| Popis: | We present the results of experiments on the aneutronic fusion of proton-boron (pB) in a single miniature device with electrodynamic (oscillatory) plasma confinement. The device is based on a low energy $(\ensuremath{\sim}1--2 \mathrm{J})$ nanosecond vacuum discharge with a virtual cathode, the field of which accelerates protons and boron ions to the energies required for pB synthesis $(\ensuremath{\sim}100--300 \mathrm{keV})$ under oscillating ions' head-on collisions. The yields of $\ensuremath{\alpha}$ particles registered for different conditions of the experiment are presented and discussed in detail. The experiment was preceded by particle-in-cell modeling of main processes accompanying pB reaction within the framework of the full electromagnetic code karat. The summary yield of $\ensuremath{\alpha}$ particles of about $5\ifmmode\times\else\texttimes\fi{}{10}^{4}/4\ensuremath{\pi}$ was obtained during the pulse-periodic operation of the generator within total $4\phantom{\rule{4pt}{0ex}}\ensuremath{\mu}\mathrm{s}$ of the high voltage applied, which is $\ensuremath{\sim}10\phantom{\rule{4pt}{0ex}}\ensuremath{\alpha}$ particles/ns. |
