Physics-Informed Drift Diagnosis for Laser-Plasma Accelerator Operations
Ou Labun, Calin Hojbota, Mara Klebonas +4
Laser-plasma accelerators (LPAs) sustain accelerating gradients of order , but routine operation remains difficult: electron beam metrics drift over an operatin…
High-charge 10 GeV electron acceleration in a 10 cm nanoparticle-assisted hybrid wakefield accelerator
Constantin Aniculaesei, Thanh Ha, Samuel Yoffe +23
In an electron wakefield accelerator, an intense laser pulse or charged particle beam excites plasma waves. Under proper conditions, electrons from the background plasma are trappe…
Faraday rotation study of plasma bubbles in GeV wakefield accelerators
Y. Y. Chang, X. Cheng, A. Hannasch +8
We visualize plasma bubbles driven by 0.67 PW laser pulses in plasma of density by imaging Faraday rotation patterns imprinted on linea…
Stable Positron Acceleration in Thin, Warm, Hollow Plasma Channels
T. Silva, L. D. Amorim, M. C. Downer +4
Hollow plasma channels are attractive for lepton acceleration because they provide intrinsic emittance preservation regimes. However, beam breakup instabilities dominate the dynami…
Nonlinear Inverse Compton Scattering from a Laser Wakefield Accelerator and Plasma Mirror
A. Hannasch, M. LaBerge, R. Zgadzaj +7
We generate inverse Compton scattered X-rays in both linear and nonlinear regimes with a 250 MeV laser wakefield electron accelerator and plasma mirror by retro-reflecting the unus…
Compact Spectral Characterization of 5-500 MeV X-rays from the Texas Petawatt Laser-Driven Plasma Accelerator
A. Hannasch, L. Lisi, J. Brooks +11
We reconstruct spectra of secondary x-rays generated from a 500 MeV - 2 GeV laser plasma electron accelerator. A compact (7.5 7.5 15 cm), modular x-ray calorimete…
Compact Spectroscopy of keV to MeV X-rays from a Laser Wakefield Accelerator
A. Hannasch, A. Laso Garcia, M. LaBerge +12
We reconstruct spectra of secondary X-rays from a tunable 250-350 MeV laser wakefield electron accelerator from single-shot X-ray depth-energy measurements in a compact (7.5 $\time…
Evolution of the self-injection process in the transition of an LWFA from self-modulation to blowout regime
Prabhat Kumar, Kwangmin Yu, Rafal Zgadzaj +5
Long wavelength infrared (LWIR) laser driven plasma wakefield accelerators are investigated here in the self-modulated laser wakefield acceleration (SM-LWFA) and blowout regimes us…
Dissipation of electron-beam-driven plasma wakes
Rafal Zgadzaj, Zhengyan Li, M. C. Downer +10
Metre-scale plasma wakefield accelerators have imparted energy gain approaching 10 gigaelectronvolts to single nano-Coulomb electron bunches. To reach useful average currents, howe…
Electron bunch generation from a plasma photocathode
Aihua Deng, Oliver Karger, Thomas Heinemann +25
Plasma waves generated in the wake of intense, relativistic laser or particle beams can accelerate electron bunches to giga-electronvolt (GeV) energies in centimetre-scale distance…

Alex Lumpkin, Maxwell LaBerge, Donald Rule +10
We report initial observations of coherent optical transition radiation interferometry (COTRI) patterns generated by microbunched electrons from laser-driven plasma accelerators (L…

Yen-Yu Chang, Zhengyan Li, James Welch +3
We report time-resolved pulse self-steepening and temporal splitting in flint glass (SF11) in single-shot using broadband frequency-domain streak camera (B-FDSC). The broadband ($6…
