CMS HCAL Detector Upgrade Studies for SLHC Conditions

Super Large Hadron Collider (SLHC) will have reduced bunch spacing, increased interactions and crossings compared to LHC. These changes will increase the integrated luminosity to 1000 fb$^{-1}$/yr. Under such high radiation conditions the scintillators used for hadron calorimeter (HCAL) of the CMS detector will not survive. As a solution to this problem we propose to use quartz plates along with waveshifting fibers. In this talk we summarize the tests performed and methods developed to increase the efficiency of the quartz plates as well as radiation damage tests done by University of Iowa CMS group.
