Microdosimetry with solid-state detectors at MedAustron

Supervisor: Albert Hirtl

Proton and ion-beam therapy have become established methods for cancer treatment in a growing number of facilities around the globe and have been available in Austria at MedAustron since 2016. Determining the dose to the irradiated tissue is an integral part of every treatment. Currently, the dose delivered during the irradiation process is mostly specified as energy deposited per unit mass. This is a macroscopic quantity and does not provide information on the interactions at the level of cellular structures, where energy deposition is heterogeneous, such as around the particle tracks of ion beams. Therefore, research to characterise the energy deposition at the microscopic level is pursued at MedAustron using microdosimeters. These are radiation detectors in which the dimensions of the sensitive volume are of the order of a few micrometers to simulate cell nuclei. Silicon and diamond microdosimeters as well as gas-filled tissue equivalent proportional counters have been in use regularly and are studied in an ongoing joint research project at MedAustron. 

The selected candidate will participate in ongoing research with experts from MedAustron and will investigate new methods and detectors for their application in microdosimetry with support from all involved partners.
