Uniformisation Techniques for Crystals in the ECAL Endcaps / Britton, David ; Ryan, Matthew John ; Qu, Xiangdong ; Häfliger, P
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 non-uniformity of approximately 0.1%/Xo. [...]

Uniformisation of Lead Tungstate Crystals for the CMS Electromagnetic Calorimeter Endcaps / Britton, D I (Imperial Coll., London) ; Ryan, M (Imperial Coll., London) ; Qu, X (Imperial Coll., London) ; Häfliger, P (Zurich, ETH)
Electromagnetic calorimeters based on dense, scintillating crystals have the potential to achieve extremely good energy resolution. However, care must be taken to minimise systematic effects such as variation of light collection efficiency with depth in the crystal. [...]

Studies of PbWO4 Endcap Crystals Using a Hybrid Photomultiplier Tube / Britton, David (Imperial Coll., London) ; Ryan, Matthew John (Imperial Coll., London) ; Qu, Xiangdong (Imperial Coll., London)
A technique has been developed to measure the light collection uniformity of lead tungstate crystals for the CMS electromagnetic calorimeter. The use of a hybrid photomultiplier tube allows a precision measurement despite the intrinsically low light yield..
