Abstract
A method for generation of quasimonoenergetic, low emittance fast ion/nuclei bunches of solid densities from nanotargets by two counterpropagating laser pulses of ultrarelativistic intensities is proposed, based on the threshold phenomenon of particles reflection due to induced nonlinear Compton scattering. Particularly, a setup is considered which provides generation of ion bunches with parameters that are required in hadron therapy.
Highlights
Acceleration of ions with superstrong laser beams and their interaction with the matter at extreme conditions in ultrashort space-time scales have attracted broad interest over the last few years conditioned by a number of important applications, such as generation and probing of highenergy-density matter [1], inertial confinement fusion [2], isotope production [3], hadron therapy [4], etc
There are several regimes of ions acceleration depending on the laser intensity: target normal sheath acceleration regime [5], Coulomb explosion regime [6], radiation pressure dominant regime [7], and the shock wave acceleration mechanism [8]
In this paper we propose a method for generation of solid density, monoenergetic, and low emittance ion/nuclei bunches of ultrashort durations
Summary
Acceleration of ions with superstrong laser beams and their interaction with the matter at extreme conditions in ultrashort space-time scales have attracted broad interest over the last few years conditioned by a number of important applications, such as generation and probing of highenergy-density matter [1], inertial confinement fusion [2], isotope production [3], hadron therapy [4], etc. Most of these mechanisms are based on the indirect processes, when ions are accelerated by the space-charge fields induced in the laser-target interaction process. In the paper [13], it has been considered a combination of the laser-plasma mechanism as a proton source with the postacceleration employing single
