Purpose

Handles external cross section tables necessary for beam modeling. At present only nuclear fragmentation is supported. The format of the external tables is described here.

Parameters

items
For calculate: list of projectiles (nuclide symbols), enclosed in apostrophes '.
For read: list of external files, might include wildcards.
targets
For calculate only: list of target nuclei (nuclide symbols), enclosed in apostrophes '.
iactions
For calculate only: list of interactions, enclosed in apostrophes '. Currently only the default, nf, is supported.
calculate
Calculates cross sections.
model()
For calculate only: selects cross section model. Currently only the default is supported.
energy(lo,hi)
For calculate only: selects energy range (MeV/u) to be calculated.
ne()
For calculate only: selects number of energy table breakpoints.
eps()
For calculate only. Not yet implemented
write
Writes the calculated cross sections into as many files as there are target nuclei.
File naming conventions:
<prefix><targ>nf.xs
where <targ> are the nuclide symbols of the target nuclei.
(prefix)
export(fmt)
Exports the calculated tables in some non-native format, at present only <fmt>="gd" is implemented to export for the gd plot program. File naming convention is:
<prefix><targ>nf.xs.gd
where <targ> are the nuclide symbols of the target nuclei.
(prefix)
prefix()
Output path for the calculated tables. It is just a prefix put in front of the file naming convention. Might be a directory or just part of a file name.
read
Reads external cross sections from files specified in the item list.
read
Not yet implemented.
delete
Deletes cross section tables. In the current release filtering is not implemented, so everything is deleted.
debug
Debug switch. Lots of output !

Remark

This is a preliminary implementation, some algorithms might be subject to future changes, e.g. selection of fragments and energy break points to be calculated.
