Abstract
Multi-pass optical and electron microscopes outperform standard single-pass instruments in dose-limited regimes and have been shown to be quantum optimal. We report on recent progress towards demonstrating multi-pass transmission electron microscopy with a focus on the electron gun and monochromator system. Prompt electron emission from a Schottky emitter is laser-triggered with nanosecond optical pulses, and a single-photon emission process can be used to generate high current pulses with narrow intrinsic energy spreads. These pulse properties could be useful for nanosecond time-resolved and potentially single-shot microscopy experiments and are well-suited for use in a multi-pass transmission electron microscope.
