Plasma Conditions for Optimum Gain in Resonant Photoexcitation of Strontium Neon-like Ions by Aluminium Radiation
نویسندگان
چکیده
Resonant photoexcitation of strontium neon-like ions by the radiation of aluminium hydrogen-like ions is studied theoretically and experimentally in laser-created plasmas. X-ray and X W spectroscopy are used as tools to define plasma conditions where photo-pumping is efficient. The design of targets is completed by ablation studies of strontium layers under various experimental conditions. Absorption spectroscopy in a two plasma experiment demonstrates the potential usefulness of quasi-resonant photoexcitation in neon-like X-ray amplifiers.

X-ray Laser Research at Palaiseau
We present the soft X-ray laser experiments performed at Greco "Interaction Laser-Matisre" (Palaiseau). They are mainly concerned with Lithium-like ions of aluminum in plasmas produced by 1.06v Nd-laser. We describe the experimental set-up which performs time-dependent gain measurements. We report results showing a gain-length product of 2 2.5 for the 3d 5f line at 105.7 A . Comparison is made ...
متن کاملFLUORESCENCE AND SMALL-SIGNAL GAIN AT 2177 AND 2163 Å IN CIII BY RESONANT PHOTOEXCITATION WITH 310 Å, MnVI LINE RADIATION
Line radiation at 310 A from a laser-produced Mn plasma was used to resonantly photoexcite the 2s IS 4p Ip0 transition in CIII ions in a vacuum-arc discharge. Enhanced fluorescence, up to a factor of 180, was observed on the 4p-3d line at 2177 A. Enhanced fluorescence was also observed on other 4-3 lines in CIII, because the photoexcited 4p population is collisionally redistributed among all th...

In this research, the zeolite sodalite, as an inorganic ion exchange material, was chemically produced in the template-free synthesis and evaluated in order to facilitate the sorption of strontium ions from aqueous solutions in batch operations onto acid treated zeolite with dilute H2SO4 solutions. The following indicates what the batch experiments included: a sorbent amount of 0.25 g in 100 mL...

A simple complexometric method for stepwise determination of lanthanum, strontium and manganese in Lanthanum-Strontium-Manganate (LSM) has been worked out. The method involves joint titration of the elements with EDTA at pH 10.0 followed by selective precipitation of strontium as sulphate from a homogenous solution involving displacement reaction between EDTA complex of strontium and ZnSO4. The...

This theoretical study examines the characteristics of a surface wave driven plasma monopole antenna using finite difference time domain method (FDTD) as well as commercial full wave simulator. The results show that the full wave simulator can be considered as an acceptable tool in simulation of a plasma antenna. Input impedance, radiation pattern, gain, efficiency and radar cross section of pl...
