Integration of the scattering chamber of the NUMEN experiment

Abstract

The NUMEN experiment points to measure Double Charge Exchange reaction (DCE) cross sections with heavy-ion beams interacting with specific isotopes of interest for Neutrinoless Double Beta Decay process (0νββ). To achieve this, NUMEN requires a complete upgrade to MAGNEX spectrometer in INFN-LNS and a high intensity ion beam. This work focuses on the design of a new scattering chamber where the ion beam will interact with the target precisely positioned by an automatic system. The target will be cooled by a custom system based on HOPG and a cryo-cooler. The fist integration of the chamber with all its components has been done at INFN section of Turin to check compliance with the requirements and to study the procedures for the target replacement. Some results of this tests will be presented.
