Abstract
The PM2D code is used to simulate relativistic electron-positron plasma generated in the target irradiated by laser light of relativistic intensities. The paper discusses results of PM2D simulations performed with the aim to increase mean energy and brightness of positron jets that could be formed near the rear surface of the target. The calculations demonstrate the possibility to significantly improve positron jet acceleration by target reconfiguring.
