Description
The Zirè instrument onboard the NUSES space mission is designed to study low-energy electrons, protons and light nuclei from a few MeV up to several hundred MeV. This enables study of space weather phenomena and potential Magnetosphere-Ionosphere-Lithosphere Couplings signatures. Zirè consists of a Fiber Tracker, a Plastic Scintillator Tower, an Anti-Coincidence System, and a GAGG-based calorimeter, with a full SiPM readout. The high light-yield calorimeter also allows gamma-ray detection in the 0.1-30 MeV range, providing sensitivity to transient events such as gamma ray bursts, solar flares, and the MeV gap in the gamma ray spectrum. The mission is scheduled for launch in 2027. We report the activities carried out up to the integration of the Engineering Qualification Model.
