Fission fragment mass reconstruction from Si surface barrier detector measurement

Abstract

A method for plasma delay and pulse-height defect corrections for Si surface barrier detectors (SBD) is presented. Based on known empirical formulae, simple approximations involving the measured time of flight (TOF) and energy of the ions were found and a mass reconstruction procedure was developed. The procedure was applied for obtaining the fission fragment mass and angular distributions from the 64Ni+ 197Au reaction at 418 and 383 MeV incident energy using an array of eight SBDs.
