New techniques in electron energy-loss spectroscopy and energy-filtered imaging.
This article is a survey of hardware and software advances that promise to increase the power and sensitivity of electron energy-loss spectroscopy (EELS) and energy-filtered imaging (EFTEM) in a transmission electron microscope. Recent developments include electron-gun monochromators, lens-aberration correctors, and software for spectral sharpening, spectral processing and interpretation of fin...
متن کاملLattice imaging using plasmon energy-loss electrons in an energy-filtered transmission electron microscope
Lattice images formed by plasmon energy-loss electrons in an energy-filtered transmission electron microscope are compared for different experimental parameters. The image resolution is primarily determined by chromatic aberration which is controlled by the width of the energy selection window. With an energy slit 3 eV in width, the plasmon loss electron image shows the same resolution and cont...
متن کاملOptimal strategies for imaging thick biological specimens: exit wavefront reconstruction and energy-filtered imaging.
In transmission electron microscopy (TEM) of thick biological specimens, the relationship between the recorded image intensities and the projected specimen mass density is distorted by incoherent electron-specimen interactions and aberrations of the objective lens. It is highly desirable to develop a strategy for maximizing and extracting the coherent image component, thereby allowing the proje...
متن کاملDevelopment of epithermal neutron camera based on resonance-energy-filtered imaging with GEM
An epithermal neutron camera based on energy-filtered imaging with gas electron multipliers was developed. Epithermal neutron imaging is achievable without time-of-flight detection of neutrons by using a resonance filter and a thermal neutron absorber. This technique is applicable to compact accelerator-based neutron sources. Blurring of epithermal neutron images caused by neutron scattering in...
متن کاملFirst application of Cc-corrected imaging for high-resolution and energy-filtered TEM.
Contrast-transfer calculations indicate that C(c) correction should be highly beneficial for high-resolution and energy-filtered transmission electron microscopy. A prototype of an electron optical system capable of correcting spherical and chromatic aberration has been used to verify these calculations. A strong improvement in resolution at an acceleration voltage of 80 kV has been measured. O...
