Workshop on Electron Probe MicroAnalysis

Vern Robertson, Peter McSwiggen
Tuesday, March 20, 2018 - 9:30am to 3:00pm

This workshop is sponsored by PINSE/NFCF, JEOL and Three Rivers Microscopy Society (3RMS).  

The workshop will provide an introduction to the world of electron microprobe and also cover some more advanced applications such as low keV analysis and effects of contamination.  Some of these topics are also of interest to EDS users. This workshop is for anyone, and we welcome those who have zero knowledge of EPMA but might be interested in applications to your own research.  EPMA is similar to EDS, but offers more elemental precision, with higher peak to background ratios and easier...

Ultrafast Microscopy: Imaging Light with Photoelectrons on the Nano-Femto Scale

Experimental methods for ultrafast microscopy are advancing rapidly. Promising methods combine ultrafast laser excitation with electron-based imaging or rely on super-resolution optical techniques to enable probing of matter on the nano–femto scale. Among several actively developed methods, ultrafast time-resolved photoemission electron microscopy provides several advantages, among which the foremost are that time resolution is limited only by the laser source and it is immediately capable of probing of coherent phenomena in solid-state materials and surfaces. Here we present recent progress in interference imaging of plasmonic phenomena in metal nanostructures enabled by combining a broadly tunable femtosecond laser excitation source with a low-energy electron microscope.

Tevis Jacobs Awarded NSF Grant to Enable Visualization of Atomic Structure

  • By Aude Marjolin
  • 26 September 2016

Tevis Jacobs received an NSF grant to observe and measure nanoscale contact inside an electron microscope, enabling for the first time the visualization of the atomic structure of the component materials while they are in contact.

Jacobs will serve as principal investigator of the study, “Collaborative Research: Understanding the Formation and Separation of Nanoscale Contacts,” which received $298,834 over three years.

He and his team will collaborate with the University of California-Merced. As the electron microscopy examines the materials’ surfaces, the experiments using molecular dynamics computer simulations will be replicated to reveal atomic-scale.
