A wakefield experiment at the Argonne Wakefield Accelerator (AWA) facility utilizes flat electron beams with highly asymmetric transverse emittances to drive plasma wakefields in the underdense regime. These beams create elliptical blowout structures, producing asymmetric transverse focusing forces. The experiment utilizes a compact 4-cm-long capillary discharge plasma source developed at...
Timestamping electron pulses is a promising strategy for improving the overall temporal resolution of the MeV UED beamline. Timestamping can be achieved with a time-varying deflection of the beam: the deflection angle records the time of arrival of the pulse, from which it is possible to accurately read back the pump-probe delay shot-by-shot. This proposal targets the demonstration of...
Generation of ultralow-emittance electron beams with high brightness is critical for several applications such as ultrafast electron diffraction, microscopy, and advanced accelerator techniques. By leveraging the differences in work function and electronic structure between different materials, we enabled spatially localized photoemission, resulting in picometer-scale emittance from a flat...
