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 ne​≈5×1017 cm−3 by imaging Faraday rotation patterns imprinted on linea…

Time-Resolved Pulse Propagation in Glass in Single-Shot

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…

Observation of Plasma Bubble Structures in a GeV Laser-Plasma Accelerator

Yen-Yu Chang, Kathleen Weichman, Xiantao Cheng +8

We measure characteristics of plasma bubbles in GeV-class laser-plasma accelerators (LPAs) using Faraday rotation diagnostics. We extend these techniques, previously demonstrated f…

Bright 5 - 85 MeV Compton gamma-ray pulses from GeV laser-plasma accelerator and plasma mirror

J. M. Shaw, A. C. Bernstein, R. Zgadzaj +19

We convert a GeV laser-plasma electron accelerator into a compact femtosecond-pulsed γ-ray source by inserting a 100μm-thick glass plate ∼3 cm after the accelerator exit.…
