TI  - Compact RF gun setup for Ultrafast Electron Diffraction

AB  - Ultrafast Electron Diffraction (UED) is a powerful tool for probing structural dynamics in solids, liquids and gases with atomic spatio-temporal resolution. Dynamical processes such as phase transitions and chemical reactions are in general irreversible, and therefore interrogation of such processes demands highly charged electron bunches to capture the dynamics with a limited number of shots. Here we present a UED setup headed by a unique pin cathode RF source emitting self-compressing 68 keV electron bunches with a charge up to 100 fC. While synchronization and amplitude instability of the cavity currently limit the accumulation mode temporal resolution to about 500 fs, single shot pulse durations shorter than 300 fs have been recorded. System features and phase space characterizations are outlined, and first results on time resolved laser induced electron plasma generation as well as ultrafast heating of single crystal Gold are presented.
