Abstract— Thermionic emission microscope (THEM) is an important aealv,tical research feel for lying Jute electron emission uniformity of a thermionic cathode. The criticality of its design and development stems from the need to characterize the inhomogeneous emission nature of the impregnated cathode surface. In this paper, a design of the lens and the deflection plates is presented for a multi-beam cathode (MBC). To understand the electron optics of THEM with lens and deflection plates system, simulations were carried out using the simulation tools CST Particle Studio software. The present MBC contains 19 protruding buttons-each image is projected onto the screen for study.
