Two main types of target were prepared: thin (2 mu m) foils and thick (500 mu m) slabs. Such targets were irradiated with a sub-nanosecond, kJ-class laser with a moderate intensity (similar to 10(16) W/cm(2)) to trigger the p(B-11, alpha)2 alpha nuclear fusion reaction thanks to the acceleration of proton streams with energy of 0.1-1 MeV. The combination of the ad-hoc developed targets and the given laser pulse parameters allowed to generate a very high flux of alpha particles (10(7)-10(9)/sr per shot).
The paper mainly focuses on microfabrication techniques and processes optimized for the fabrication of such advanced targets and on a comparison of the key results achieved with the different targets used in the experiment. Hydrodynamic simulations are also discussed.
