ILC Positron Production Target Simulation

/ Abstract
A photon-positron conversion target of the undulator or laser based polarized positron source is optimized using a modified GEANT-3 program adapted to count the spin transfer. High intensity positron beam with around 0.75 polarisation could be achieved choosing tungsten conversion target of 0.3 and 0.7 radiation lengths for the undulator and laser case respectively.
