Holographic generation of highly twisted electron beams.
Free electrons can possess an intrinsic orbital angular momentum, similar to those in an electron cloud, upon free-space propagation. The wave front corresponding to the electron's wave function forms a helical structure with a number of twists given by the angular speed. Beams with a high number of twists are of particular interest because they carry a high magnetic moment about the propagatio...

متن کاملGeneration and application of bessel beams in electron microscopy.
We report a systematic treatment of the holographic generation of electron Bessel beams, with a view to applications in electron microscopy. We describe in detail the theory underlying hologram patterning, as well as the actual electron-optical configuration used experimentally. We show that by optimizing our nanofabrication recipe, electron Bessel beams can be generated with relative efficienc...
متن کاملBenchmarking of Siemens Linac in Electron Modes: 8-14 MeV Electron Beams
Introduction: Radiation therapy using electron beams is a promising method due to its physical dose distribution. Monte Carlo (MC) code is the best and most accurate technique for forespeaking the distribution of dose in radiation treatment of patients.Materials and Methods: We report an MC simulation of a linac head and depth dose on central axis, along with profile calculations. The purpose o...
متن کاملElectron Avalanche Statistics
Since the times of the founders of streamer theory — Raether [1], Loeb [2] and Meek [3] — a special attention has been paid to high populated electron avalanches possessing potential to overgrowing into streamers. One of the basic problem that has not been resolved so far concerns anomalous statistical behavior of big avalanches with electron populations n > 10. The mentioned anomaly consists i...
