Enhanced X-ray emission arising from laser-plasma confinement by a strong transverse magnetic field
Abstract We analyze, using experiments and 3D MHD numerical simulations, the dynamic and radiative properties of a plasma ablated by a laser (1 ns, 10 $$^{12}$$ 12 –10 $$^{13}$$ 13 W/cm $$^2$$ 2 ) from a solid target as it expands into a homogeneous, strong magnetic field (up to 30 T) that is transv...
