Applications of Radio Frequency Resonant Cavities in Ultrafast Electron Microscopy

Radio frequency resonant cavities are becoming important components in the emerging field of Ultrafast Electron Microscopy, which aspires to bring Dynamic Transmission Electron Microscopy into the realm of sub-nanometer spatial resolution combined with sub-picosecond time resolution. To accomplish this goal, the time-varying electromagnetic fields of resonant cavities can be utilized for temporal focusing of laser-driven ultrafast electron pulses to be used for imaging. In this thesis I present the design and construction of a laser-synchronized dielectric-filled radio frequency resonant cavity used for temporal focusing. I also present the theoretical groundwork, design, and construction of a second resonant cavity for the purposes of phase synchronization and direct electron pulse duration measurement.
