Only theory.

Yes. I have read about this a few years ago.

cross-section for the fusion reaction is small and lots of energy is
wasted accelerating particles (p,D,T) that will never react and
produce energy. If they react the generated MeV are unable to
compensate this waste.
Maybe with the fine-tuning of the beams energy the cross-section
could be high enough to make the energy gain usable but I doubt it.
