Underdense relativistically thermal plasma produced by magnetically assisted direct laser acceleration
K. Weichman, J. P. Palastro, A. P. L. Robinson +1
We introduce the first approach to volumetrically generate relativistically thermal plasma at gas-jet--accessible density. Using fully kinetic simulations and theory, we demonstrat…
Towards the Optimisation of Direct Laser Acceleration
A. E. Hussein, A. V. Arefiev, T. Batson +13
Experimental measurements using the OMEGA EP laser facility demonstrated direct laser acceleration (DLA) of electron beams to (505 75) MeV with (140 30)~nC of charge fr…
Sign reversal in magnetic field amplification by relativistic laser-driven microtube implosions
K. Weichman, M. Murakami, A. P. L. Robinson +1
We demonstrate and explain the surprising phenomenon of sign reversal in magnetic field amplification by the laser-driven implosion of a structured target. Relativistically intense…
Generation of megatesla magnetic fields by intense-laser-driven microtube implosions
M. Murakami, J. J. Honrubia, K. Weichman +2
A microtube implosion driven by ultraintense laser pulses is used to produce ultrahigh magnetic fields. Due to the laser-produced hot electrons with energies of mega-electron volts…
Emission of electromagnetic waves as a stopping mechanism for nonlinear collisionless ionization waves in a high- regime
Haotian Mao, Kathleen Weichman, Zheng Gong +3
A high energy density plasma embedded in a neutral gas is able to launch an outward-propagating nonlinear electrostatic ionization wave that traps energetic electrons. The trapping…
Strong surface magnetic field generation in relativistic short pulse laser-plasma interaction with an applied seed magnetic field
Kathleen Weichman, Alexander P. L. Robinson, Masakatsu Murakami +1
While plasma often behaves diamagnetically, we demonstrate that the laser irradiation of a thin opaque target with an embedded target-transverse seed magnetic field $B_\mathrm{seed…
