to determine simultaneously the pulse height defect and the mass resolution of the spectrometer is developed. The spectrometer was used in the study of 235U(nth, f), 252Cf(sf) and antiproton induced fission reactions. Mass, velocity and energy distributions of 235U(nth, f) and 252Cf(sf) are presented. The advantages of such a spectrometer are discussed.
