IONTRANS

Summary

Determines the transport of ions (A < 1), allowing to limit it to subsets of light ions (A > 5) and to choose between approximate and full transport (including nuclear interactions) ​​​​

​

WHAT(1) ≥ 1.0:

no transport, full or approximate, of any light or heavy ion

= 0.0:

ignored

= -1.0:

approximate transport (without interactions) of all light and heavy ions

= -2.0:

full transport of all light and heavy ions

-6.0 ≤

 WHAT(1) ≤ -3.0: full transport of light ions with FLUKA id ≥ WHAT(1)

(-3 = d, -4 = t, -5 = \(^3\)He, -6 = \(^4\)He), and approximate transport of all other ions

Default

= 0.0  (no ion transport, unless a ion beam is requested by the BEAM card, see Note 2)

WHAT(2)

– WHAT(6): not used

SDUM

: not used

Notes

1. When requested, interactions at energies larger than 125 MeV/n are performed provided that the external event generators DPMJET and Rqmd ​​ are linked (through the script $FLUPRO/flutil/ldpmqmd). For energies lower than 125 MeV/n, the Bme​ event generator is already included in the main $FLUPRO/libflukahp.a library and linked in the standard $FLUPRO/flukahp executable.

2. In the presence of a heavy ion beam, full transport of all ions is enabled by default (no need for IONTRANS).
