The irradiation of arrays of aligned deuterated polyethylene nanowires (CD2) with ultra-high contrast femtosecond laser pulses of relativistic intensity was recently shown to accelerate deuterons to multi-MeV energy and to efficiently produce quasi-monoenergetic fusion neutrons [1]. The number of fusion neutron produced exceeds by > 500 times that produced by irradiating flat solid CD2 targets under the same conditions. Those experiments were conducted at irradiation intensities below 1 x 10 20 W cm-2 .
Here we present the first results of deuteron acceleration from nanowire experiments conducted at irradiation intensities of ~ 2x1021 W cm-2. The deuterons are measured to be accelerated to energies of several tens of MeVs and to be emitted in a cone of approximately 10 degrees half-angle. 3-D fully relativistic particle in cell computations are used to elucidate the mechanisms of ions acceleration in the nanowire arrays.
