Dear Biagio,
here is the meaning of the variables in EMFSTK as far as I know. Note
however that for some of the variables I had to guess from the
corresponding ones with a similar name in (FLKSTK).
(Alfredo please check!)
ETEMF = total energy in MeV
PMEMF = momentum in MeV/c
XEMF, YEMF, ZEMF = particle coordinates (cm)
UEMF, VEMF, WEMF = particle direction cosines
DNEAR = safe distance from the nearest boundary (cm)
UPOL, VPOL, WPOL = direction cosines of the polarization vector
USNRML, VSNRML, WSNRML = direction cosines of a (possible) surface normal
WTEMF = particle weight
AGEMF = particle age (s)
CMPEMF = cumulative path travelled by the particle (cm)
ESPARK = array of spare real variables available for the user
RDLYEM = delay in production with respect to the nominal primary "0"
time for a particle produced in radioactive decays (s)
IESPAK = array of spare integer variables available for the user
ICHEMF = particle charge (+1: positron, -1: electron, 0: photon)
IREMF = region number
IRLATT = lattice cell number
NHPEMF = pointer to the history object (Geant4 geometry)
LLOEMF = generation number
LOUEMF = user flag
LRDEMF = flag for particles generated in radioactive decays
NPEMF = stack pointer
NPSTRT = stack pointer of the last processed particle
Yes, in the EMF part of FLUKA energies and momenta are in MeV and MeV/c,
for historical reasons. A conversion from and to GeV and GeV/c is done
at the interface with the calling routines.
