Monochromation of pulsed electron beams with terahertz radiation at a planar mirror

Cecilia Abbamonte, Adam Bartnik, Jared Maxson

Exquisite control of electron beam energy is required for many electron spectroscopy and imaging applications. For both continuous and pulsed beams, the beam energy spread is funda…

Photoinduced twist and untwist of moiré superlattices in TMDC heterobilayers

C. J. R. Duncan, A. C. Johnson, I. Maity +15

Two-dimensional moiré materials are formed by artificially stacking atomically thin monolayers. A wealth of correlated and topological quantum phases can be engineered via precise…

Compensating slice emittance growth in high brightness photoinjectors using sacrificial charge

W. H. Li, A. C. Bartnik, A. Fukasawa +5

Achieving maximum electron beam brightness in photoinjectors requires detailed control of the 3D bunch shape and precise tuning of the beam focusing. Even in state-of-the-art desig…

Four-Dimensional Emittance Measurements of Ultrafast Electron Diffraction Optics Corrected Up to Sextupole Order

M. Gordon, W. H. Li, M. B. Andorf +7

Ultrafast electron diffraction (UED) is a technique in which short-pulse electron beams can probe the femtosecond-scale evolution of atomic structure in matter driven far from equi…
