Available in PDF, EPUB and Kindle. Book excerpt: This work presents one of the most powerful methods of plasma diagnosis in exquisite detail, to guide researchers in the theory and measurement techniques of light scattering in plasmas. Light scattering in plasmas is essential in the research and development of fusion energy, environmental solutions, and electronics.Referred to as the "Bible" by researchers, the work encompasses fusion and industrial applications essential in plasma research. It is the only comprehensive resource specific to the plasma scattering technique. It provides a wide-range of experimental examples and discussion of their principles with worked examples to assist researchers in applying the theory. - Computing techniques for solving basic equations helps researchers compare data to the actual experiment - New material on advances on the experimental side, such as the application of high density plasmas of inertial fusion - Worked out examples of the scattering technique for easier comprehension of theory

Book excerpt: A new profile analysis package for use with the Thomson scattering data on ISX-B has recently been implemented. The primary feature of this package is a weighted least squares fitting of temperature and density data to generate a representative curve, as opposed to the previous hand-fitting technique. The changes will automate the manner in which data are transmitted and manipulated, without affecting the calculational techniques previously used. The computer programs have also been used to estimate the sensitivity of various plasma quantities to the accuracy of the Thomson scattering data.

Available in PDF, EPUB and Kindle. Book excerpt: Thomson scattering is a fundamental diagnostic tool in high-temperature plasma experiments, providing crucial measurements of electron temperature and density profiles. The operation of Thomson scattering diagnostics involves the propagation of an intense radiation beam through an ionized plasma, with the scattered light from free electrons within the plasma being analyzed. The spectral content of this scattered light contains information on the temperature and density of the plasma under observation. In this work, sources of error are derived and deconstructed for a Thomson scattering system, focusing on three key factors that influence measurement uncertainty: the number of primary photoelectrons generated per pulse, the uncertainty arising from the non-ideal nature of the physical detection apparatus, and the analysis routine's ability to converge on a correct solution. Meticulous examination of these error terms has led to a significant redesign of the Thomson Scattering system at the Helically Symmetric eXperiment (HSX). This redesign, aimed at reducing noise susceptibility while increasing system bandwidth and gain, has involved electronic upgrades and the development of a new signal analysis routine. Results from testing are promising, showing that the redesigned detection electronics and analysis routine have significantly decreased measurement errors compared to the previous diagnostic setup. This work goes beyond systematic improvements, focusing on enhancing the quality and content of measured data without increasing the required number of spectral channels, leading to the development of a novel spectral analysis technique, Thomson Scattering Spectral Multiplexing (TSSM). In a standard Thomson scattering diagnostic, scattered light is divided into wide spectral bands by a filter polychromator equipped with three to eight single bandpass filters. TSSM leverages advanced filters with multiple spectral bands to efficiently utilize Thomson scattered spectra. The results of implementing two TSSM filter sets on the HSX Thomson scattering diagnostic show a reduction in measurement uncertainty and an increased range of electron temperature measurements compared to a filter set with an equivalent number of spectral channels. As a result of this work, the Thomson scattering diagnostic on HSX is now performing at a previously thought unachievable level.

This book was released on 2015 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray Thomson scattering (XRTS) is the combination of elastic Raleigh scattering and inelastic Compton scattering observed from high density systems using energetic probe energies at the keV x-ray level. Thermal x-ray probes have historically been created by delivering 1014 [-] 1016 W/cm2 to a mid-Z metal foil such as titanium using kilojoule-class lasers. An XRTS probe source must provide adequate photon numbers within a finite bandwidth in order to resolve the elastic and inelastic scattering features. This thesis argues that the 4.75 keV He[alpha] spectral feature from a titanium hybrid x-pinch x-ray source driven in a pulsed power circuit can satisfy these photon and bandwidth requirements and function as an XRTS probe source. The arguments are supported through xray diode and image plate photometric analysis for the titanium He[alpha] feature. As a proof of principle, scattering signals from cold, static materials have been collected using the hybrid x-pinch as the probe source. Two different experimental scattering arrangements were developed to collect the weak scattered signals from room temperature targets. The hybrid xpinch was driven in the main current path of the Cornell Beam Research Accelerator (COBRA) 1 MA pulsed power driver for both of these arrangements. The first setup, Focused XRTS (FXRTS), used a spherically-bent germanium xray optic to focus the probe photons collected from a titanium hybrid x-pinch approximately 82 cm away, and focused them onto a 20 [MICRO SIGN]m thick aluminum foil scattering target. The FXRTS setup allowed the entire scattering experiment to be spatially removed from the actual source location, thus lowering background signals on the detectors. For the second scattering setup, Direct XRTS (DXRTS), a new spectrometer was designed and built to function inside the main COBRA vacuum chamber. The scattering setup functioned in a more traditional sense by having the scattering target, 125 [MICRO SIGN]m thick graphite, placed approximately 20 mm away from the x-pinch x-ray source. Protection of the optics and background noise shielding for the detectors were design challenges in the spectrometer. For both experimental arrangements, the backscattered radiation was collected using high-efficiency highly annealed pyrolytic graphite (HAPG) optics and focused onto Fuji Biological Analysis Systems - Tritium type (BAS-TR) image plate detectors. The noncollective FXRTS results from aluminum show the importance of the ion-ion correlation factor within the total dynamic structure factor and its strong dependence on scattering angle. The FXRTS results were fit with theoretical scattering spectrums created using an XRTS subroutine included in the SPECT3D spectral code suite. Unfortunately, the noncollective DXRTS results from graphite were mixed with line and continuum radiation from other sources that made detailed analysis impossible.
