Weibel- and non-resonant Whistler wave growth in an expanding plasma in a 1D simulation geometry
M E Dieckmann, L Palodhi, C Fegan +1
Ablating a target with an ultraintense laser pulse can create a cloud of collisionless plasma. A density ramp forms, in which the plasma density decreases and the ion's mean speed…

M E Dieckmann, Q Moreno, D Doria +7
The expansion of a thermal pressure-driven radial blast shell into a dilute ambient plasma is examined with two-dimensional PIC simulations. The purpose is to determine if laminar…
Expansion of a radial plasma blast shell into an ambient plasma
M E Dieckmann, D Doria, H Ahmed +6
The expansion of a radial blast shell into an ambient plasma is modeled with a particle-in-cell (PIC) simulation. The unmagnetized plasma consists of electrons and protons. The for…

B. Dromey, L. Stella, D. Adams +22
Direct investigation of ion-induced dynamics in matter on picosecond (ps, 10-12 s) timescales has been precluded to date by the relatively long nanosecond (ns, 10-9 s) scale ion pu…
