An Overview of the Scintillating Fiber Telescope for Energetic Radiation (SIFTER)
Abstract
The Scintillating Fiber Telescope for Energetic Radiation (SIFTER) is a large-area instrument concept for NASA's Gamma Ray Large Area Space Telescope (GLAST) program. The instrument is designed for high-energy (E > 10 MeV) gamma-ray astronomy, and uses plastic scintillating fibers to combine a photon pair tracking telescope and a calorimeter into one instrument module. The design offers a large effective area, and good angular resolution. A small prototype of the detector, consisting of eight plastic fiber layers, each with a 2 times 2 cm active area, has been tested with high-energy photons (~0.3-4 GeV) at a particle accelerator facility. We present an overview of the SIFTER design and detector capabilities, and report on preliminary results from the accelerator beam test.
