When a positron (antimatter) annihilates with an electron (matter), their mass is converted to energetic photons. Information about the environment in which the electron annihilated is encoded into the emitted photons subject to conservation laws. Positron Annihilation Spectroscopy is the study of positron and electron interaction by careful measurement of photons emitted in the annihilation process.
This project can be adjusted to suite any level. However, a student(s) interested in or familiar with digital signal processing and machine learning algorithms would be ideal.
