Simultaneous detection of the Cherenkov light and scintillation light produced in hadron showers makes it possible to measure the electromagnetic shower fraction event by event and thus eliminate the effects of fluctuations in this fraction, which limit the precision with which hadrons and jets can be detected in calorimeters. In the RD52 (DREAM) project, the possibilities of this dual-readout calorimetry are investigated and optimized. In this talk, the latest results of this project are presented. These results concern the first tests of the partially completed full-scale SuperDREAM fiber calorimeter, which were recently carried out at CERN.
