Abstract
Using matrices of lead tungstate crystals, energy resolutions better t han 0.6% at 100 GeV have been achieved in the test beam in 1995. It ha s been demonstrated that a lead tungstate electromagnetic calorimeter read out by avalanche photodiodes can consistently achieve the excelle nt energy resolutions necessary to justify its construction in the CMS detector. The performance achieved has been understood in terms of th e properties of the crystals and photodetectors.
