The use of Optical Transition Radiation (OTR) as an on-line diagnostic system for the UCLA Particle Beam Physics Lab electron beam has been investigated. Beam divergence, energy and profile are some of the properties which have been theoretically and experimentally (past works) shown to be analyzable and measurable from OTR patterns. Calculations regarding the survivability of both the beam and the OTR target are made for various beam energies and target materials. It is found that a 20 MeV beam passing through a thin aluminum target will be unperturbed, in terms of energy and angular divergence, and the target will not be destroyed. Finally, the use of an OTR double-foil interferometer, as a more precise diagnostic tool, is presented for future consideration.
