“…However, to avoid a big energy loss at the edges of crystals ("dead zones" effect) one should also implement the defocusing of the edges from the interaction point. The defocusing scheme was previously implemented in the calorimeters of the Belle/Belle2 [2], BES [3], PANDA [4] and CMS [5] detectors. Since the pileup noise becomes significant at high luminosity, especially in the endcap, the usage of the crystals of pure CsI with short decay time of ∼ 30 ns is planned [6].…”

The paper presents a current status of the simulation of the pure CsI crystal calorimeter of the detector of charm-tau factory project in Novosibirsk. The calorimeter employs the scheme with the crystals focusing at the beams interaction point to obtain the optimal energy and coordinate resolutions. We present a detailed description of the calorimeter design, optimized using the specially developed parametrized crystal geometry generator. The report also presents the results for the coordinate and energy correction functions calculation. After application of these corrections the estimation of the photon energy and coordinate resolutions for the ideal conditions of negligibly small stochastic, electronic and pileup noises was performed. The π0 reconstruction efficiency and mass resolution depending on it's momentum were also determined.
