“…Figure 5 reports the tangent of the angle with respect to the beam direction of fragments, separated according to their charge for a 400 MeV/u 16 O beam on a C 2 H 4 target. The reported tracks are the ones well reconstructed in the second section of the apparatus, while the charge has been distinguished by employing the ionization sensitivity of the second section of the apparatus (for Z ≤ 2) and further analysis procedures [6]. In particular, the sensitivity of the apparatus is not suited for heavier fragments (for Z ≥ 4), whose discrimination is not the purpose of this detector.…”

The main goals of the FragmentatiOn Of Target experiment are the measurements of double-differential fragmentation cross-sections of light particles (Z < 10) in the energy range between 100-800 MeV/u, which is of interest for hadron therapy and space radioprotection applications. The results will fill the gap in experimental data in this range, which is important for improving the treatment planning systems in particle therapy and for enhancing the reliability of risk-assessment models for space radioprotection. Two different setups were designed for this scope, and data have already been taken in several campaigns. In this paper, an overview of the apparatus is described, focusing on the preliminary results of crosssection measurements obtained with a 16 O beam at the GSI facility. topics: FOOT (FragmentatiOn Of Target), nuclear fragmentations, cross sections measurements

“…Two complementary setups have been developed: one based on nuclear emulsion films, mainly dedicated to the characterization of fragments with 𝑍 ≤ 3, and one made of electronic devices, focused on heavier fragments (2 ≤ 𝑍 ≤ 8). The Emulsion Spectrometer will not be discussed since it is not the subject of this work, but detailed information can be found in [5].…”

FOOT (FragmentatiOn Of Target) is an applied nuclear physics experiment with the aim of performing high precision cross section measurements for fragmentation reactions of interest in hadrontherapy and radiation protection in space. The physics program of the experiment foresees a set of measurements with light ion beams, such as C and O, in the energy range of 100–800 MeV/u interacting with tissue-like and shielding material targets. The setup was initially conceived for the detection of charged fragments and, in 2021, the Collaboration started the study of possible solutions for neutron detection. Two detection systems have been proposed: one based on BC-501A liquid scintillators with neutron/γ discrimination capabilities and a system based on BGO crystals operated in phoswich mode. In 2022, a dedicated data acquisition campaign was carried out at the n_TOF facility at CERN to evaluate the capabilities of the two systems. First, the neutron/γ discrimination efficiency of the BC-501A system was studied using radioactive sources. Then, the two systems were placed in the n_TOF experimental area to study their neutron detection efficiency under a well characterized neutron beam. In this work, the first preliminary results concerning the characterization of the two possible neutron detectors of FOOT are presented.

“…The nuclear emulsion spectrometer, composed of alternating layers of nuclear emulsion films and passive materials, was designed for the reconstruction of interaction vertices and the measurement of the charge and momentum of secondary particles. The procedure to identify the charge of secondary fragments generated by the interaction of a 16 O (200 MeV/n) beam on a C 2 H 4 target using the emulsion detector was reported in previous work [11]. This analysis is based on an established technique that involves controlled fading of nuclear emulsion films using different thermal treatments [12][13][14][15] that extend their dynamic range response, allowing the identification of particles with different charges and specific ionization.…”

Introduction: Charged Particle Therapy plays a key role in the treatment of deep-seated tumours, because of the advantageous energy deposition culminating in the Bragg peak. However, knowledge of the dose delivered in the entrance channel is limited by the lack of data on the beam and fragmentation of the target.Methods: The FOOT experiment has been designed to measure the cross sections of the nuclear fragmentation of projectile and target with two different detectors: an electronic setup for the identification of Z ≥ 3 fragments and a nuclear emulsion spectrometer for Z ≤ 3 fragments. In this paper, we analyze the data taken by exposing four nuclear emulsion spectrometers, with C and C2H4 targets, to 200 MeV/n and 400 MeV/n oxygen beams at GSI Helmholtzzentrum für Schwerionenforschung (Darmstadt, Germany), and we report the charge identification of produced fragments based on the controlled fading induced on nuclear emulsion films.Results: The goal of identifying fragments as heavy as lithium has been achieved.Discussion: The results will contribute to a better understanding of the nuclear fragmentation process in charged particle therapy and have implications for refining treatment planning in the presence of deep-seated tumors.
