The fine structure of the synchrotron-Cherenkov radiation of spectral distribution of the radiation power of one and four electrons moving in a spiral in a transparent medium with relativistic transversal velocity component (the component perpendicular to the magnetic field) is researched. The oscillations and superradiance in the synchrotron-Cherenkov radiation spectrum of four electrons at di...

Here we report on a synchrotron for neutral molecules that consists of two hexapole focusers bent into a torus. By switching the voltages applied to the two half-rings, polar molecules can be confined in tight packets for up to a second as they revolve around the ring. In this article, the operation and trapping parameters of the molecular synchrotron are discussed. We plan to use a molecular s...

Turning on a `pretzel' , or any closed orbit distortion, can substantially alter the path of synchrotron radiation (SR), in some instances causing it to strike components not designed to absorb the radiation. In this paper I develop equations useful in determining the source position and angle of dipole SR as a function of the pretzel amplitude and angle. Formula for linear power deposition and...

X-Ray Refraction Topography techniques are based on Ultra Small Angle Scattering by micro structural elements causing phase related effects like refraction and total reflection at a few minutes of arc as the refractive index of X-rays is nearly unity. The refraction contrast is several times higher than “true absorption” and results in images of cracks, pores and fibre debonding separations bel...
