Description
AMS-02 is a Cosmic Rays detector installed on the International Space Station in May 2011. The core of the instrument is a spectrometer made of a permanent magnet and 9 layers of silicon tracker aims to measures rigidity (momentum over charge) of the particles and the sign of their charge. In addition, it measures the specific energy loss of charged particles to determine the charge magnitude.
For the end of 2024, AMS-02 will be upgraded by adding a plane of silicon tracker (called "L0") on top of the detector, increasing its acceptance by a factor 3 for the major part of the measurements. A L0 prototype has been exposed to ion beams at CERN. In this contribution, a preliminary study of L0 response to nuclei from helium up to the nitrogen will be presented. The applied procedure that allows to extract the charge resolution from the raw collected signal by silicon sensors will be shown. The obtained results will be compared with the actual AMS-02 charge reconstruction capabilities.
