Title: Collisionless shock acceleration of narrow energy spread ion beams from mixed species plasmas using 1 μ m lasers

Abstract

Collisionless shock acceleration of protons and C6+ ions has been achieved by the interaction of a 1020 W/cm2, 1 μm laser with a near-critical density plasma. Ablation of the initially solid density target by a secondary laser allows for systematic control of the plasma profile. This enables the production of beams with peaked spectra with energies of 10 – 18 MeV/amu and energy spreads of 10%–20% with up to 3 × 109 particles within these narrow spectral features. The narrow energy spread and similar velocity of ion species with different charge-to-mass ratios are consistent with acceleration by the moving potential of a shock wave. Particle-in-cell simulations show shock accelerated beams of protons and C6+ ions with energy distributions consistent with the experiments. In conclusion, simulations further indicate the plasma profile determines the trade-off between the beam charge and energy and that with additional target optimization narrow energy spread beams exceeding 100 MeV/amu can be produced using the same laser conditions.

FIG. 1 FIG. 1: (Color online) a)Experimental setup. A near-critical density target is created by first irradiating a Mylar foil with an ablation laser. After the target has expanded for a time $\tau$ , a high-intensity ps duration laser pulse is focused onto the target to produce the electrostatic shock wave. Acceleratedmore » ions are measured by the imaging magnetic spectrometer (IMS) and Thomson parabola (TP). TP measurements indicate the majority of accelerated ions are C6+/O8+. Accelerated electrons are measured by a permanent magnet electron spectrometer. Radiochromic film (RCF) was used to measure a portion of the spatial beam profile. Orthogonal to the target, a probe laser was used to measure the target expansion. Accelerated proton spectra shown for b) an unablated foil, and c-e) at different time delays from consecutive shots. The inferred peak ne of the target and laser a0 are also denoted. Only signal > 4× the background variation is shown.« less
