High brightness ultrashort electron beams have been produced at the UCLA Pegasus photoinjector lab for use in time-resolved electron diffraction applications. Beams have been generated with high enough brightness to obtain single shot diffraction patterns of thin solid targets. These beams contain a few pC at 3.5 MeV in a 200 fs pulse. Pump-probe experiments on thin metal foils have already shown promising results on picosecond time scales*. Current research focuses on materials with processes that are observable on the sub-100 fs scale. To overcome rf jitter and synchronization problems, electro-optic sampling is used as a single shot time-of-arrival diagnostic** to help reconstruct the melting "movie." *P. Musumeci, et al., Rev.
