0008 <!-- Short description of what this package is supposed to provide -->
0009
0010 The goal is to prepare fastsim for the upgrade of the pixel detector. A new, configurable interface for the geometry of the fastsim tracker was developed. To this end, it was necessary to also write a new algorithm for the propagation of the particles inside the tracker.
0011 The package is created inside it's own namespace so none of the standard fastsim code is affected. This allows for easy comparison/validation of the new geometry/particle propagation.
0012
0013 The geometry of the detector used to be hard-coded but can now be specified in a single python file (FastSimulation/Geometry/python/TrackerMaterial_cfi.py)
0014
0015 Motivation for a new algorithm (particle propagation inside the tracker)
0016 - almost impossible to adjust the old algorithm to the new, configurable geometry (hard-coded links have to be omitted)
0017 - old algorithm is flawed
0018 - the new algorithm allows to put material and instruments on any plane perpendicular to z, or on any cylinder with the z-axis as axis
0019 - while the old algorithm, with the requirement of nested layers, forbids the introduction of long narrow cylinders, required for a decent simulation of material in front of HF
