Transition radiation detector

Transition radiation detector

A transition radiation detector (TRD) is a particle detector utilizing the gamma-dependent threshold of transition radiation in a stratified material. It contains many layers of materials with different indices of refraction. At each interface between materials, the probability of transition radiation increases with the relativistic gamma factor. Thus particles with large gamma give off many photons, and small gamma give off few. For a given energy, this allows a discrimination between a lighter particle (which has a high gamma and therefore radiates) and a heavier particle (which has a low gamma and radiates much less).
