Relativistic Multistage Laser Ion Acceleration

Introduction •A relativistic calculation to determine the ion velocity and energy of second stage of ion acceleration has been done. •A fully relativistic 1D3V PIC simulation using LPIC++ has been done. • Results from PIC simulations validate our relativistic calculation for multistage acceleration. • It has been found that relativistic results differ a lot from non-relativistic calculations at higher intensities and hence is inevitable. • Further, 3D PIC simulations are performed to establish the feasibility of this process.
