Structure Diagram for PMT:  PMT Simulation
                  ==========================================
 
         An Introduction to the Structure Diagrams is available.

Introduction
------------
 
It is, in effect, a complete Monte Carlo of a single PMT.  Indeed it was
developed as such.  It deals with all aspects of an individual PMT:-
 
o    The response.
 
o    The internal geometry.
 
o    Internal photon transport.
 
Probably the only reason for selecting this within a user application is to
extend the range of the GEO SU (q.v.).
