Abstract. MARS (Modular Apparatus for nuclear Reactions Spectroscopy) consists of a compact, portable and, therefore, versatile spectrometer for measuring nuclear reactions and carrying out energy spectroscopy. MARS, as a system, is com posed by 3 sub-systems: detection, electronic, and data acquisition. The de tection sub-system is based on 16 silicon (Si) SBD (Surface Barrier Detectors) from ORTEC, being 8 detectors 15 µm thick and 8 detectors 500 µm thick (nominal values). Thus, MARS allows for coupling 8 Si telescopes. Detectors are connected to an electronic system based exclusively on desktop and VME modules from CAEN (Costruzioni Apparecchiature Elettroniche Nucleari) SpA company. A PC handles the data acquisition by means of CoMPASS (CAEN Multi-PArameter Spectroscopy Software). It manages parameters, builds plots, and saves the relevant energy and time spectra. MARS has been developed in collaboration with CAEN SpA (electronics developer and manufacturer) and ATI Sistemas SL (CAEN SpA commercial representative in Spain). The multi channel feature of MARS allows for measuring angular and energy distributions of charged particles outgoing from a nuclear reaction. This work aims to present MARS as a spectrometer and its characterization. It includes a measurement of the 6Li+12C nuclear reaction, carried out at the 3MV tandem of the CNA (National Accelerator Centre), in Seville, Spain.
