Density measurements using coherence imaging spectroscopy based on Stark broadening.
A coherence imaging camera has been set up at Pilot-PSI. The system is to be used for imaging the plasma density through the Stark effect broadening of the H(γ) line. Local density values are then obtained by the Abel inversion of the measured interferometric fringe contrast. This report will present the instrument setup and proof-of-principle demonstration. The inverted spatial electron densit...
متن کاملCharacterization of Expanding Laser Plasma Produced by Laser Ablation
This work is devoted to characterizing the plasma produced by nanosecond laser ablation. The expanding plasma was generated by the interaction of a home made XeCl excimer laser with a Cu target. The time-of-flight method was utilized as diagnostic tool of the plasma charged particles. By this method, in fact, we were able to measure the ion and electron currents, the charge-states and the energ...
متن کاملHydrogen Stark Broadening Calculations With
The unified theory has been generalized for the case of upper and lower state interaction by introducing a more compact tetradic notation. The general result is then applied to the Stark broadening of h>drogen. The thermal average of the time development operator for upper and lower state interaction is presented. Except for the time ordering it contains the effect of finite interaction time be...
متن کاملDirect Comparison of Electron Density Measurements in Laser-created Plasmas Using Stark Broadening and Satellite Line Intensities
Spectral line profiles, broadened mostly by Stark effects from electric fields produced by charge particles, and dielectronic satellite line intensities have recently been used for determining electron densities in the dense region of lasercreated plasmas [1-3]. We present here a direct comparison of electron density measurements in the conduction region of laser created plasmas on a plane targ...
متن کاملIon Velocity Measurements and Characterization of a Laser Induced Plasma
Ions emitted by a laser produced plasma were detected with a Faraday cup. It was determined that the majority of the ion velocities fell within the range of 50 to 250 km/s. A beam of ions was created by passing the plasma through a 2mm iris to create a beam with a width was about 1cm. To determine the ion species present in the plasma and the velocity distribution, the ions were passed through ...
