This article reviews photoemission experiments that simultaneously resolve at least two of
the following degrees of freedom: space (real and momentum space), time (intrinsic time …

We present a method for producing sub-100 fs electron bunches that are suitable for single-
shot ultrafast electron diffraction experiments in the 100 keV energy range. A combination of …

Parity-violating electron-scattering experiments represent an important focus of the nuclear
physics experimental program at the Continuous Electron Beam Accelerator Facility …

Abstract Machine learning (ML) tools are able to learn relationships between the inputs and
outputs of large complex systems directly from data. However, for time-varying systems, the …

Progress in laser wakefield accelerators indicates their suitability as a driver of compact free-
electron lasers (FELs). High brightness is defined by the normalized transverse emittance …

We present a detailed study of the six-dimensional phase space of the electron beam
produced by the Cornell Energy Recovery Linac Photoinjector, a high-brightness, high …

We utilize a Fourier transformation-based representation of Maxwell's equations to develop
physics-constrained neural networks for electrodynamics without gauge ambiguity, which …

Plasma-based technology promises a tremendous reduction in size of accelerators used for
research, medical, and industrial applications, making it possible to develop tabletop …

We present a physics-constrained neural network (PCNN) approach to solving Maxwell's
equations for the electromagnetic fields of intense relativistic charged particle beams. We …

The origin of beam disparity in emittance and betatron oscillation orbits, in and out of the
polarization plane of the drive laser of laser-plasma accelerators, is explained in terms of …
