Description

Positron and Positronium Collision Dynamics. Positron and positronium collisions are processes of both fundamental and applied importance. The positron is the antiparticle of the electron and together they can form a bound state, called positronium. Positrons and positronium are important for understanding fundamental collision processes, as well as astronomy, materials physics and medical physics. In particular, widely used Positron Emission Tomography (PET) scans rely on an understanding of positron and positronium collisions to properly account for image quality and radiation damage. This project aims to use high-fidelity beams of positrons and positronium to investigate collision processes and enable the development of transport models to better understand positron dosimetry..
