Advances in laser technology have paved the way for extensive use of laser based particle accelerators for several scientific and technological applications, including compact systems for radiation therapy. The latter has attracted much attention due to its smaller size, lower costs, and radiation safety requirements, compared to conventional particle accelerators. However, diagnostic solutions for the characterization of laser-plasma beams are as limited as essential, owing to the complex mix of energies and emittance of particles present. The Thomson Parabola Spectrometer (TPS) is a promising tool, capable of analyzing various aspects of high-energy ion beams from laser-based accelerators. We present here the first results on the design and realization of a custom TPS developed at INFN-LNS suited to the requirements of a laser-driven beam. The design is performed in the MC simulation toolkit TOPAS which allows modification of TPS parameters according to experimental configurations, as well as properties of the source.
