Development of a MAPS-Based Silicon Tracker for the Hyperon–Nucleon Spectrometer at HIAF

HIAF’s Hyperon–Nucleon Spectrometer targets hyperons, hypernuclei and nucleon polarization at 3–32 GeV. Its barrel-and-endcap tracker uses MIC6 monolithic pixel sensors and lightweight construction for precise secondary vertices with minimal scattering. The presentation covers resolution and material targets, Monte Carlo optimization of geometry and supports, and production facilities for module assembly and testing.
