Estimations of Mo X-pinch plasma parameters on QiangGuang-1 facility by L-shell spectral analyses

Abstract

Plasma parameters of molybdenum (Mo) X-pinches on the 1-MA QiangGuang-1 facility were estimated by L-shell spectral analysis. X-ray radiation from X-pinches had a pulsed width of 1 ns, and its spectra in 2-3 keV were measured with a time-integrated X-ray spectrometer. Relative intensities of spectral features were derived by correcting for the spectral sensitivity of the spectrometer. With an open source, atomic code FAC (flexible atomic code), ion structures, and various atomic radiativecollisional rates for O-, F-, Ne-, Na-, Mg-, and Al-like ionization stages were calculated, and synthetic spectra were constructed at given plasma parameters. By fitting the measured spectra with the modeled, Mo X-pinch plasmas on the QiangGuang-1 facility had an electron density of about 10 21 cm À3 and the electron temperature of about 1.2 keV.

“…The reliability of the obtained values of the plasma parameters was also confirmed by the analysis of the dynamics of level excitation. The L spectra were usually used to determine the plasma parameters in experiments with Мо Х-pinches [91,92,94,96,97,101,102]. However, spectra recorded with a high time resolution were thoroughly analyzed only in [91].…”

Phenolics and polysaccharides in major tropical fruits: chemical compositions, analytical methods and bioactivities

“…The polysaccharides from both fruit pulps exhibit good anti-lipid peroxidation function. 24,25 Proanthocyanidins naturally occur in many fruits, and possess antioxidant, anticarcinogenic, antimutagenic, antiviral, antibacterial, anti-inflammatory and antiallergic activities. [26][27][28][29] Some polysaccharides isolated from fruits also exhibit various important biological activities, such as antioxidant, antitumor, immunomodulatory and anti-inflammatory effects.…”

Solubilization of poorly water‐soluble bioactive molecules in neutral aqueous media by complexation with renatured β‐1,3‐1,6‐glucan nanoparticles

“…r‐Glucan showed a larger red shift at lower NaOH concentrations compared with that of t‐glucan. Congo red is believed to interact with β‐1,3‐glucans as a supramolecular assembled structure, with the degree of the λ max shift affected by the aggregate structure. The change of triplex structure on the r‐glucan surface upon the formation of r‐glucan from t‐glucan was speculated to affect the assembled structure of Congo red.…”
