Development of an Electron-Positron Source for Positron Annihilation Lifetime Spectroscopy

Abstract

Laser intensities capable driving relativistic phenomena are delivered in a single-wavelength spot size on solid targets producing energetic electrons for positron production. This program has accomplished the production of >1 MeV electron energies with laser pulse energy of ~ 1mJ at 500Hz repetition rate. The properties of the laser, diagnostics and the energetic electron emission are discussed. Application of the laser-produced plasma phenomena to positron generation is discussed and future directions are briefly stated.
