Experimental demonstration of Flying-Focus enhanced Thomson scattering
E. Gerstmayr, C. Mariani, R. Fitzgarrald +23
We report the experimental demonstration of a spatiotemporally engineered "Flying-Focus" laser pulse for enhanced x-ray generation in relativistic Thomson scattering. A combination…
Stability and optical quality of "windmill"-formed 8CB liquid crystal films for replenishable plasma mirrors
A. Vazquez, A. Jewell, M. Cole +16
Liquid crystal (LC) film plasma mirrors (PMs) based on 4-octyl-4'-cyanobiphenyl (8CB) are an enabling technology for reflecting high-fluence laser pulses. These freestanding LC fil…
Revealing Laser and Electron Beam Evolution in 10-GeV-class Laser-Plasma Accelerators
H. Tang, A. Picksley, C. Benedetti +12
Guiding relativistically intense laser pulses in low-density plasmas enables extended acceleration lengths in laser-plasma accelerators (LPAs), allowing for the production of multi…
Longitudinal tapering in meter-scale gas jets for increased efficiency of laser plasma accelerators
R. Li, A. Picksley, C. Benedetti +10
Modern laser plasma accelerators (LPAs) often require plasma waveguides tens of cm long to propagate a high-intensity drive laser pulse. Tapering the longitudinal gas density profi…
Modeling and Design of Compact, Permanent-Magnet Transport Systems for Highly Divergent, Broad Energy Spread Laser-Driven Proton Beams
J. T. De Chant, K. Nakamura, Q. Ji +8
Laser-driven (LD) ion acceleration has been explored in a newly constructed short focal length beamline at the BELLA petawatt facility (interaction point 2, iP2). For applications…
