  Analysis of the CMS data and the simulation prediction based on these results
indicate that the performance of the current scintillators in the CMS Hadron
Endcap Calorimeter (HE) tiles will degrade dramatically in the High Luminosity
LHC (HL-LHC) era. In order to continue the physics program in this region, the
HE tiles will need to be replaced. The new tiles should have
comparable/improved performance, be radiation hard, reliable and robust.
