Background Fenestrated endovascular aneurysm repair (FEVAR) is increasingly being used for juxtarenal aortic aneurysms. The aim of this study was to review long‐term results and assess the importance of changing stent‐graft design on outcomes. Me

In this chapter we discuss the various diagnostic techniques in which active spectroscopy plays a role. The use of an injected neutral beam - either a dedicated diagnostic beam or the main heating beams - to localize and enhance the spectroscopic mea

Neutron images have been successfully recorded with “gel-type bubble detectors.” 14 MeV fusion neutrons emitted from laser-irradiated inertial confinement fusion targets formed coded images in proof-of-principle experiments conducted at the OMEGA

The results of proof-of-principle neutron imaging experiments using bubble detectors are reported. Bubble detectors, which detect neutrons with a spatial resolution as small as 5 μ, were used to image the neutrons from laser-driven compressed deuter

New phase space mapping and uncertainty analysis of energetic ion loss data in the DIII-D tokamak provides experimental results that serve as valuable constraints in first-principles simulations of energetic ion transport. Beam ion losses are measure

Energy and pitch angle resolved measurements of escaping neutral beam ions (E approximate to 80 keV) have been made during DIII-D L-mode discharges with applied, slowly rotating, n = 2 magnetic perturbations. Data from separate scintillator detectors

Enhanced localized energetic ion losses resulting from first-orbit linear and non-linear interactions with Alfvén eigenmodes in DIII-D. Physics of Plasmas, 21(8). doi: 10.1063/1.4891442. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/27f6p3mg
Two key insights into interactions between Alfvén eigenmodes (AEs) and energetic particles in the plasma core are gained from measurements and modeling of first-orbit beam-ion loss in DIII-D. First, the neutral beam-ion first-orbit losses are enhanc
