摘要The angular coverage extension of the KLOE-2 electromagnetic calorimeter, from a polar angle of 20 degrees down to 8 degrees, will increase the multiphoton detection capability of the experiment enhancing the search reach for rare kaon, eta and eta' prompt decay channels. The basic layout of the calorimeter extension consists of two small barrels of LYSO crystals readout with APD photosensors aiming to achieve a timing resolution between 300 and 500 ps for 20 MeV photons. The first test of a (5.5 x 6 x 13)cm(3) prototype for such a detector was carried out in April 2009 at the Beam Test Facility of Laboratori Nazionali di Frascati of INFN with an electron beam from 100 to 500 MeV. In the selected energy range, we measured a light yield of 500-800 p.e ./ Mev, an energy resolution which can be parametrized as 0.05 circle plus 0.01/(E/GeV) circle plus 0.015/ root E/GeV, a position resolution of 2.8 mm and a timing resolution of 200-300 Ps.
