Abstract

High-precision jet spectroscopy will be increasingly important in future high-energy accelerator experiments, particularly at a Linear e+ e- Collider. DREAM, a novel type of calorimeter, appears to be well suited for this task. The key aspect of this detector is the simultaneous measurement of the scintillation light and the Cherenkov light generated in the shower development process. By comparing these two signals (which are provided by different types of optical fibers), the electromagnetic shower fraction can be measured event by event, both for single hadrons and for jets, and the effects of fluctuations in this fraction can be eliminated. As a result, the DREAM calorimeter has impressive performance characteristics. The application of the DREAM principles in homogeneous calorimeters, which has the potential of providing ultimate calorimeter performance, is also discussed.
