X-ray spectroscopy application for magnetic field and electron beam measurements in laser produced plasma

Temperature and density gradients, parametric instabilities which are common to laser produced plasma, can lead to both spontaneous magnetic field and electron beam generation. Strong magnetic field splits lines, suprathermal electrons are of great importance in energy transition processes and in plasma emission spectra formation. The paper presents magnetic field strength and suprathermal electron energy measurement methods, based on investigation of X-ray line spectra, emitted from laser produced plasma. A simple mechanism of magnetic field generation based on cumulative stream formation is presented.
