Title: e+e- Plasma Photon Source

This note addresses the idea of a photon source that is based on an e+e- plasma created by co-propagating beams of e+ and e-. The plasma has a well-defined temperature, and the thermal distribution of the charged particles is used to average over the relative velocity cross section multiplied by the relative velocity. Two relevant cross sections are the direct “free-free” annihilation of e+e- pairs in the plasma, and the radiative recombination of e+e- pairs into positronium (Ps) which subsequently undergoes annihilation.
