Absolute keV X-ray yield and conversion efficiency in over dense Si petawatt laser plasma
Sergey N. Ryazantsev, Artem S. Martynenko, Maksim V. Sedov +15
Laser-produced plasmas are bright, short sources of X-rays often used for time-resolved imaging and spectroscopy. Absolute measurement requires accurate knowledge of laser-to-x-ray…
Identification of electrostatic two-stream instabilities associated with a laser-driven collisionless shock in a multicomponent plasma
Youichi Sakawa, Yutaka Ohira, Rajesh Kumar +3
Electrostatic two-stream instabilities play essential roles in an electrostatic collisionless shock formation. They are a key dissipation mechanism and result in ion heating and ac…
Observation and modelling of Stimulated Raman Scattering driven by an optically smoothed laser beam in experimental conditions relevant for Shock Ignition
G. Cristoforetti, S. Huller, P. Koester +20
We report results and modelling of an experiment performed at the TAW Vulcan laser facility, aimed at investigating laser-plasma interaction in conditions which are of interest for…
Proton Radiography in Background Magnetic Fields
Christopher Arran, Christopher P. Ridgers, Nigel C. Woolsey
Proton radiography has proved increasingly successful as a diagnostic for electric and magnetic fields in high energy density physics experiments. Most experiments use target-norma…
Measurement of magnetic cavitation driven by heat flow in a plasma
Christopher Arran, Adam Dearling, Philip Bradford +13
We describe the direct measurement of the expulsion of a magnetic field from a plasma driven by heat flow. Using a laser to heat a column of gas within an applied magnetic field, w…
Ion acceleration at two collisionless shocks in a multicomponent plasma
Rajesh Kumar, Youichi Sakawa, Takayoshi Sano +3
Intense laser-plasma interactions are an essential tool for the laboratory study of ion acceleration at a collisionless shock. With two-dimensional particle-in-cell calculations of…
