摘要：

A polarized positron source is one of the key ingredients of a future linear collider. The source performance is decisive in order to reach the goals of the physics programme. But it is a challenge to develop a high-intensity polarized positron source, which meets the machine requirements. Simulation programs which can calculate expected yield, polarization are indispensable tools in these R&D projects. Based on the Geant4 framework a new tool, PPS-Sim (Polarized Positron Source Simulation), has been developed for design and optimization of a polarized positron source. This program is able to simulate common positron production mechanisms. It describes both the production of polarized positrons, and the spin transport in electromagnetic components in a single framework.
