X-ray luminescence and scintillation characteristics of CsPbBr$_3$ crystal from the perovskites family were investigated over the temperature range of 7-200 K. At low temperatures CsPbBr$_3$ was found to be a very bright scintillator with the fast response demonstrating a very short decay time constant 1 ns at 7 K. The light output was measured to be 109 000 $\pm$22 000 ph/MeV at excitation with $α$-particles of $^{241}$Am. The obtained results testify that CsPbBr$_3$ is a very potent scintillation material, which would compete with the commercial analogues in the case of the cryogenic applications. Besides, the study has clarified the origin of the intense slow component observed below 70 K that would be considered an obvious disadvantage for the scintillator applications, since it causes an afterglow. It has been shown that the corresponding radiation is due to the impurities and capture centers. This implies possibility for elimination of the slow component by optimization of the material using an improved growth process.

Key words: scintillation, light output, decay time, luminescence, detectors of ionizing radiation, perovskite, cryogenic applications
