This work discusses the development of x-ray and gamma-ray sources based on laser-wakefield acceleration (LWFA) in the self-modulated regime. These sources are developed for probing high energy density (HED) science experiments at large-scale laser f

Although recent years have seen significant advances in the spatial resolution possible in the transmission electron microscope (TEM), the temporal resolution of most microscopes is limited to video rate at best. This lack of temporal resolution mean

The PLEIADES (Picosecond Laser-Electron Inter-Action for the Dynamical Evaluation of Structures) facility has produced first light at 70 keV. This milestone offers a new opportunity to develop laser-driven, compact, tunable x-ray sources for critical

In Compton scattering light sources, a laser pulse is scattered by a relativistic electron beam to generate tunable x and gamma rays. Because of the inhomogeneous nature of the incident radiation, the relativistic Lorentz boost of the electrons is mo

Compton-scattering is a well-known process, observed and described by Arthur H. Compton in 1924, where the energy of an incident photon is modified by an inelastic scatter with matter (Compton, 1923). In 1948, Feenberg and Primakoff presented a theor

We report the design and current status of a monoenergetic laser-based Compton scattering 0.5-2.5 MeV γ-ray source. Previous nuclear resonance fluorescence results and future linac and laser developments for the source are presented.

A dynamic transmission electron microscope (DTEM) has been designed and implemented to study structural dynamics in condensed matter systems. The DTEM is a conventional in situ transmission electron microscope (TEM) modified to drive material process
