At present you cannot obtain directly a Bragg peak using flair.
It is right to use USRBIN but, inside flair, we
we have not a tool to plot a 1-dimensional plot of the kind
deposition vs depth from a USRBIN output.
I do it with other tools and I give here an exmple
In attachment you can find a bragg.inp input file to calculate naively the
energy deposition in water from C-12 projectiles (you need FLUKA linked
witk rqmd and dpmjet). There I define a water target and by means of
USRBIN I superimpose a grid of 100 equally spaced bins along the beam
direction (Z). Actually there are 2 USRBIN detectors. One is just energy
deposition (on unit 22) and the other (on unit 24) is weighted with a
comscw.f routine to define the dose in Gray (also attached here).
After the run and the sum of fort.22 and fort.24 files (that you can do
with flair), by means of $FLUPRO/flutil/usbrea I obtain an ascii file
from the USRBIN sum. Now you can access such an ascii file with other
For instance, if you are accustomed to the ROOT package, I attach here
a macro called readusb.C that is used as follows.
a) you call root from the directory where the ascii file is located
b) within root you issue the command: .x readusb.C
c) you will be prompted with the name of the ascii file
d) you get your plot as shown in the bragg.eps attachment
A tool to make a similar plot will be soon added to a next version of
