Description
The Alpha Magnetic Spectrometer(AMS-02) is a particle detector that operates on the International Space Station(ISS), which aims to search for antimatter, and dark matter while performing precision measurements of cosmic rays composition and flux. To improve cosmic ray acceptance and heavy ions resolution, a new layer(L0) of silicon strip tracker will be installed on top of AMS-02. Multiple test beam activities were performed to study the L0 silicon tracker performance. A telescope system based on silicon microstrip detectors is developed for the beam test studies.
This talk will introduce the design of this telescope system. This telescope consists of multiple single-SSD modules with a readout electronics system similar to that of the L0 detector. A hybrid machine learning algorithm was introduced to address the challenges of charge reconstruction with multi-strips. This telescope's performance for heavy ion particle identification and position measurement will be presented.
