Simulation results of a New type of sandwich calorimeter, Double readout Sandwich Calorimeter (DSC) performance

In this study, we propose a novel fully active total absorption calorimeter with enhanced read out capabilities through fine splitting. The proposed calorimeter employs a sandwich structure composed of scintillator glasses and lead glasses, which are subdivided into small tiles. This configuration enables the creation of a finely segmented three-dimensional calorimeter that is compatible with Particle Flow Algorithms (PFA). This article presents a comprehensive description of the calorimeter design and reports performance results obtained through simulations. Notable, calorimeter demonstrates exceptional linearity and energy resolution, closely rivaling that of homogeneous calorimeters. The simulated calorimeter achieves an impressive energy resolution of approximately $ 9\% / \sqrt{E(\textrm{GeV})}$.
