  1 In this example, the particle fluence is evaluated for a simple set-up,
  2 consisting of one target solid cylinder, with axis along the z-direction,
  3 and a beam particle shot before the target along the axis of the target.
  4 
  5 The particle fluence is computed in three places: "upstream", "downstream"
  6 and "side", defined as the positions immediately after, before and aside,
  7 respectively, of the target with respect to the direction of the primary
  8 particle.
  9 
 10 The particle fluence is estimated by summing the track length in a
 11 "scoring volume" - i.e. a thin cylinder (for "upstream" and "downstream"
 12 cases) or a thin hemisphere shell (for the "side" case) filled up with
 13 G4_Galactic (very low density gas) material, immediately outside the
 14 target - and then dividing for the cubic volume of such scoring volume.
 15 
 16 Complementary information on average multiplicity, average kinetic energy,
 17 and average total energy flow (i.e. sum of kinetic energies) for the
 18 particles produced in the target are also computed.
 19 
 20 The particle fluence is evaluated for the following 11 particle types:
 21 -  all
 22 -  electron + positron 
 23 -  gamma
 24 -  muon- + muon+
 25 -  neutrino (any flavour and including anti-neutrino)
 26 -  charged pions
 27 -  neutron + anti_neutron
 28 -  proton + anti_proton
 29 -  ion (and anti-ions)
 30 -  otherMeson (e.g. kaons, etc.)
 31 -  otherBaryon (e.g. hyperons, etc.)
 32 
 33 The particle fluence is evaluated for the following 3 kinematical ranges:
 34 -  any kinetic energy
 35 -  kinetic energy < 20 MeV
 36 -  kinetic energy > 20 MeV
 37 
 38 Look for the string "***LOOKHERE***" for those parameters/options that
 39 are either hardwired in the code (i.e. not available via UI command),
 40 or default values of UI commands.
 41 
 42 This example uses the physics list factory, therefore you can specify
 43 the reference physics list you want to use via the PHYSLIST
 44 environmental variable (by default, if you don't set it, the FTFP_BERT
 45 physics list is used).
 46 
 47 To build this example:
 48 
 49   mkdir Build; cd Build
 50   cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo \
 51         -DGeant4_DIR=/path-to-geant4-libraries ../.
 52   make
 53 
 54 To run it:
 55 
 56   ./Layer all_together.in
 57 
 58 which shoots 50 GeV pion- on different target materials, 100 events
 59 in each run, and print out some information on the particle fluence
 60 at the end of each run.
 61 Other macros exist for specific materials:
 62 cu.in, fe.in, graphite.in, lar.in, pb.in, pbwo4.in, polystyrene.in, si.in, w.in .
