High‐Resolution Elemental Record From the Holocene Sediments of an Alpine Lake in the Central Altai Mountains: Implications for Arctic Sea‐Ice Variations
Autor: Qing Sun, Andrei Daryin, Jiayu Zhao, Manman Xie, Fedor Darin, Yakov Rakshun, Youliang Su, Haowei Dong, Guoqiang Chu, Shuxian Wang
Publikováno v: Earth and Space Science, Vol 8, Iss 8, Pp n/a-n/a (2021)
Abstract It is well known that Arctic sea ice and Arctic amplification have played an important role in recent climate change in middle to high latitudes of the Northern Hemisphere. We present a high‐resolution elemental data set, spanning the past

It is well known that Arctic sea ice and Arctic amplification have played an important role in recent climate change in middle to high latitudes of the Northern Hemisphere. We present a high‐resolution elemental data set, spanning the past 9,000 ye

Gaussian random field generator for simulating partially coherent undulator radiation
Autor: Andrei Trebushinin, Gianluca Geloni, Yakov Rakshun, Svitozar Serkez
Publikováno v: Optica. 9:842
Wavefront propagation codes play pivotal roles in the design of optics at synchrotron radiation sources. However, they usually do not account for the stochastic behavior of the radiation field originating from shot noise in the electron beam. We prop

Spatial-frequency features of radiation produced by a step-wise tapered undulator
Autor: Yakov Rakshun, Gianluca Geloni, Mykola Veremchuk, Andrei Trebushinin, Svitozar Serkez
Publikováno v: Journal of Synchrotron Radiation
Spatial frequency radiation properties from a step-wise magnetic structure of an undulator are studied. This magnetic scheme is the most suitable for the superconducting undulators and provides the radiation properties that facilitate developing futu
