High-resolution measurement, line identification, and spectral modeling of the K{beta} 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-{beta} line in ArXVII. High-resolution measurements of the spectra from laser-heated Ar-gas-puff targets are made with spectral resolution of 10000 and spatial resolution of better than 50 {mu}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. {copyright} {ital 1997} {ital The American Physical Society}
