Abstract
The upgrade of the DA Phi NE machine layout requires a modification of the size and position of the inner focusing quadrupoles of KLOE-2 thus asking for the realization of two new calorimeters covering the quadrupoles area. To improve the reconstruction of K(L) -> 2 pi(0) events with photons hitting the quadrupoles a calorimeter with high efficiency to low energy photons (20-300 MeV), time resolution of less than 1 ns and space resolution of few cm, is needed. To match these requirements, we are designing a tile calorimeter. QCALT, where each single tile is readout by SiPM for a total granularity of 2400 channels. We show first tests of the different calorimeter components. (C) 2009 Elsevier B.V. All rights reserved.| File | Dimensione | Formato | |
