Abstract
The KLOE-2 detector has been successfully rolled in inside the new interaction region of the DAΦNE machine, which is still in its commissioning phase. Construction of detector upgrades is in progress to provide larger acceptance both for charged particles and photons. The CCALT calorimeters will be placed in front of the inner quadrupoles, inside the apparatus, thus increasing the acceptance for prompt decay channels. They consist of two barrels of LYSO crystals, read-out with large area SiPM. This choice provides high efficiency for low energy photons and good timing performances, needed to reject machine background events. Tests of a calorimeter prototype were carried out both with electron and photon beams, showing high light yield and good timing capabilities. The construction of the CCALT detector is in progress and will be completed in few months, in time for installing it over the new interaction region.
