Abstract

A dosimeter for space applications is presented. It is based on the ionization damage affecting the TMP36 sensors when they are exposed to external radiation, which produces an increase of their output voltages. This work explains the configuration, sensing mechanism and working modes of this device and reports the results obtained in a gamma radiation test carried out in March 2012. The test results allow us to select the mode of operation that provides the highest response to the TID, as well as the most sensitive devices. The highest sensitivity is above 100 μV/rad. This dosimeter is part of The Two Towers radiation monitor that will fly on board of the SEOSAT-INGENIO satellite.
