Thomson scattering of coherent diffraction radiation by an electron bunch.
This paper considers the process of Thomson scattering of coherent diffraction radiation (CDR) produced by the preceding electron bunch in the accelerator onto one of the subsequent bunches. It is shown that the yield of scattered hard photons is proportional to N(3)(e), where N(e) is the number of electrons per bunch. A geometry is chosen for the CDR generation and an expression is obtained fo...
متن کاملSimulation of Synchrotron Radiation in an Electron Storage Ring
We studied a method of using symplectic integrator to simulate incoherent synchrotron radiation in an electron storage ring. The simulation includes both classical radiation and its quantum uctuations. We found that the emission process of photon using a compound Poisson process cannot be applied to the fourth-order integrator because it has negative path length which implies a negative n umber...
متن کاملElectron Diffraction Electron Diffraction
This guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to you for interpreting the transmission diffraction pattern produced by scattering electrons off a thin film target of polycrystalline aluminium. The apparatus also contains samples with hexagonal structures. These are pyrolytic graphite targets, and are available both as single crystals and in polycr...
متن کاملDiffraction properties of periodic lattices under free electron laser radiation.
In this Letter, we report the pioneering use of free electron laser radiation for the investigation of periodic crystalline structures. The diffraction properties of silver behenate single nanocrystals (5.8 nm periodicity) with the dimensions of 20 nm x 20 nm x 20 microm and as powder with grain sizes smaller than 200 nm were investigated with 8 nm free electron laser radiation in single-shot m...
متن کاملUltrafast electron diffraction using an ultracold source
The study of structural dynamics of complex macromolecular crystals using electrons requires bunches of sufficient coherence and charge. We present diffraction patterns from graphite, obtained with bunches from an ultracold electron source, based on femtosecond near-threshold photoionization of a laser-cooled atomic gas. By varying the photoionization wavelength, we change the effective source ...
