In this research, a low-energy secondary emission electron gun using wire ion plasma source was developed. The characteristics of secondary electron beam were investigated in order to achieve main objective, which is to realize the sterilization using pulsed electron beams. The electron dose per unit time was also observed by film-type dosimeter, and it was confirmed to increase at the higher repetition rate. The sterilization experiments were conducted using bacteria called Bacilus pumilus which is the biological indicator of radiation sterilization. It is found that the inactivation effect is intensified by increasing the repetition rate of the electron beam irradiation. Furthermore, morphological damage to the bacteria is observed by Field Emission-Scanning Electron Microscope. It is observed that the damage are caused by radial effects that it is attributed to electron beam irradiation.
