Abstract

In recent years a new concept of particle acceleration has gained interest. It is based on high power, short pulse lasers interacting with thin metal foils. In the interaction process the target is suddenly ionized and the charge separation, originating from different phenomena, can efficiently accelerate ions and in particular protons from the target impurities. The peculiar characteristics of laser-driven beams are extremely promising and, moreover, the laser-based accelerators are expected to be more compact and less expensive than conventional machines. Recently, a great interest has been devoted to the multidisciplinary applications of this new kind of beams, in particular to the development of a new concept of hadrontherapy centers. In order to reach this goal a new project, maned ELIMED (MEDical and multidisciplinary application at ELI-Beamlines), has been launched between FZU (Fizikalny Ustav, CZ) and LNS-INFN (Laboratori Nazionali del Sud - Istituto Nazionale di Fisica Nucleare, IT). Several European research institutes with expertise in different fields are now involved in the project. In the development of a dedicated beam transport line, beam diagnostic is a crucial task since it allows to control and select the different beam components in terms of energy and q=m and, also, to have information on the laser-matter interaction. An high energy resolution Thomson Parabola Spectrometer (TPS) has been already realized and successfully tested at PALS in 2012. Recently, the TPS has been upgraded and tested in other experimental runs allowing to obtain better results.
