TL;DR: The generation of ultrashort radiation pulses became possible due to specific tailoring of the bunch charge distribution and a complete characterization of the linear and nonlinear modes of the SASE FEL operation was performed.

TL;DR: In this paper, the statistical properties of the FEL radiation have been studied for different amplification regimes as well as behind a narrow-band monochromator and found to be in good agreement with the results of numerical simulations.
Journal ArticleDOI
Between Linguistics and Ideology: Lev Iakubinskii on Social Dialects
TL;DR: The authors examines the origins and components of Iakubinskii's sociolinguistic conception and considers to what extent his engagement with this topic was influenced by the complex political and ideological context of the early Soviet period.
