Advances in Optical Transition and Diffraction Radiation Emittance Diagnostics

Optical transition radiation and optical diffraction radiation interferometry have been used to measure the two orthogonal divergences of the 1.5 pps, 50 MeV electron beam produced at the Accelerator Test Facility at BNL for two different beam tunes. A comparison of the results using OTRI, ODTRI and transport code calculations is presented.
