A Center-holed Faraday Cup Monitor for an Electron Microbeam Single Cell-irradiator

An electron microbeam cell irradiator is used in radiation biology by using an in vitro cell irradiation. The Korea Institute of Radiological and Medical Sciences (KIRAMS) has operated Such a system since 2002, when it performed its first cell irradiation experiment. But there is no appropriate real time electron beam monitoring apparatus for an electron beam. In this study, we designed a new center-holed Faraday cup monitoring system and evaluated its operation characteristics.
