Abstract
We study the radiation damping effect on the relativistic acceleration of electron-positron plasmas with two-and-half–dimensional particle-incell(PIC) simulation. Particles are accelerated by Poynting flux via the diamagnetic relativistic pulse accelerator(DRPA), and decelerated by the self-consistently solved radiation damping force. With Ωce/ωpe ≥ 10, the Lorentz factor of the highest energy particles reaches γ > 100, and the acceleration still continues. The emitted radiation is peaked within few degrees from the direction of Poynting flux and strongly linearly polarized, which may be detectable in γ-ray burst(GRB) observations. We also show that the DRPA is insensitive to the initial supporting currents.
