  • Here, a Particle X-ray Temporal Diagnostic (PXTD) has been implemented on OMEGA for simultaneous time-resolved measurements of several nuclear products as well as the x-ray continuum produced in High Energy Density Plasmas and Inertial Confinement Fusion implosions. The PXTD removes systematic timing uncertainties typically introduced by using multiple instruments, and it has been used to measure DD, DT, D 3He, and T 3He reaction histories and the emission history of the x-ray core continuum with relative timing uncertainties within ±10-20 ps. This enables, for the first time, accurate and simultaneous measurements of the x-ray emission histories, nuclear reaction histories, theirmore » time differences, and measurements of T i(t) and T e(t) from which an assessment of multiple-ion-fluid effects, kinetic effects during the shock-burn phase, and ion-electron equilibration rates can be made.« less

  • The complementary techniques of ion microtomography (IMT) and particle-induced x-ray emission (PIXE) are used to provide micro-characterization of inertial confinement fusion (ICF) targets for density uniformity, sphericity, and trace element spatial distributions. ICF target quality control in the laser fusion program is important to ensure that the energy deposition from the lasers results in uniform compression and minimization of Taylor-Rayleigh instabilities. We obtain 1% density determinations using IMT with spatial resolution approaching two microns. Utilizing PIXE, we can map out dopant and impurity distributions with elemental detection sensitivities on the order of a few ppm. We present examples of IMTmore » and PIXE analyses performed on several ICF targets.« less
