High-resolution measurement, line identification, and spectral modeling of the KΒ spectrum of heliumlike argon emitted by a laser-produced plasma using a gas-puff target

We present an analysis of the spectrum of satellite transitions to the He-{B} line in Ar XVII. High-resolution measurements of the spectra from laser-heated Ar-gas-puff targets are made with spectral resolution of 10 000 and spatial resolution of better than 50 {μ}m. These are compared with tokamak measurements. Several different lines are identified in the spectra and the spectral analysis is used to determine the plasma parameters in the gas-puff laser-produced plasma. The data complement those from tokamak measurements to provide more complete information on the satellite spectra.
