| Zusammenfassung | The object of investigation in nanodosimetry is the physical characteristics of the microscopic structure of ionising particle tracks, i.e. the sequence of the interaction types and interaction sites of a primary particle and all its secondaries, which reflects the stochastic nature of the radiation interaction. In view of the upcoming radiation therapy with carbon ions, the ionisation structure of the carbon ion track is of particular interest. Recently, an approved European Joint Research Project called BioQuaRT [1], acronym of Biologically weighted quantities in radiotherapy, aims to lay the foundations for a new concept of radiation quality that is based on measurable physical characteristics of ionising particle track structure. BioQuaRT encompasses eight European research institutes: PTB Germany, ENEA Italy, IRSN France, IST/ITN Portugal, NBCJ Poland, NPL United Kingdom and PoliMi Italy. The project will develop measurement and simulation techniques for multi-scale characterisation of particle track structure from about 2 nm to about 10 μm (i.e. from DNA scale up to cell nucleus) for investigating at the cellular level how these track structure characteristics correlate with the biological effects of radiation. The sought new concept of radiation quality would impact radiotherapy by enabling improved treatment planning and the development of beam monitors and dosimeters suitable to measure the radiation quality via the characteristics of the ion track structure. Concerning the nanodosimetry, to date, three types of nanodosimeter have been developed that are capable of measuring track structure of ionising particles in a gas target equivalent to a nanometric site in condensed matter. Two of these three nanodosimeters are involved in the ILITS project, namely the INFN STARTRACK Counter and the PTB Ion Counter. ILITS is an acronym of Investigation of Light-Ion Track Structure. The aim of the project is to contribute to the more fundamental investigations of BioQuaRT on the correlation between characteristics of track structure for different target sizes by carrying out measurements using the PTB Ion Counter and the INFN STARTRACK detector for the same particles and energies. Measurements will be focused first of all on Carbon beam, because of the upcoming novel techniques of radiation therapy and, secondly, on other light ions. ILITS will last three years as the parent project BioQuaRT and will end by May 2015 |
