COMPLEX BALLOON TECHNOLOGY PLATFORM FOR COSMIC RADIATION MEASUREMENTS

The Hungarian experiment

Due to significant spatial and temporal changes in the cosmic radiation field, radiation measurements with advanced dosimetric instruments on-board spacecrafts, aircrafts and balloons are very important.

The objective of the combined TriTel/Pille cosmic radiation and dosimetric measurements is to measure the effects of the cosmic radiation at lower altitudes where measurements with orbiting spacecrafts are not possible due to the strong atmospheric drag. This way it will be also possible to make intercomparison of the measured doses and the first time to use the Linear Energy Transfer (LET) spectra measured by the TriTel 3D silicon detector telescope for corrections during data evaluation of the Pille thermoluminescent dosimeters.

By evaluating the deposited energy spectra recorded by TriTel and the glow curve obtained after the on-ground read-out of the retrieved Pille dosimeters, the LET spectra, the average quality factor of the cosmic radiation as well as the absorbed dose and the dose equivalent can be determined. The results of the two measurements will be intercompared and will be used to make an estimation of the doses that might be expected during launch of manned space flights or even commercial air flights.
