Study of edge radiation at HiSOR storage ring

“…when it passes through the region of a rapid change of magnetic field amplitude. It was experimentally discovered in 1979 simultaneously and independently using the Super Proton Synchrotron (CERN, Geneva) [1,2] and the electron synchrotrons ''Sirius'' (Tomsk, Russia) [3][4][5] and ''Pakhra'' (Moscow, Russia) [6]. Notice that the physics of ER in proton storage rings [7][8][9][10] differs essentially from that in electron storage rings though some similarities in their properties can be found.…”

IR–UV edge radiation at Siberia-2 storage ring

“…It was experimentally discovered in the late 1970s simultaneously and independently at Super Proton Synchrotron (SPS, CERN, Geneva) [1,2] and at the electron synchrotron ''Sirius'' (INP, Tomsk, Russia) [3][4][5]. Notice that the nature of ER emitted by protons [6][7][8] differs radically from ER emitted by electrons, though some similarities in their spectral characteristics can be found.…”

Shift-Scale Invariance of Electromagnetic Radiation

“…It was discovered independently at the SPS proton synchrotron at CERN (Bossart et al, 1979(Bossart et al, , 1981 and the Tomsk electron synchrotron "Sirius" (Nikitin et al, 1980(Nikitin et al, , 1981. Notice that the physics of edge radiation in proton storage rings (Coisson, 1979;Smolyakov, 1985Smolyakov, , 1986 differs essentially from that in electron storage rings (Bessonov, 1981;Chubar & Smolyakov, 1993;Bosch, 1997;Geloni et al, 2009) though some similarities in their properties can be found.…”
