摘要：

At the core of the AGILE scientific instrument, designed to operate on a satellite, there is the Gamma Ray Imaging Detector (GRID) consisting of a Silicon Tracker (ST), a Cesium Iodide Mini-Calorimeter and an Anti-Coincidence system of plastic scintillator bars. The ST needs an on-ground calibration with a gamma-ray beam to validate the simulation used to calculate the energy response function and the effective area versus the energy and the direction of the gamma rays. A tagged gamma-ray beam line was designed at the Beam Test Facility (BTF) of the INFN Laboratori Nazionali of Frascati (LNF), based on an electron beam generating gamma-rays through bremsstrahlung in a position-sensitive target. The gamma-ray energy is deduced by difference with the post-bremsstrahlung electron energy [1,2]. The electron energy is measured by a spectrometer consisting of a dipole magnet and an array of position sensitive silicon strip detectors, the Photon Tagging System (PTS). The use of the combined BTF-FTS system as tagged photon beam requires understanding the efficiency of gamma-ray tagging, the probability of fake tagging, the energy resolution andthe relation of the PTS hit position versus the gamma-ray energy. This paper describes this study comparing data taken during the AGILE calibration occurred in 2005 with simulation. (C) 2012 Elsevier B.V. All rights reserved.
