Abstract

ADAMO is a magnetic spectrometer that has been developed to allow a precise measurement of the spectra of the main cosmic-ray charged components at ground level. The detector is composed of two main subsystems. The first is a permanent magnet with a cavity where the magnetic field is around 0.4 T. The second is a tracking system made of five double sided silicon micro-strip detecting units with spatial resolutions of 3 mu m and 11 mu m along two orthogonal directions (related to the two sides of the silicon sensors and conventionally referred to as "x" view and "y" view in this work). The whole spectrometer dimensions are (25 x 35 x 25) cm(3); anyway it allows the measurement of charged particles in the wide range of momenta between about 100 MeV/c and 100 GeV/c. During 2003 and 2004 the detector has been modified with respect to its original structure. The acceptance has been increased to allow the study of the rare components of cosmic rays at ground. At present, the magnetic cavity is (60 x 140 x 210) mm(3). A new trigger system has been realized an it is under development to work as a TOF system, the first step to allow particle discrimination at low momentum. During 2004 a first set of data was taken at different zenith angles to test the functionality and the performances of the detector. In this work the apparatus and some analysis of these data are presented.
