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