Uniformisation Techniques for Crystals in the ECAL Endcaps

In this paper we present techniques for achieving the desired uniformity of longitudinal light collection in the lead tungstate crystals for the CMS electromagnetic calorimeter endcaps. It is found that shading the chamfered edges of the crystals with a pencil can achieve a reduction in the front no...
