Abstract
Due to an expected increase in radiation damage under SuperLHC conditions, we propose to substitute
the scintillator tiles in the original design of the HE Calorimeter with quartz plates. Quartz is shown
to be radiation hard. Using wavelenght shifting fibers, it is possible to collect efficiently the Cerenkov
light generated in quartz plates. This note summarizes the results from various test beams, bench tests,
and Geant4 simulations done on methods of collecting light from quartz plates, as well as radiation
