Abstract

A model has been created in Geant4 [1] to simulate the key elements of an undulator-based positron source for CLIC: the goal is to consider such a source as an alternative to the present baseline concept. The parameters of the undulator and capture device need to be adjusted to cover a range of operating scenarios. We report the results of calculations for two specific operating scenarios, for the rate of positron production, positron polarisation, and capture efficiency.
