“…For example, the search for new radiation-hard detectors led to the development of silicon carbide (SiC) detectors in the SiCILIA project [51]. The major upgrade of MAGNEX is related to a new focal plane detector (capable of working at rates from a few kHz to several MHz), made of a new gas tracker based on multiple-thick GEM technology, a new SiC-CsI telescope wall for particle identification, and a new array of scintillators, called G-NUMEN [52], for γ-ray measurement in coincidence with MAGNEX. In addition, new electronics, based on the CAEN VX2740 digitizer, and radiation-tolerant isotopically enriched thick targets, with substrates of highly oriented pyrolytic graphite (HOPG), are foreseen [53][54][55][56].…”

“…-to-g.s. transition is not well isolated by using MAGNEX alone and measurements of the γ decay of the first excited states with the G-NUMEN [52] array are needed. In these cases, the beam current should be kept at 10 12 pps in order to limit the average reactions occurring at the target per beam bunch to about 1, thus keeping the best observational limit for DCE g.s.…”

The search for neutrinoless double-beta (0νββ) decay is currently a key topic in physics, due to its possible wide implications for nuclear physics, particle physics, and cosmology. The NUMEN project aims to provide experimental information on the nuclear matrix elements (NMEs) that are involved in the expression of 0νββ decay half-life by measuring the cross section of nuclear double-charge exchange (DCE) reactions. NUMEN has already demonstrated the feasibility of measuring these tiny cross sections for some nuclei of interest for the 0νββ using the superconducting cyclotron (CS) and the MAGNEX spectrometer at the Laboratori Nazionali del Sud (LNS.) Catania, Italy. However, since the DCE cross sections are very small and need to be measured with high sensitivity, the systematic exploration of all nuclei of interest requires major upgrade of the facility. R&D for technological tools has been completed. The realization of new radiation-tolerant detectors capable of sustaining high rates while preserving the requested resolution and sensitivity is underway, as well as the upgrade of the CS to deliver beams of higher intensity. Strategies to carry out DCE cross-section measurements with high-intensity beams were developed in order to achieve the challenging sensitivity requested to provide experimental constraints to 0νββ NMEs.

“…Extensive GEANT4 simulations (Agostinelli et al, 2003;Folger et al, 2004;Allison et al, 2006Allison et al, , 2016Oliveira et al, 2020), based on the BIC (binary intra-nuclear cascade) model of the reaction were performed in order to evaluate this background. The results indicate that cross sections as low as 1 nb, can be measured with uncertainties of the order of 10%, using a beam intensity of the order of 10 12 beam particles per second on typical targets with tenths of mg/cm² surface density in month-long experiments.…”

The goal of NUMEN project is to access experimentally driven information on Nuclear Matrix Elements (NME) involved in the neutrinoless double beta decay (0νββ) by accurate measurements of the cross sections of heavy-ion induced double charge-exchange reactions. In particular, the (18O, 18Ne) and (20Ne, 20O) reactions are adopted as tools for β+β+ and β−β− decays, respectively. The experiments are performed at INFN–Laboratory Nazionali del Sud (LNS) in Catania using the Superconducting Cyclotron to accelerate the beams and the MAGNEX magnetic spectrometer to detect the reaction products. The measured cross sections are very low, limiting the present exploration to few selected isotopes of interest in the context of typically low-yield experimental runs. In order to make feasible a systematic study of all the candidate nuclei, a major upgrade of the LNS facility is foreseen to increase the experimental yield by more than two orders of magnitude. To this purpose, frontier technologies are being developed for both the accelerator and the detection systems. An update description of the NUMEN project is presented here, focusing on recent achievements from the R&D activity.

“…Conversely, LaBr is very fast and can be operated at a high counting rate. In the NUMEN environment, with a high beam current up to 10 12 -10 13 pps, the number of gamma rays produced in the target will be huge: simulations based on experimental cross section data foresee counting rates of the order of 10 5 cps on each detector produced by any kind of nuclear reaction in the target [66]. The challenge is in selecting only those correlated with the ejectile of interest going through MAGNEX, crossing the tracker, reaching the focal plane, and being stopped in the PID.…”

The NUMEN Heavy Ion Multidetector for a Complementary Approach to the Neutrinoless Double Beta Decay

Neutrinos are so far the most elusive known particles, and in the last decades many sophisticated experiments have been set up in order to clarify several questions about their intrinsic nature, in particular their masses, mass hierarchy, intrinsic nature of Majorana or Dirac particles. Evidence of the Neutrinoless Double-Beta Decay (NDBD) would prove that neutrinos are Majorana particles, thus improving the understanding of the universe itself. Besides the search for several large underground experiments for the direct experimental detection of NDBD, the NUMEN experiment proposes the investigation of a nuclear mechanism strongly linked to this decay: the Double Charge Exchange reactions (DCE). As such reactions share with the NDBD the same initial and final nuclear states, they could shed light on the determination of the Nuclear Matrix Elements (NMEs), which play a relevant role in the decay. The physics of DCE is described elsewhere in this issue, while the focus of this paper will be on the challenging experimental apparatus currently under construction in order to fulfil the requirements of the NUMEN experiment. The overall structure of the technological improvement to the cyclotron, along with the newly developed detection systems required for tracking and identifying the reaction products and their final excitation level are described.
