Abstract
Dual Readout Calorimetry is a promising new technique for highresolution calorimetry. It is based on simultaneous measurements, in the shower development process, of the scintillation and Cherenkov light (only produced by the electromagnetic shower component). In this way it is possible to measure, event by event, the contribution of the electromagnetic fraction, and to compensate for its fluctuations, that are the main source of degrading the hadronic energy resolution of calorimeters. In order to further improve both the electromagnetic and hadronic resolution, it is possible to reduce both the sampling fluctuations and the quantum fluctuations by using homogeneous, dense crystals. Promising results have been obtained by lead tungstate crystals (PbWO4), doped with small fractions of praseodymium or molybdenum. Results from the 2008 testbeam and perspective for the coming one this year will be shown.
