We gratefully acknowledge the contributions of Tracy McAskill, Vladimir Nagaslaev, Alan Sill, Veronica Stelmakh, Yunyong Wang, Erika Washington and Kim Zinsmeyer to the construction of the DREAM detector. We thank CERN for making particle beams of excellent quality available. Our beam tests would not have been possible without the help we received from Claude Ferrari and Maurice Haguenauer. We thank K. Kuroda for loaning us the fiber hodoscopes, and A. Gorin and I. Manouilov for their assistance with the data acquisition system. This study was carried out with financial support of the United States Department of Energy, under contract DE-FG02-95ER40938, and the Advanced Research Program of the State of Texas.

N2 - Results are presented of detailed measurements of high-energy electromagnetic shower profiles measured in a copper-based fiber calorimeter. The calorimeter was equipped with a mixture of scintillating fibers and undoped (quartz or clear plastic) fibers. The latter measured Cherenkov light generated in the shower development process, whereas the scintillating fibers measured the energy deposit profile. Both lateral and longitudinal profiles were measured for electrons in the energy range 8-200 GeV. The scintillator and Cherenkov profiles exhibit some very striking differences, which are discussed and compared with results of Monte Carlo simulations.
