Beam tests of a 3-D position sensitive scintillation detector
An array of 30 position sensitive scintillator bars has been tested in a gamma-ray beam from I.N.S.T.N. Van de Graff facility at the Centre d'Etudes Nucleaires, Saclay, France. The gamma-ray energies ranged from 6 MeV to 17 MeV. The bars are similar to those proposed for use in the GRASP gamma-ray telescope satellite imaging plane. They are manufactured from CsI(T1) covered with a highly reflective diffusive wrapping, and are read out using large area PIN photodiodes. Each bar measures 15.0 cm by 1.3 cm by 1.3 cm. The beam test unit was comprised of 30 bars stacked in a 5 by 6 array. The photodiodes were optically coupled to the end face of each bar and were connected to a processing chain comprised of a low noise preamplifier, a high gain shaping amplifier, and a digitisation and data collection system. Several experiments were performed with the unit to assess the spectral response, position resolution, and background rejection capabilities of the complete detector. The test procedure is explained and some results are presented.
