Here, we report the first direct observation by Lorentz microscopy of the interaction between vortices and columnar defects in ion-irradiated Bi2Sr2CaCu2O8+δ (Bi-2212) thin films by …

Aug 5, 2014 · Pushing the limits in temporal resolution for transmission electron microscopy (TEM) requires a revolutionary change in the electron source technology. In this paper, we …

Transmission electron microscopy (TEM) with in situ ion irradiation allows real-time observation of defect formation and evolution in a single specimen. Advances in video and camera...

In 1988, Maruse and Shimoyama obtained a lMV-field-emission beam using their 1.25MV-STEM connected to a field-emission gun. Since then, continuous improvements in beam brightness …

Nov 21, 2018 · In this study, the microstructural changes in irradiated W–1 wt%Pr 2 O 3, W–1 wt%La 2 O 3, W–1 wt%TiC and W–1 wt%ZrC specimens by 1 MeV Fe + ion irradiation to …

The evolution under deformation of symmetrical GBs in Si and Ge has been studied both by in-situ TEM and HREM. The influence of the strain conditions (tension or compression) on the …

Jan 1, 1999 · Lead liquid metal ion sources (LMISs) were operated using a special specimen holder in situ in a 1 MeV TEM. The dynamics of the tip shape have been observed as a …

The high-b section of the accelerator is a PWT structure operating in a standing wave, TEM mode. The average accelerating field of this section is 2.42 MeV/m with a peak structure …

At Cadarache, ITER relevant research is performed regarding the development of a 1MeV high beam current density (10-20mA/cm2) electrostatic accelerator (SINGAP).

In TEM observation of the films, the visibility of the fringes depends on the coherence of the electron wave and the overall stability of the microscope. Here, we calculated chromatic …
