It was suggested to me to use particle type -6 (4-HELIUM) instead of
particle type -2 with Z=2 and A=4. I tried this and now my jobs appear
to be running.
Is it not possible to run Alphas with the particle type -2 (HEAVYION)?

Subject: Vacuum stopping error message with Alpha's
Dear FLUKA Forum,
I am trying to run a spectrum of alpha particles on an aluminum/silicon
target. The job quickly aborts with the following error message in both
my .err and .out files:
1NUMBER OF BEAM NUMBER OF BEAM APPROXIMATE NUMBER
AVERAGE TIME USED TIME LEFT (RESERVED NUMBER OF STARS
PARTICLES HANDLED PARTICLES LEFT OF BEAM PARTICLES BY A
BEAM PARTICLE 80.0 SECONDS CREATED
THAT CAN STILL BE
FOR PRINTOUT)
HANDLED
NEXT SEEDS: 0 0 0 0 0 0 12110
C 0 0
*** Vacuum stopping: Ij, Pla, Ekin -6 0. 0.
In the past, this file worked fine with FLUKA2003. The only difference
now is that I changed the source a little bit, which I don't think is
the problem. If you change the source type to any other heavy ion the
job appears to run fine. Below is my input file for reference. Any help
would be appreciated.
Sincerely,
Brandon Reddell
