OTR interferometry diagnostic for the A0 Photoinjector

OTR interferometry (OTRI) is an attractive diagnostic for investigation of relativistic electron beam parameters. The diagnostic is currently under development at the A0 Photoinjector. This diagnostic is also applicable for NML accelerator test facility that will be built at Fermilab. The experimental setup of the OTR Interferometer for the FNAL A0 Photoinjector is described in the report. Results of simulations and measurements are presented and discussed.
