Scientists tailor electron vortex beams with customizable shapes

by

A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography. In recent years, the scientific community has witnessed a notable breakthrough in the study and development of electron vortices. Electron vortices are electron beams that carry orbital angular momentum, meaning the electrons move not only in their propagation direction … Read more

Study links surface roughness to performance in superconducting radiofrequency cavities

by

With every new particle accelerator built for research, scientists have an opportunity to push the limits of discovery. But this is only true if new particle accelerators deliver the desired performance—no small feat in a world where each new machine is a first of its particular kind. At each project opportunity, researchers try to refine … Read more

Jefferson Lab achieves record-breaking precision in electron beam polarimetry

by

Scientists are getting a more detailed look than ever before at the electrons they use in precision experiments. Nuclear physicists with the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility have shattered a nearly 30-year-old record for the measurement of parallel spin within an electron beam—or electron beam polarimetry, for short. The achievement sets … Read more

Researchers achieve steering and acceleration in “accelerator on a chip” technology

by

Stanford researchers are getting closer to building a tiny electron accelerator based on “accelerator-on-a-chip” technology with broad potential applications in studying physics as well as medical and industrial uses. The researchers have demonstrated that a silicon dielectric laser accelerator, or DLA, can now both speed up and confine electrons, creating a focused beam of high-energy … Read more

New imaging method reveals the secret Behind ultra-strong alloys for turbines, reactors, and space exploration

by

A new class of metallic materials with potential applications in airplane turbines, nuclear reactors and equipment for space exploration can withstand extreme temperatures and resist fractures, but scientists haven’t understood why until now. According to a new study co-led by Penn State researchers, the answer could relate to the material’s short-range order, or the local … Read more

Electron beam technology demonstrates potential for destroying PFAS in water

by

Using nonstick cookware to fry your bacon and eggs can make your life easier at that moment, but scientists believe there may be long-term consequences because the chemicals used to make it nonstick are so difficult to destroy. Perfluoroalkyl and polyfluoroalkyl substances—commonly known as PFAS and often called forever chemicals—are everywhere. PFAS, a suite of … Read more
