FiberGLAST is one of two main-instrument concepts being studied for NASA's Gamma-ray Large Area Space Telescope (GLAST) mission. It uses a large volume ( ~ 3 m3) of scintillating fiber detectors combined with passive conversion material to image gamma-ray induced showers in the energy range ~ 10 MeV to 300 GeV. In addition to meeting the formidable GLAST science performance requirements, FiberGLAST offers exceptionally large effective detection area ( > 1 m2) over a wide field-of-view ( > 70 deg HWHM). These characteristics make it well-suited to perform a sensitive all-sky survey and to monitor a large population of variable sources, such as active galactic nuclei and gamma-ray bursts. We present an overview of the FiberGLAST instrument concept design and report results on hardware development, accelerator beam test results, and instrument performance simulations.
