Abstract
The object of this thesis work was to develop a (Monte Carlo) simulation package that can be used to aid in the design of the Timed Photon Counter (TiPC). The TiPC is a single photon detector whose working principle is based upon the multiplication of an electron signal by transmission dynodes, or tynodes. For TiPC to be feasible, it is necessary to develop tynodes that have a secondary electron yield of more than 4, preferably with a primary electron energy as low as possible.
