ABSTRACT
Due to an expected increase in radiation under Super-LHC (SLHC)
conditions, we propose to substitute the scintillator tiles in the original de-
sign of the CMS hadronic endcap (HE) calorimeter with quartz plates [1].
Various tests proved that quartz is radiation hard [2]. However, the light
produced by quartz comes from Cerenkov process, and it is 100 times less
than scintillation photons. To enhance the light production we treated the
quartz plates with p-Terphenyl, and constructed a 20 layers calorimeter
prototype. Here, we report the test beam results for hadronic and elec-
tromagnetic capabilities of the calorimeter prototype as well as radiation
damage results for P-Terphenyl.
INTRODUCTION
The current design of Large Hadron Collider (LHC) provides 14 TeV
center of mass energy with p-p collisions at a peak luminosity of L = 1035
