Abstract
The realization of a new focal plane detector for the MAGNEX large acceptance magnetic spectrometer (installed at the INFN-LNS laboratory) is one of the current focuses of the R&D activities within the NUMEN project. The project aims to provide data-driven evaluation of the neutrinoless double beta (0νββ)-decay nuclear matrix elements by measuring the extremely low Heavy-Ion induced Double Charge Exchange reaction cross sections (tens of nb). In this scenario, the ongoing upgrade of the INFN-LNS infrastructure toward unprecedented high fluencies of ions (1013 ions/cm2 integrated in the 10 years prospected duration of the project) is of fundamental importance, encouraging the application of innovative technologies for the new detection system. The new focal plane detector consists of a low pressure gas tracker based on micropattern gas detector (namely multiple thick gas electron multipliers) and an array of SiC-CsI(Tl) telescopes for particle identification (PID-Wall). A first characterization of the tracker prototype coupled with a single SiC detector has been performed using 241Am radioactive α sources. This contribution will introduce the detector and its working principle, reporting the main results obtained during the tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
