This is an unmodified version of exercise 4 from the 2005 Cern School of Computing. With some cleanup it could be made into a introduction to SLIC/LCDD. The code for the exercise is attached.

Simulation, Visualization, and Analysis

Although SLIC can be used to set up arbitrarily complex detector geometries this typically involves more work than we have time for in this exercise, so instead you will set up a simple test calorimeter, corresponding to that described in this NIMA 487 (2002) 291-307. The detector you will set up consists of 18 layers, each 1m square in the xy direction, with 8mm of lead followed by 2mm of plastic scintillator in the z direction. The scintillator is read out using photomultipliers, and thus represent the "sensitive" part of the calorimeter. We will simulate the effect of firing electrons at various energies into the front of the calorimeter. The goal of the exercise is to write out a file containing the simulated "hits" in the sensitive layers, and then to analyze this file to determine the energy resolution of the calorimeter for various electron energies.
