One of the challenges of aneutronic fusion is the fact that it uses a Hydrogen-Boron reaction for fuel, rather than the more traditional deuterium-tritium fusion reaction.
An alternative is Inertial confinement fusion (ICF), in which fusion of nuclei is initiated by heating and compressing a fuel target, typically in the form of a pellet containing deuterium and tritium contained in a device called a hohlraum (hollow space or cavity) using an extremely powerful laser.
