Description
We report an enhanced X-ray generation scheme based on the interaction of the PW-class pulses with a T-shaped overdense target, developing the previously suggested peeler scheme for acceleration of monoenergetic ion bunches. Including the reflective mirror segment of the target, the advantage of the scheme relies on a large number of electrons being accelerated to highly relativistic energies by a diffracted laser pulse and by the surface plasma wave colliding with the reflected laser pulse. This nonlinear Compton scattering mechanism greatly increases both energy and the number of emitted photons, compared to contemporary techniques. Our research has been conducted by means of large-scale numerical simulations with a 3D particle-in-cell code SMILEI with its radiation module.
