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})}$.

A relation between track length and deposited energy in a homogeneous calorimeter by Geant4 simulation at high energy

We performed a Geant4 simulation study on showers generated by electrons and hadrons in a large homogeneous calorimeter. We found that the energy deposit can be expressed as a linear function of the track length. The line does not pass through the origin, and the energy deposit at the intercept is proportional to the incident energy. Moreover, for both electrons and hadrons, the slope of the line is independent of the incident energy. The energy resolution of the calorimeter can be expressed in terms of the distribution around the correlation line, which we found to be very good at about $ 19\% / \sqrt{E(\rm{GeV})}$ for pions.
