Re: List of particles produced

  Dear Johannes,
  first of all, I would suggest to give a look at the informations
  that you get automatically at the end of each FLUKA run, in the
  part "Summary of the FLUKA run" of the file [].out.
  There you find already the list of all produced particles:
   - the list of secondaries, that are generated in inelastic interactions;
   - the list of secondaries, that are generated as decay products.
  All the numbers you find are given per beam particle, together with the
  relative abundance.

  Since you are sending a proton beam on a copper target, I guess that you
  could be interested to get the list of the particles, that emerge
  from your target.
  In this case you could use the MGDRAW user routine: in the BXDRAW
  entry (that you activate by using the USERDUMP card with what(3)<7,
  see online manual,13.2.13) you can save the information about
  the kind of particle, that crosses the boundary between the copper
  and the region around, through the variable Jtrack in the common TRACKR.

  The use of MGDRAW, however, is for expert users. If it is straightforward
  to list all the kind of particles emerging from your target, on the other
  hand you have to be careful with the numbers you evaluate: the secondary
  particle you are following could have a weight different from 1 (i.e.
  in case you are using the BIASING option, or in the multigroup treatment
  of low energy neutrons, below 20 MeV).
  You have then to save also the variable Weight (always in the TRACKR
  common).

  If you want to calculate the yield - as double differential
  distribution, in energy and solid angle - of secondary particles, that
  come out from your target, it is recommended to use cards like USRBDX or
  USRYIELD, as you probably already know.

  Hope it helps..
   cheers
    Anna
