GEANT4 Emittance Diagnostics Simulations for the ERL Injector Prototype

The injector for the Energy Recovery Linac, a new high energy X-ray source under design at Cornell, will need to create ultra bright electron beams. One measure of this brightness, the transverse emittance, is the single most important characteristic of these beams. It is therefore crucial to be able get an accurate measure of this quantity. Two experimental designs to perform this measurement have been proposed and have been examined using computer simulation.
