 		      Geant4 - Brachytherapy example
     =========================================================

                             README
                      ---------------------

0. Introduction.

Brachytherapy example simulates energy deposition on a voxel grid
for a Ir   brachytherapy source.

1. Technical description

1.0. the  source is constructed in the 
brachyDetectorConstruction class. The source is composed by
an iridium  core encapsulated in a capsule (body + tip). 
The source is put in the center of a 30*cm water box.

1.1. The water box is made sensitive detector. A longitudinal slice
of it is associated to a planar read out geometry. At every hit
energy deposition is read and stored in a 2D histogram.

1.2. the  output is  the file  brachy2.hbk  
(e.g. anysotropy and isodose calculations):
 1)1Dhistogram with the spectrum of initial energy of gamma
 2)2Dhistogram with the distribution of energy in the plane (x,z,energy)
2. Make

1.3.the default visualization is with Dawn 

A standard Geant4 example GNUmakefile is provided.

2. Usage

 run "Brachy" executable. 
The framework in in interactive mode,so
you have to do:
idle>/run/beamOn ( numberofevents)

The output is ("brachy2.hbk")

before running remenber to delete *.hbk

in the file brachy.py there are the instructions  to visualize the histograms with the old version of Lizard;

in order to do that open another lxplus with egcs-2.91.66 and make:
source /afs/cern.ch/sw/lhcxx/share/LHCXX/3.6.3-sec/install/sharedstart.csh
then digit lizard in the directory where brachy3.hbk is and then follow the instruction of the brachy.py
