In this thesis, the different electron optical components necessary to build a linear cavity for multi-pass transmission electron microscopy are analyzed and simulated. Moreover, a prototype of the core component, the gated mirror, was designed and some preliminary experimental testings were carried out to asses its optical properties. Then, an architecture of the complete linear cavity, including the correction of spherical aberration and image rotation was designed, optimized and validated through simulation. Finally, an experimental setup for the characterization of electron optical elements was also designed, implemented and experimentally tested. Such a diagnostics setup is going to be adopted for the verification of the multi-pass components optical properties, performance, and their agreement to the design specifications.
