Pictured above is a photograph of the entire mechanical structure of the McMaster NEUDOSE satellite. The 10cm x 10cm x 30cm satellite is about the same size as a loaf of bread. Mounted inside the satellite is the Tissue Equivalent Proportional Counter (TEPC), a major component of the radiation detection system. The panels protruding from the aluminum body contain the solar panels that will convert solar energy to electrical energy for the satellite.
