Abstract

The factors affecting the acceleration process of interaction between double plasma targets and the ultraintense linearly polarized laser pulse has been studied in this work. The results show that extra electrons provided by the pre-target play important roles in enhancing the longitudinal bipolar field and better confining of the protons from the main-target. Besides, there exists great difference between s- and p-polarizations of the laser pulse for distinguished transverse effects. By contrast to the case of circularly polarized laser pulse, higher areal density ratio of pre-target to main-target is needed to achieve efficient plasma block acceleration driven by the linearly polarized one. Finally, monoenergetic proton beam has been obtained via double targets driven by a linearly polarized laser pulse, which has better collimation, monochromaticity and stability, as well as higher energy conversion efficiency.
