abstract

The use of solid boron hydride molecules as a fuel for proton-boron fusion was proposed by M. Kr\r{u}s and M. Londesborough at "Interaction of Inorganic Clusters, Cages, and Containers with Light" workshop in November 2021. Here we demonstrate experimentally, for first time, that the solid boron hydride, octadecaborane - \textit{anti}-B${}_{18}$H${}_{22}$, produces a relatively high yield of alpha particles of about $10^9$ per steradian using a sub-nanosecond, low-contrast laser pulse (PALS) with a typical intensity of $10^{16}$ Wcm${}^{-2}$. In contrast to previously published proton-boron studies, the boron hydrides, due to their composition containing only atoms of boron and hydrogen, represent a natural choice for future proton-boron nuclear fusion schemes.

  1. Interaction of Laguerre-Gaussian laser pulses with borane targets of different hydrogen-boron ratio

    physics.plasm-ph 2025-04 conditional novelty 4.0 of 10

    In particle-in-cell simulations, boron-rich hydrogen-boron targets generate stronger axial magnetic fields from a Laguerre-Gaussian pulse than hydrogen-rich targets, while hydrogen-rich foils produce faster protons.
