Helical jets driven by a ring of laser irradiation
Kian Orr, Brandon K. Russell, Kirill Lezhnin +5
Plasma jets are formed in various astrophysical systems as plasma is rapidly ejected from a source, with a subset of these jets being magnetized and having a helical structure. Her…
Laser ion acceleration from concave targets by subpicosecond pulses
K. V. Lezhnin, V. Ospina-Bohórquez, J. Griff-McMahon +6
Laser-driven proton acceleration provides a powerful route for generating ultrashort, high-charge proton beams. Many applications, including secondary neutron sources and inertial…
Evolution of laser-driven magnetic fields from proton tomography
J. Griff-McMahon, V. Valenzuela-Villaseca, C. A. Walsh +9
Self-generated magnetic fields are commonly produced in high-power laser-plasma interactions. These fields can inhibit plasma heat-flow which makes them important in inertial fusio…
Geometric scaling of laser-driven proton focusing from hemispherical foils
Jesse Griff-McMahon, Xavier Vaisseau, William Fox +7
We systematically characterize the focusing behavior of laser-driven proton beams from hemispherical targets of various diameters using mesh radiography. The proton focal location…
Ray-tracing laser-deposition model for plasma particle-in-cell simulation
Abdullah Hyder, Will Fox, Kirill Lezhnin +1
We develop a ray-tracing model for laser-plasma interaction suitable for coupling in-line into kinetic particle-in-cell plasma simulation. The model is based on inverse Bremsstrahl…
