A proton has more bang for the buck than X-ray, so to say,
as it is heavier. Being a particle with some weight, it
is breaked in a rather small area where the energy is
deposited. Being a charged particle, it can be focused and
accelerated rather easily. Another option would be neutrons,
which are equally heavy. But they require a nuclear reactor
to produce them. And focussing is not trivial either.
