“…CR39 nuclear-track diagnostics. In order to detect the produced alpha particles, two CR39 detectors 49,50 were located at the front side of the target in each experimental run. One was placed slightly above the equatorial plane and the other one below it to assure the detection of ions by the FC.…”

Nuclear fusion between protons and boron-11 nuclei has undergone a revival of interest thanks to the rapid progress in pulsed laser technology. Potential applications of such reaction range from controlled nuclear fusion to radiobiology and cancer therapy. A laser-driven fusion approach consists in the interaction of high-power, high-intensity pulses with H- and B-rich targets. We report on an experiment exploiting proton-boron fusion in CN-BN targets to obtain high-energy alpha particle beams (up to 5 MeV) using a very compact approach and a tabletop laser system with a peak power of ~10 GW, which can operate at high-repetition rate (up to 1 kHz). The secondary resonance in the cross section of proton-boron fusion (~150 keV in the center-of-mass frame) is exploited using a laser-based approach. The generated alpha particles are characterized in terms of energy, flux, and angular distribution using solid-state nuclear-track detectors, demonstrating a flux of ~105 particles per second at 10 Hz, and ~106 per second at 1 kHz. Hydrodynamic and particle-in-cell numerical simulations support our experimental findings. Potential impact of our approach on future spread of ultra-compact, multi-MeV alpha particle sources driven by moderate intensity (1016-1017 W/cm2) laser pulses is anticipated.

“…The standard procedure when using solid-state nuclear track detectors (SSNTD) is to reveal latent ion tracks by operating a chemical etching which makes them visible under the optical or atomic force microscope. Commonly used etching solutions in the literature are alkaline etchant such as NaOH or KOH with concentration range of 6-7 N at temperatures of 60-70 °C [1][2][3][4][5][6][7][8][9][10]. However, a new etchant solution composed of NaOH with different amounts of alcohols (ethanol and/or methanol) has been used as a strong and active etchant [11][12][13].…”
