Abstract
The angular coverage extension of the KLOE-2 electromagnetic calorimeter, from a polar angle of 20° down to 8°, will increase the multi photon detection capability of the experiment enhancing the search reach for rare kaon, η and η' prompt decay channels. The basic layout of the calorimeter extension consists of two small barrels of L YSO 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) cm3 prototype for such a detector was carried out at the Beam Test Facility of Laboratori Nazionali di Frascati of INFN and we present here the first results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
