Abstract

A spectroscopic diagnostic method, to measure electron temperature of radiation-heated CH foam on Shenguang II laser facility, is described. A tracer layer of aluminum was embedded in the middle of the CH foam and a point-projection method used in the opacity experiment was induced to measure the transmission spectrum of the embedded A1 foil. The electron temperature, of about 80 eV, was deduced through a comparison of the experimental absorption spectrum with the calculated one with a detailed level accounting opacity code. The results of hydrodynamic simulation show that it's reasonable to determine the CH foam temperature by measuring the embedded Al absorption spectrum. Thus, the electron temperature of radiation-heated CH foam was obtained.

Abstract

An experimental measurement of radiatively heated iron plasma transmission spectra was performed on Shenguang II laser facility. In the measurement, the self-emission spectrum, the backlighting spectrum, and the absorption spectrum were imaged with a flat filed grating and recorded on a gated micro channel plate detector to obtain the time-resolved transmission spectra in the range 10–20 A (approximately 0.6–1.3keV). Experimental results are compared with the calculation results of an unsolved transition array (UTA) code. The time-dependent relative shift in the positions of the 2p−3d transmission array is interpreted in terms of the plasma temperature variations.

Abstract

X-ray spectra of H-like and He-like aluminum ions from aluminum buried in CH layers irradiated with 30 fs, 200 TW laser are measured. The electron temperature and density are derived from line ratios of the He-α resonance line to its satellite lines. Typical temperatures of 490–646eV and electron densities up to 7 × 1020 cm−3 are obtained. The results show that the electron density increases and temperature decreases with the increasing CH thickness.

Abstract

The KLL dielectronic recombination processes of highly charged He-like to C-like Kr ions have been studied experimentally. The measurement was performed on the newly developed Shanghai electron beam ion trap (Shanghai-EBIT) facility. Characteristic x-rays from both dielectronic recombination and radiative recombination are detected as the electron beam energy is scanned through the resonances. The KLL resonant strengths obtained are 5.41 × 10−19, 4.33 × 10−19, 3.59 × 10−19, 2.05 × 10−19 and 0.98 × 10−19 cm2 eV for He-like to C-like Kr ions, respectively.
