“…It allows to implement the particle transport physics and the creation of secondary particles, covering a wide range of energies (from eV to TeV). Geant4 allows to simulate PIXE 63 reliably, as validated by several recent works [64][65][66] . Our Monte Carlo simulations take into account protons, electrons, positrons, and photons.…”

Ion beam analysis techniques are among the most powerful tools for advanced materials characterization. Despite their growing relevance in a widening number of fields, most ion beam analysis facilities still rely on the oldest accelerator technologies, with severe limitations in terms of portability and flexibility. In this work we thoroughly address the potential of superintense laser-driven proton sources for this application. We develop a complete analytical and numerical framework suitable to describe laser-driven ion beam analysis, exemplifying the approach for Proton Induced X-ray/Gamma-ray emission, a technique of widespread interest. This allows us to propose a realistic design for a compact, versatile ion beam analysis facility based on this novel concept. These results can pave the way for ground-breaking developments in the field of hadron-based advanced materials characterization.

“…The present work is a continuation of the evaluation of the updated Geant4 fluorescence simulation capabilities, that we recently published in Francis et al [4] for a selection of complex samples. Here, we propose to investigate the performance of the version 10.1Beta public release of the Geant4 toolkit for the simulation of fluorescence spectra induced by low energy (1.5 MeV) protons on a selection of thin reference targets made of gold, platinum, gadolinium fluoride and iron.…”

“…These models are accurate for energies between 250–100 GeV and can be applied down to 100 eV with a reduced accuracy [ 66 ]. Apart from that, fluorescence, Auger electrons and atomic de-excitation initiated by other electromagnetic processes have been explicitly included for energies over 100 eV [ 67 ]. In the case of muons, we have only considered electromagnetic processes, while for neutron-induced recoils, we have used the NeutronHP model.…”

TREX-DM: a low-background Micromegas-based TPC for low-mass WIMP detection

If Dark Matter is made of Weakly Interacting Massive Particles (WIMPs) with masses below GeV, the corresponding nuclear recoils in mainstream WIMP experiments are of energies too close, or below, the experimental threshold. Gas Time Projection Chambers (TPCs) can be operated with a variety of target elements, offer good tracking capabilities and, on account of the amplification in gas, very low thresholds are achievable. Recent advances in electronics and in novel radiopure TPC readouts, especially micro-mesh gas structure (Micromegas), are improving the scalability and low-background prospects of gaseous TPCs. Here we present TREX-DM, a prototype to test the concept of a Micromegas-based TPC to search for low-mass WIMPs. The detector is designed to host an active mass of kg of Ar at 10 bar, or alternatively kg of Ne at 10 bar, with an energy threshold below 0.4 keVee, and is fully built with radiopure materials. We will describe the detector in detail, the results from the commissioning phase on surface, as well as a preliminary background model. The anticipated sensitivity of this technique may go beyond current experimental limits for WIMPs of masses of 2–8 GeV.
