Book excerpt: The Thomson Scattering Diagnostic on TMX was built to measure the electron temperature in the plug. The design was based on the 2XII system built by Tom Simonen. Substantial improvements were realized over the original design, these include: (1) improved sensitivity, (2) simultaneous multiple position sampling, (3) multiple pulse capability, (4) achromatic imaging, (5) vacuum alignment capability, (6) high reliability, and (7) built in calibration and performance monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: This Thomson scattering diagnostic system is used to measure the electron temperature and density of the east mirror plug of the Tandem Mirror Experiment (TMX) at Lawrence Livermore Laboratory. The measurements are made by firing a high-power ruby laser pulse through the plasma where the electrons then re-radiate a small fraction of the light. Because of the velocity of the electrons, the wavelength of the re-radiated light is Doppler shifted. The width of the Doppler-shifted wavelength spectrum is a measure of the temperature of the electrons in the plasma, and the total amount of re-radiated light is proportional to the electron density.

Available in PDF, EPUB and Kindle. Book excerpt: A two-dimensional Thomson scattering system has been designed for the Advanced Toroidal Facility (ATF), a torsatron experiment at the Oak Ridge National Laboratory (ORNL). The system is a modification of the Thomson scattering system used on the Impurity Study Experiment (ISX-B) tokamak. It will provide measurements of electron temperature (T/sub e/) and density (n/sub e/) at 15 points along a vertical chord. With multiple shots, a T/sub e/ and n/sub e/ map of a toroidal cross section of ATF can be obtained. The horizontal Thomson scattering viewing port is offset by 15° toroidally from the ports through which the vertical laser beam passes. The modifications to the ISX-B Thomson scattering system are either changes required to adapt the system to the ATF device geometry or changes that result in improvements to the original system. This paper deals with the mechanical design aspects of the laser light baffle plates that reduce the amount of extraneous light entering the plasma, the upper and lower vacuum extensions that contain the baffles and attach to the ATF vacuum vessel, the entrance window assembly, the laser dump assembly, the viewing window and shutter assembly, and the alignment target mechanism and drive used to determine the ampping of data points in the plasma cross section.
Download or read book Noncollective X ray Thomson Scattering Diagnostic Development Based on a Titanium Hybrid X pinch X ray Source written by Cad Lewis Hoyt and published by . 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.
