Thermionic electron gun design and prototyping

Abstract

A prototype thermionic electron gun is designed and produced at Bogazici University’s KAHVE Laboratory to gain experience on electron sources towards industrial electron beam applications. The electron gun includes a thoriated tungsten filament, a Wehnelt cup, an anode, a Faraday cup and a solenoid. Electron gun simulations were performed by using the IBSimu program. The produced electron gun is operating at 20 kV and produces beam currents up to 3 mA. This paper reports the experimental results and encountered problems during the construction of the thermionic electron gun.
