Laser-based ion acceleration: a new technique for innovative radiobiological studies and future medical applications
Giorno 6 febbraio 2020, con inizio alle ore 15:00, presso l'Aula L del DFA, la Dott.ssa Giuliana Milluzzo (Center for Plasma Physics, School of Mathematics and Physics, Queen's University Belfast, UK) terrà un seminario dal titolo Laser-based ion acceleration: a new technique for innovative radiobiological studies and future medical applications.
Il seminario rientra nel ciclo Highlights in frontier physics del Corso di PhD in Physics.
Tutti gli interessati sono invitati a partecipare.
Abstract. Proton and ion beams accelerated by high-power lasers are typically characterized by a broad energy spectrum and divergence an high flux per shot (up to 1012 p/bunch) delivered in a very short time and an extremely high dose-rate exceeding 10^9 Gy/s. All these peculiarities, if well controlled, are very attractive in fundamental nuclear as well as in the applied physics providing an alternative approach for beam delivery to the large and expensive infrastructure currently required in conventional acceleration.
In particular, investigations are still in progress aimed at improving the proton acceleration in terms of energy, flux and divergence through the development of innovative structured targets and of specific compact transport beam lines needed to assure the quality and the suitability of these beams for applications such as the medical one.
Moreover, the study of the radiobiological response of cells to protons delivered with a dose-rate higher than the one conventionally used is gaining a growing interest due to the discovery of the so-called FLASH effect. An extensive investigation of the radiobiological effectiveness of laser driven ion pulses also offers the opportunity of accessing yet untested regimes of radiobiology where the dose is delivered to biological samples at a even higher dose rates exceeding by many orders of magnitude what normally possible with conventional RF accelerators.
An overview of the current status on laser-based ion acceleration and their application will be reported together with recent experimental results.
