Abstract
The angular coverage extension of the KLOE-2 electromagnetic calorimeter, from a polar angle of 20° down to 10°, will increase the multiphoton detection capability of the experiment enhancing the search reach for rare kaon,ηandprompt 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 (5.5×6×13) cm3prototype for such a detector wa s carried out at the Beam Test Facility of Laboratori Nazionali di Frascati of INFN. We present here the results ofthis test.| File | Dimensione | Formato | |
