Optical design for increased interaction length in a high gradient dielectric laser accelerator
D. Cesar, J. Maxson, P. Musumeci +3
We present a methodology for designing and measuring pulse front tilt in an ultrafast laser for use in dielectric laser acceleration. Previous research into dielectric laser accele…
Enhanced energy gain in a dielectric laser accelerator using a tilted pulse front laser
D. Cesar, J. Maxson, P. Musumeci +4
Using an 800 nm, 45 fs pulse-front-tilted laser we demonstrate a record 315 keV energy gain in a dual grating dielectric laser accelerator (DLA) and average accelerating gradients…
Demonstration of single-shot picosecond time-resolved MeV electron imaging using a compact permanent magnet quadrupole based lens
D. Cesar, J. Maxson, P. Musumeci +7
We present the results of an experiment where a short focal length (~ 1.3 cm) permanent magnet electron lens is used to image micron-size features of a metal sample in a single sho…
Ultrafast quantum dynamics driven by the strong space charge field of a relativistic electron beam
D. Cesar, A. Acharya, J. P. Cryan +7
In this article, we illustrate how the Coulomb field of a highly relativistic electron beam can be shaped into a broadband pulse suitable for driving ultrafast and strong-field phy…
Electron beam shaping via laser heater temporal shaping
D. Cesar, A. Anakru, S. Carbajo +6
Active longitudinal beam optics can help FEL facilities achieve cutting edge performance by optimizing the beam to: produce multi-color pulses, suppress caustics, or support attose…
Nonlinear response in high-field dielectric laser accelerators
D. Cesar, S. Custodio, J. Maxson +9
Laser powered dielectric structures achieve high-gradient particle acceleration by taking advantage of modern laser technology capable of producing electric fields in excess of 10G…
