Title: Highly Granular Calorimeters: Technologies and Results,
Abstract: The CALICE collaboration is developing highly granular calorimeters for
experiments at a future lepton collider primarily to establish technologies for
particle flow event reconstruction. These technologies also find applications
elsewhere, such as detector upgrades for the LHC. Meanwhile, the large data
sets collected in an extensive series of beam tests have enabled detailed
studies of the properties of hadronic showers in calorimeter systems, resulting
in improved simulation models and development of sophisticated reconstruction
techniques. In this proceeding, highlights are included from studies of the
structure of hadronic showers and results on reconstruction techniques for
imaging calorimetry. In addition, current R&D activities within CALICE are
summarized, focusing on technological prototypes that address challenges from
full detector system integration and production techniques amenable to mass
production for electromagnetic and hadronic calorimeters based on silicon,
scintillator, and gas techniques.
