Paper Abstract

This paper proposes a new method of proton acceleration. A slow plasma wave produced by backward Raman scattering captures slow protons injected. A density gradient of a plasma enables the wave phase velocity to increase as the proton test beams are accelerated. Preliminary results of PIC simulations of the backward scattering are presented in constant and tapered-density plasma. A proof-of-principle experiment is proposed using a T3 laser and test beams from a Van de Graaf accelerator, in which a 500 mJ laser will give acceleration gain of approximately 50MeV in a distance of 500 micrometers .
