Projectile/element file format
Projectile/element files have two purposes.
At first, they define the projectiles and their properties
available for the simulation.
Second, they define the chemical elements for the
target material (de)composition.
The usual file name extension is .proj
.
Example.
File version 20090415
For TRAX
versions > 0804.
!filetype trxproj
!fileversion <yyyymmdd>
!filedate <dow> <mmm> <dd> <hh>:<mm>:<ss> <yyyy>

name
can be e-
, e+
or
n
for electrons, photons, and neutrons, respectively.
Note, however, that photon and neutron interactions
or not yet implemented in this version.
For ionic projectiles name
is the generic element symbol.
The nuclides of a particular element are characterized by
charge, Z
,
mass number, A
,
mass relative to the mass standard (12C), Mr
,
and natural abundancy (in percent).
RMSc
and RMSi
denote the nuclear charge and interaction radius,
respectively. If RMSi
is omitted, RMSc
is taken.
If both are omitted, an internal formula is applied:
RMS = 1.36 A ^ (1/3)
For other projectiles (electrons, photons, neutrons)
these entries are only formal, since they are filled internally.
TRAX
versions > 0804
come with a complete database of supported projectiles in the
PROJ
subdirectory.
