The behaviour of BGO sectors, designed for an electromagnetic calorimeter to be operated at up to 2 GeV, is considered in relation to the different terms that contribute to the overall BGO resolution and to the techniques that can be adopted to reduce them to a minimum. In particular, the measurements of light collection uniformity and energy resolution obtained on a large number of sectors are reported, and their effect on the overall BGO resolution analyzed.

Abstract
The behaviour of BGO sectors, designed for an electromagnetic calorimeter to be operated at up to 2 GeV, is considered in relation to the different terms that contribute to the overall BGO resolution and to the techniques that can be adopted to reduce them to a minimum. In particular, the measurements of light collection uniformity and energy resolution obtained on a large number of sectors are reported, and their effect on the overall BGO resolution analyzed.
