Spatiotemporal oscillation of an ion beam extracted from a potential-oscillating plasma source

New Journal of Physics, 2019
A radiofrequency oscillation is successfully superimposed on a plasma potential of a filamented source plasma in an ion beam source while maintaining a constant plasma density, in order to investigate effects of oscillating source plasma potential on an ...

X-ray beam monitoring and wavelength calibration using four-beam diffraction

Journal of Synchrotron Radiation, 2022
Rigorous dynamical theory calculations show that four-beam diffraction (4BD) can be activated only by a unique photon energy and a unique incidence direction. Thus, 4BD may be used to precisely calibrate X-ray photon energies and beam positions. Based on
