Journal ArticleDOI
Design of an electron microscope phase plate using a focused continuous-wave laser
Holger Mueller,Jian Jin,Radostin Danev,John C. H. Spence,Howard A. Padmore,Robert M. Glaeser +5 more
TL;DR: In this paper, the authors proposed a Zernike phase contrast electron microscope that uses an intense laser focus to convert a phase image into a visible image, and studied the relativistic quantum theory of the phase shift caused by the laser-electron interaction.
Journal ArticleDOI
Enhancement of diffraction efficiency via higher-order operation of a multilayer blazed grating
TL;DR: The validity of this approach is shown and significant enhancement of diffraction efficiency of MBGs using higher-order diffraction is demonstrated using an optimized MBG with groove density of 2525 lines/mm at the wavelength of 13.4 nm.
Journal ArticleDOI
A multiplexed high-resolution imaging spectrometer for resonant inelastic soft X-ray scattering spectroscopy.
TL;DR: This spectrometer provides a completely parallel resonant inelastic X-ray scattering measurement at high spectral resolution over the energy bandwidth (∼5 eV) of a soft X-rays absorption resonance.
Journal ArticleDOI
Metal-insulator transitions in an expanding metallic fluid: particle formation kinetics.
Thornton E. Glover,G. D. Ackerman,Ali Belkacem,P.A. Heimann,Zahid Hussain,Richard W. Lee,Howard A. Padmore,Cédric Ray,Robert W. Schoenlein,W.F. Steele,David Young +10 more
TL;DR: These experiments probe constituents species and solidification kinetics occurring in the early moments of material ejection and provide insight into how particles arise in the current laser ablation regime.
Journal ArticleDOI
An ultrahigh-resolution soft x-ray microscope for quantitative analysis of chemically heterogeneous nanomaterials.
