title = "GALI - A GAmma-ray burst Localizing Instrument: Results from Full-Size Engineering Model",
abstract = "We present a full-size engineering model of GALI - The GAmma-ray burst Localizing Instrument, composed of 362 CsI(Tl) small cubic scintillators, distributed within a small volume of ∼ 2l, and read out by silicon photomultipliers. GALI can provide directional information about GRBs with high angular accuracy from angle-dependent mutual obstruction between its scintillators. Here, we demonstrate GALI's laboratory experiments with an 241Am source, which achieved directional reconstruction of <3◦ accuracy, in agreement with our Monte-Carlo simulations. GALI has a wide field view of the unobstructed sky. With its current cubic configuration, GALI's effective areavaries between 97 cm 2 (face on) and 138 cm 2 (from the corners at 45 ◦), which is verified in the current experiment.",
