A thick (200 m) rock salt mass covering Late Archean granitoids was exposed for the first time in the Early Proterozoic volcanogenic-sedimentary formations in the Onega trough of the east Baltic Shield by the Onega parametric well. The mineral compos

Dependence of the SCR proton flux estimate on radio burst parameters

Autor: V. F. Melnikov, L. I. Tsvetkov, E. A. Isaeva

Publikováno v: Bulletin of the Crimean Astrophysical Observatory. 106:26-30

We present results suggesting that the accuracy of estimating the solar cosmic-ray (SCR) proton flux from μ-burst parameters is much higher for proton events characterized by a low level of post-burst increase (PBI) in the μ-burst flux, a powerful

Microwave radiation of solar coronal holes: Results of CrAO RI RT-22 observations in 2003–2006

Autor: L. I. Tsvetkov, S. A. Samis’ko

Publikováno v: Bulletin of the Crimean Astrophysical Observatory. 104:59-66

Results of the identification of solar coronal holes (CH) with radio brightness depressions and excesses are presented, which were obtained as a result of RT-22 observations at 2.0–3.5 cm in 2004–2006. Microwave radiation inhomogeneities in CHs,

63Ni-based β-electric current source

Autor: V. V. Zaddé, N. S. Petrenko, V. V. Gusev, A. A. Pustovalov, A. V. Tikhomirov, L. A. Tsvetkov

Publikováno v: Atomic Energy. 103:939-945

The possibility of developing a β-electric atomic battery with microwatt power based on 63Ni with a lifetime of at least 30 years is analyzed. A method is proposed for large-scale commercial production of 63Ni with concentration 80–90% in the fina

Variations of microwave emission from solar active regions

Autor: Yu. T. Tsap, L. I. Tsvetkov, Yu. G. Kopylova, Yu. A. Nagovitsyn, G.B. Gelfreikh, T. B. Goldvarg

Publikováno v: Astronomy Letters. 30:489-495

Based on observational data obtained with the RT-22 Crimean Astrophysical Observatory radio telescope at frequencies of 8.6 and 15.4 GHz, we investigate the quasi-periodic variations of microwave emission from solar active regions with periods Tp
