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 (∼1–2 J)
nanosecond vacuum discharge with a virtual cathode, the field of which accelerates protons and boron ions to
the energies required for pB synthesis (∼100–300 keV) under oscillating ions’ head-on collisions. The yields
of α 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 α particles of about 5 × 104/4π was
obtained during the pulse-periodic operation of the generator within total 4 μs of the high voltage applied, which
is ∼10 α particles/ns.
