| Popis: | 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. |
