摘要: We present spectroscopic measurements in which utilized are line-intensity ratios the near-uv to measure electron energies of several hundred eVs, usually necessitates use emission soft x-ray region. The main intensity ratio selected is B III transition 1s 2 2s S 1/2 -1s 2p P 3/2 2066 A and IV 1s2s 3 S1-1s2p P2 2822 A. detailed atomic-kinetics modeling made demonstrate usefulness this atomic system for studying transient, ionizing plasmas. Here, it applied characterization high-electron 500 eV generated due rapid penetration a magnetic field pulse into low-collisionality plasma. Limitations method discussed.
