Hello
BEAMPART means particle with generation number equal to 1, independently
on the particle type.
The generation number is set to 1 in the source routine, either standard
or user-written.
It increases when particles undergo inelastic interactions or decay. It
does not change after elastic interactions, except for groupwise low
energy neutrons where it always changes.
Hope this helps
