Paper Abstract

The outstanding results of the EGRET experiment on CGRO have stimulated the search for a next generation of high-energy gamma-ray telescope. We discuss here the use of scintillating optical fibers for the development of a new type of gamma-ray telescope operating in the energy range 10 MeV and above. An all-sky high-energy monitor with ten times EGRET's sensitivity and superior detector characteristics is described. The detector is composed of layers of lead and plastic scintillating fibers that perform both the shower direction and energy measurement. We present here simulations of a system with ten radiation lengths of lead in it and show how the system achieves good directional accuracy and energy resolution. We also discuss the characteristics of a baseline technology demonstration module designed to verify the performance of the SIFTER system components.
