Possible uses of gamma-rays at future intense positron sources

Abstract

The baseline design of the ILC (International Linear Collider) positron source requires the production of an intense flux of gamma rays. In this paper we present an investigation of using the gamma ray beam of the ILC for additional applications, including nuclear physics. As a result of changing the collimator shape, as well as the parameters of the undulator magnets, we obtained spectra from numerical simulationsusingtheHUSR/GSRsoftwarepackage. Wepresent results from simulations and a discussion of possible future investigations in this paper.
