All-optical trapping and acceleration of heavy particles
A scheme for fast, compact, and controllable acceleration of heavy particles
in vacuum is proposed, in which two counterpropagating lasers with variable
frequencies drive a beat-wave structure with variable phase velocity, thus
allowing for trapping and acceleration of heavy particles, such as ions or
muons. Fine control over the energy distribution and the total charge of the
beam is obtained via tuning of the frequency variation. The acceleration scheme
is described with a one-dimensional theory, providing the general conditions
for trapping and scaling laws for the relevant features of the particle beam.
Two-dimensional, electromagnetic particle-in-cell simulations confirm the
validity and the robustness of the physical mechanism.Comment: 10 pages, 3 figures, to appear in New Journal of Physic
Prospects for all-optical ultrafast muon acceleration
A scheme for fast, compact, and controllable acceleration of heavy particles
in vacuum has been recently proposed [F. Peano et al., New J. Phys. 10 033028
(2008)], wherein two counterpropagating laser beams with variable frequencies
drive a beat-wave structure with variable phase velocity, leading to particle
trapping and acceleration. The technique allows for fine control over the
energy distribution and the total charge of the accelerated beam, to be
obtained via tuning of the frequency variation. Here, the theoretical bases of
the acceleration scheme are described, and the possibility of applications to
ultrafast muon acceleration and to the prompt extraction of cold-muon beams is
discussed.Comment: 12 pages, 5 figures, to appear in Plasma Physics and Controlled
