Abstract: A large size PbF₂ crystal was grown with the modified non-vacuum Bridgeman method. Itpossesses outstanding Cherenkov radiation properties. Its cut-off edge is as short as 245urn, theenergy resolution is superior to 3.2%/E^1/2, and the radiation damage is weak and can be cured byannealing with 365um filtered light.

Key words: PbF₂ crystal, Cherenkov radiation, cut-off edge, energy resolution, radiation damage
