Abstract: This paper reviews the development of a teaching laboratory on electron optics. The experimental measurement is carried out on the cathode ray tube of a single-trace oscilloscope. The results from the simulation software Simion and Comsol are very helpful for understanding the electron traces in the lens system.

Key words: electron optics, cathode ray tube (CRT), simulation sostware
