Abstract

Multi-pass transmission electron microscopy is a novel technique that promises to reduce the required electron dose to the specimen for a desired signal-to-noise ratio by increasing the change to the phase of the electron wave that is imparted by the specimen. In this technique, the electron beam interacts elastically with the specimen multiple times so that the change in the phase accumulates before reaching the detector. Past simulations have predicted an improvement in resolution and sensitivity for a range of applications, and an order-of-magnitude reduction in damage at equivalent resolution. Here, the electron-optical design of a 10 keV multi-pass transmission electron microscope that is currently under construction is examined.
