Laser-driven proton acceleration represents an important field of interest for nowadays research. Laser accelerated protons feature interesting characteristics such as beam current, beam charge and bunch duration, that make them potentially a complementary solution to conventional sources and enable several novel applications. Nevertheless, their intrinsic broadband energy spectrum precludes many applications that require more monochromatic proton beams. We report on the design study of a flexible, versatile device for the energy selection of laser-driven proton beams, based on permanent magnets. We concentrate on the energy range from 2 to 50 MeV, i.e the typical energies that can be obtained routinely for ion acceleration using a commercial 250 TW-power laser system. We determine the key technical features of the energy-selector that define the energy selection process in terms of energy bandwidth and transmission efficiency, indicating the best working point based on requirements and technical constraints. As an example of potential applications, we show that laser generated proton beams with a low energy spread can be used in the domain of Cultural Heritage: tailoring the proton beam with an energy selector allows performing an improved material analysis compared to what is currently used in conventional diagnostic techniques.
