CALICE highly granular calorimeters: imaging properties for hadronic shower analysis

The CALICE collaboration pioneered the new trend in calorimetry—highly granular devices for high energy and particle physics applications. During the last fifteen years, several highly granular electromagnetic and hadron calorimeters based on different technologies were constructed and successfully tested. The technologies comprise optical readout, signal collection with semi-conducting devices and gaseous detectors. All current CALICE prototypes address technological aspects such as embedded electronics. Dedicated tools are developed for the analysis of test beam data collected with the standalone and combined setups of both physics and technological prototypes of highly granular calorimeters. The tools are described, which help to improve the precision of hadronic shower analysis including the implementation of a calorimeter-based particle identification.
