[en] The energy spectrum of the synchrotron radiation emitted by the relativistic ring electrons in ELMP bumpy Torus (EBT) has been calculated for various classes of isotropic and anisotropic ring electron distribution functions. Calculations have been carried out for present (EBT-I/S) and planned (EBT-P) experiments. The ring temperatures in EBT-I and EBT-S are approx. 200 and approx. 500 keV, respectively. The projected ring temperature in EBT-P is approx. 1000 to 1500 keV. The calculations indicate that the radiation is predominantly in higher harmonics (l greater than or equal to γ²/2) and the radiation spectrum monotonically decreases and becomes almost flat at high frequencies, as observed in the experiments. With increasing temperature and anisotropy, the total emission increases, the slope of the spectrum decreases, and the peak of the spectrum moves to higher frequency. Correlations of calculated intensity variations with temperature, density, beta, anisotropy, etc., are given that can be used as a useful tool for comparison of theory and experiment, as well as in the determination of ring properties and scaling of the radiation with ring parameters
