    "abstract": "A Shashlyk calorimeter prototype for the KOPIO experiment has been\nconstructed and experimentally tested. The energy resolution of about\n4%/sqrt(E(GeV)) for 0.5-2.0 GeV/c positrons was obtained. Based on this results\nas well as on the results of special measurements, a Monte-Carlo model of the\nShashlyk module response was developed. This model, including the effects of\nshower evolution, light collection in scintillator plates, light attenuation in\nfibers, quantum efficiency of the photodetector, thresholds and noises in the\nreadout system is consistent with experimental results. Possible improvment of\nthe Shashlyk energy resolution up to 3%/sqrt(E(GeV)), the level required by\nKOPIO experiment, are discussed.",
