Dephasingless laser wakefield acceleration in a plasma waveguide
J. P. Palastro, K. G. Miller, C. D. Arrowsmith +10
Laser wakefield accelerators (LWFAs) provide extremely large accelerating gradients for compact electron accelerators and photon sources but are limited by dephasing, where trapped…
Generalized multi-dimensional conservation laws for stimulated Raman and Brillouin scattering in a density gradient
Vijay Patel, Sarah Chase, Frank S. Tsung +3
Generalized local and multi-dimensional conservation laws of action, energy, momentum, and angular momentum are derived for stimulated Raman (SRS) and Brillouin backscattering (SBS…
Differentiable Programming for Plasma Physics: From Diagnostics to Discovery and Design
A. S. Joglekar, A. G. R. Thomas, A. L. Milder +3
Differentiable programming, enabled by automatic differentiation (AD), provides a robust framework for gradient-based optimization in computational plasma physics. While optimizati…
Robust direct laser acceleration of electrons with flying-focus laser pulses
Talia Meir, Kale Weichman, Alexey Arefiev +2
Direct laser acceleration (DLA) offers a compact source of high-charge, energetic electrons for generating secondary radiation or neutrons. While DLA in high-density plasma optimiz…
Path to a Single-Stage, 100-GeV Electron Beam via a Flying-Focus-Driven Laser-Plasma Accelerator
J. L. Shaw, M. V. Ambat, K. G. Miller +9
Dephasingless laser wakefield acceleration (DLWFA), a novel laser wakefield acceleration concept based on the recently demonstrated "flying focus" technology, offers a new paradigm…
Arbitrary-velocity laser pulses in plasma waveguides
J. P. Palastro, K. G. Miller, M. R. Edwards +4
Space-time structured laser pulses feature an intensity peak that can travel at an arbitrary velocity while maintaining a near-constant profile. These pulses can propagate in unifo…
