Detailed Description

Detector construction class to define materials and geometry. The drift tube is a cylinder made of Al filled with Ar/CO2. It has a thin window on the base that is adjacent to the absorber plate. In the center of the cylinder is the anode wire made from Tungsten.

The primary particles interact in the absorber and produce secondary particles, which enter the drift tube via the thin window.
