Abstract
The experiment with the prototype of liquid krypton electromagnetic ca lorimeter for the KEDR detector is described. The experiment was carri ed out at the VEPP-4M collider at the tagged photon beam. The tagged p hotons were obtained in the energy region 50-625 MeV using the ROKK-1M facility. The edges of the bremsstrahlung spectra were used for the e nergy resolution measurement in the high-energy region up to 4500 MeV. The energy resolution comparable with the resolution of the best crys tal calorimeters and the excellent spatial resolution (similar to 1 mm ) have been obtained. The results are in good agreement with the Monte -Carlo simulation.
