Proton and iron ion observations from a solid-state microdosimeter

Journal Article


Abstract


  • The tissue equivalent proportional counter (TEPC) that utilises a gas cavity has been the standard to obtain microdosimetric

    observations. An alternative is the solid-state microdosimeter that replaces the gas with a solid-state detector with microscopic

    sensitive volumes. Here, we describe the development of two versions of a personal solid-state microdosimeter for space

    exploration applications and give test results for iron and proton beams with comparisons to TEPC measurements and

    Geant4 radiation transport code simulations. In addition, we describe and provide test results of an optical technique to carry

    out an end-to-end system test and calibration of a silicon solid-state microdosimeter. This technique eliminates the need for an

    ionising radiation source with its attendant issues on use and transportation and provides an advantage over the TEPC.
