| 内容記述 | Dense high-energy monoenergetic proton beams are vital for wide applications, thus modern laser- plasma-based ion-acceleration methods are aiming to obtain high-energy proton beams with energy spread as low as possible. In this work, we put forward a quantum radiative compression method to postcompress a highly accelerated proton beam and convert it to a dense quasimonoenergetic one. We find that when the relativistic plasma produced by radiation-pressure acceleration collides head on with an ultraintense laser beam, large-amplitude plasma oscillations are excited due to quantum radiation reaction and the pondero- motive force, which induce compression of the phase space of protons located in its acceleration phase with negative gradient. Our three-dimensional spin-resolved quantum electrodynamics (QED) particle-in- cell simulations show that hollow-structure proton beams with a peak energy approximately GeV, relative energy spread of few percents, and number Np ∼ 1010 (or Np ∼ 109 with a 1% energy spread) can be pro- duced in near-future laser facilities, which may fulfill the requirements of alternative applications, such as, for radiography of ultrathick dense materials, or as injectors of hadron colliders. | |||||
