Abstract

The Compton Effect 1 is an ideal physics experiment for the advanced modern physics lab. The relevance of this experiment and an approach to teaching about this lab are discussed. The apparatus for this experiment consists of a Cs-137 gamma source located in a lead howitzer, a goniometer to precisely locate a NaI detector at different angles to make gamma energy measurements, and a multichannel analyzer system that includes a high voltage supply and amplifiers. The lead howitzer and goniometer were specially constructed, and information to reproduce them is given. Typical results are presented.
