Monoenergetic acceleration of charge-neutralized ion bunches to GeV-scale energies by the combination of a high-current electron beam and an ionization front
Jiyuan Chen, Jihoon Kim, Roopendra Singh Rajawat +1
Compact heavy ion accelerators have numerous applications, ranging from heavy ion fusion to carbon ion radiotherapy, and testing radiation-hardened electronics. The demand could be…
Simultaneous amplification and shaping of excimer lasers using Stimulated Brillouin Scattering in the strongly damped limit
Jihoon Kim, Roopendra Rajawat, Polina Blinova +6
Attaining practical Inertial Fusion Energy (IFE) depends on how efficiently one can couple the driver energy to the nuclear fusion fuel for compression and ignition. While the exci…
Analytic model of stable shock-like structures in laser interaction with underdense plasma for identifying of phase and polarization dependent regime of laser wakefield accelerators
Junjue Liao, Jihoon Kim, Gennady Shvets
We present an analytical model describing a stable shock-like structure that is formed when an ultra-intense laser propagates through an underdense plasma. It is shown that such st…
Acceleration and focusing of multispecies ion beam using a converging laser-driven shock
Jihoon Kim, Roopendra Rajawat, Tianhong Wang +1
We demonstrate an ion acceleration scheme capable of simultaneously focusing and accelerating a multispecies ion beam with monoenergetic spectra to a few micron radius. The focal l…
Effects of Laser Polarization and Color on Hybrid Laser Wakefield and Direct Acceleration
Xi Zhang, V. Khudik, A. C. Bernstein +2
We demonstrate that hybrid laser wakefield and direct acceleration (LWDA) can be significantly improved by using two laser pulses with different polarizations or frequencies. The i…
Wake excited in plasma by an ultra-relativistic point-like bunch
G. Stupakov, B. Breizman, V. Khudik +1
A plasma flow behind a relativistic electron bunch propagating through a cold plasma is found assuming that the transverse and longitudinal dimensions of the bunch are small and th…
Beyond the ponderomotive limit: direct laser acceleration of relativistic electrons in sub-critical plasmas
A. V. Arefiev, V. N. Khudik, A. P. L. Robinson +3
We examine a regime in which a linearly-polarized laser pulse with relativistic intensity irradiates a sub-critical plasma for much longer than the characteristic electron response…
Simulations of stable compact proton beam acceleration from a two-ion-species ultrathin foil
T. P. Yu, A. Pukhov, G. Shvets +4
We report stable laser-driven proton beam acceleration from ultrathin foils consisting of two ion species: heavier carbon ions and lighter protons. Multi-dimensional particle-in-ce…
