Description
Plastic scintillating fiber trackers read out by Silicon Photomultipliers (SiPMs) are a promising alternative to silicon trackers for space experiments. This technology combines the compactness and low power consumption of SiPMs with the low material budget of plastic scintillators.
NUSES is a satellite mission, currently under construction, aiming to test innovative observational and technological approaches to study cosmic radiation. The Zirè payload on board NUSES will be equipped with three XY fiber tracker modules (FTK), designed for effective tracking of cosmic rays below a few hundred MeV. In addition, the FTK will be able to trigger events from low-energy charged particles, and to contribute to particle identification.
In this contribution the design and the performance of Zirè FTK will be presented, with studies in dedicated beam test campaigns at the CERN PS and SPS accelerator facilities. Finally, the effects of the radiation environment on the SiPM arrays and its impact on the overall performance of the FTK in space will also be discussed.
