Semi-Digital Hadronic Calorimeter

A key element of future experiments with linear colliders (ILC, CLIC), will be the ability to exploit the particle flow algorithms. They are based on the possibility to follow all the particles produced by e+e- collisions in the various sub-detectors to measure the energy.

Thus, the calorimeters, which until now were used to measure the particle energy will be required to have a tracking capability. In this perspective, we participate with other European and Belgian groups in the development and the construction of a hadron calorimeter with a large granularity as with short-term goal to build a 1m3 prototype.

The calorimeter is based on GRPC detectors used as sensitive medium. Then we participate in data analysis and in test beam particles at CERN. This project will also study the hadronic showers and compare the results
obtained with phenomenological models. The outcome of this comparison should significantly improve our understanding of this phenomenon.
