Introduction
· Super-LHC is planned to run at luminosity of 1035 cm-2s-1. Some part of
existing CMS HE calorimeter scintillators are going to get ~25 MRad
radiation. University of Iowa, Mississippi, and Fairfield University propose to
replace them with quartz plates.
· Good : Quartz is radiation hard.
· Bad : We have to collect cerenkov photons. Very little light !! At fixed angle.
· Strategy: Go deep in UV to collect cerenkov photons.
· We did R&D studies on
­ WLS fiber geometry
