A novel silicon-on-insulator microdosimeter for estimating the radiobiolgical effectiveness (RBE) of a mixed radiation field is presented. An ion beam induced charge collection study has confirmed the microdosimeter possesses well defined micron sized 3D cylindrical sensitive volumes. An array of these SVs has the capabilitiy of studying the track structure of high energy heavy ions typical of a deep space environment.
