Position sensitivty with the St. George time of flight vs energy detection system

At the University of Notre Dame the St. George recoil mass separator will be used to study $(\alpha,\gamma)$ reactions of astrophysical interest. The particle identification system developed for the St. George recoil mass separator at the University of Notre Dame, in collaboration with Indiana University South Bend, utilizes time-of-flight and energy to separate reaction products from residual unreacted beam particles. The detection system uses two microchannel plate (MCP) detectors for time-of-flight, and a silicon strip detector to measure the particles kinetic energy. A position sensitive anode was designed in collaboration with Indiana University Bloomington to enhance particle identification (PID). The performance of the PID system will be presented.
