Example
*******

The following example defines a multi-leaf tungsten collimator design
based loosely on that used with the Varian Millenium MLC.
Actual parameters are DIFFERENT - this serves just as a template.
Do not attempt to use these parameters for a simulation of the real
machine.

The collimator starts at Z=48.25 cm and has 60 tungsten leaves opening
in the X direction. Leaves 1-10 and 51-60 are FULL and leaves 11-50 are
TARGET/ISOCENTER pairs. The Z focus of the leaf sides is at Z=0 cm
which is the position of the source. The leaf ends are rounded with a
radius of 8 cm. In this example, leaf opening coordinates are chosen to
create a square of width ~ 2cm centred on the beam axis.

Electrons and photons in both the collimator and the opening regions
will be followed down to kinetic energies of 189 keV (ECUT=0.7,
PCUT=0.01). Dose deposited in the tungsten leaves will be stored
in dose zone 2, and dose deposited in the opening will be stored
in dose zone 1.
