Studies by Berkeley Lab scientists of electron beam quality in laser plasma accelerators include novel tests for slice-energy spread

Part Two: Slicing through the electron beam

Wim Leemans of Berkeley Lab’s Accelerator and Fusion Research Division heads LOASIS, the Laser and Optical Accelerator Systems Integrated Studies, an oasis indeed for students pursuing graduate studies in laser plasma acceleration (LPA). Among the most promising applications of future table-top accelerators are new kinds of light sources, in which their electron beams power free electron lasers. (more…)

Yale’s acquisition of a powerful new transmission electron microscope (TEM) is expected to transform researchers’ ability to examine and manipulate atom-scale materials and devices on campus.

The approximately $2 million, state-of-the-art microscope offers atomic resolution for both physical structure and chemical composition, as well as significantly faster processing times than other devices on campus. It is the first unit of this specific TEM model acquired for university laboratory use. (more…)
