Timing Resolution and Detection Efficiency of the St. George Detector System

ORAL

Abstract

The St. George recoil mass separator at the University of Notre Dame will be used to study $(\alpha,\gamma)$ reactions of astrophysical interest. A detection system was developed for the St. George recoil mass separator, in collaboration with Indiana University South Bend, that will utilize energy and time-of-flight to separate reaction products from residual unreacted beam particles. The detection system utilizes uses two microchannel plate (MCP) detectors, which register timing measurements, and a silicon strip detector is used to measure the ion’s kinetic energy. The performance of the detection system will be presented.
