From: Enhanced X-ray emission arising from laser-plasma confinement by a strong transverse magnetic field
(a) Spatial profile of the emitted X-rays as recorded by the VSG and integrated over the 0.65–1 keV spectral range, for a \(2 \times 10^{12}\) W/cm\(^2\) laser intensity on target. The plasma was immersed into the magnetic field with strength of 30 T (blue), 20 T (red, thin) or expanded freely in vacuum (black dashed). (b) Same but for the He\(_{\beta }\) spectral line measured by the FSSR spectrometer. (c) Evolution of the integrated plasma emission intensity (normalized to its value at \(B = 30\) T), integrated in space and time, and deduced from the intensity profiles shown in (a), as a function of the B-field strength.
