12-kW advanced electric propulsion system hall current thruster qualification and production status Open
Initial developments by the National Aeronautics and Space Administration (NASA) of a 12-kW-class Hall thruster began with maturation of the Hall Effect Rocket with Magnetic Shielding, which was then transitioned to industry via the Advanc…
On Robust $β$-Spectra Shape Parameter Extraction Open
Experimental extraction of $β$-shape functions, C(W), is challenging. Comparing different experimental $β$-shapes to each other and to those predicted by theory in a consistent manner is difficult. This difficulty is compounded when differ…

Inferring the scrape-off layer heat flux width in a divertor with a low degree of axisymmetry Open
Plasma facing components (PFCs) in the next generation of tokamak devices will operate in challenging environments, with heat loads predicted to exceed 10 MWm$^{-2}$. The magnitude of these heat loads is set by the width of the channel, th…

Results from the CDX-U Lithium Wall and NSTX Lithium Pallet Injection and Evaporation Experiments Open
CDX-U has been operated with the vacuum vessel wall and limiter surfaces nearly completely coated with lithium, producing dramatic improvements to plasma performance. Discharges achieved global energy confinement times up to 6 ms, exceedin…
RECONSTRUCTION AND RESTORATION OF HISTORICAL MONUMENTS: INTERNATIONAL EXPERIENCE Open
Introduction: In addition to recognizing and taking into account the vital need for the maintenance and repair of historical structures, this study will focus on their inherent design potential at the intersection of the new and the old. P…
Electromagnetic Moments and Emerging Nuclear Collectivity near Z=50 Open
The isotope 132Sn appears to be one of the most robust examples of a double shell closure. As a result, the surrounding region provides excellent opportunities to test shell-model predictions and investigate the emergence of collectivity a…
