Scatter

        / width(0) 
          particles(100000)                
          repeat(10)                
          targetfile()

Purpose

This is an "afterburner" to the 1D beam model. By means of Monte Carlo sampling using Moliere's multiple scattering theory, the beam broadening as a function of depth is evaluated and filed as a modified depth dose distribution (pencil beam).
Appropriate dE/dx tables as well as a spectrum data base must be loaded.

Parameters

beamenergy
Calculation for this energy (MeV/u).
targetfile()
Name of file with target material list. If omitted: H2O.
width(w)
Initial FWHM of the beam spot.
particles(p)
Number of particles to follow initially.
repeat(r)
Number of sample runs.
debug
Debug switch. Lots of output !

Remarks

Later

Examples

 spc * /delete
 spc "$TRIP98/DATA/RF3MM/*.spc" / read
 dedx $TRIP98/DATA/20040607.dedx /read
 scatter / energy(270) 
creates the pencil beam description for 270 MeV/u
