Southern territories of the Chernigov-Ryazan boundary in the XII-XV centuries

Introduction. In investigations of our science project features of historical development of the boundary territory of the South-East of the Chernigov and South-West of Ryazan lands are considered.Materials and methods. More than 450 monuments of the XI-XIV centuries are known on the territory. Among the most known archaeological objects the archaeological complex of Lavy on the Bystraya Sosna River is most important. In the late of the 11th c. this complex became the center of own rural area and the center of trade and craft activity.Results. We come to conclusion, that political borders of principalities were defined by various sources of settling of territory in the Pool of the Top Don. The analysis of the system of settlement at the microregional level allowed studying of settlements both in the system of landscape and within the settlement expanse.Conclusion. From the end of the 11th – till the middle of the 13th cc. the lands of the Right bank of the Top Don were occupied from the principality of Chernigov-Severskiy. The lands across the Don River and its Left bank were occupied from territory of the principality of Ryazan. During the second half of the 13th – 14th cc. the Right bank of the Top Don was in structure of the principalities of Verkhovskye, and its Left bank was in the structure of the principality of Ryazan. To the middle of the 12th century in Top Don the border between principalities was established passed from source of the Don River to the mouth of the Bystraya Sosna River

Energy deposition studies for the High-Luminosity Large Hadron Collider inner triplet magnets

A detailed model of the High Luminosity LHC inner triplet region with new large-aperture Nb3Sn magnets, field maps, corrector packages, and segmented tungsten inner absorbers was built and implemented into the FLUKA and MARS15 codes. In the optimized configuration, the peak power density averaged over the magnet inner cable width is safely below the quench limit. For the integrated luminosity of 3000 fb-1, the peak dose in the innermost magnet insulator ranges from 20 to 35 MGy. Dynamic heat loads to the triplet magnet cold mass are calculated to evaluate the cryogenic capability. In general, FLUKA and MARS results are in a very good agreement.Comment: 24 p

Machine-Related Backgrounds in the SiD Detector at ILC

With a multi-stage collimation system and magnetic iron spoilers in the tunnel, the background particle fluxes on the ILC detector can be substantially reduced. At the same time, beam-halo interactions with collimators and protective masks in the beam delivery system create fluxes of muons and other secondary particles which can still exceed the tolerable levels for some of the ILC sub-detectors. Results of modeling of such backgrounds in comparison to those from the e+ e- interactions are presented in this paper for the SiD detector.Comment: 29 pages, 34 figures, 7 table
