Meetings/Workshops on Plasma and Gas-discharge Physics, Nuclear Fusion in the United States (USA)

The ultimate goal of the US-EU Transport Task Force (TTF) is to develop a physics-based understanding of particle, momentum and heat transport in magnetic fusion devices. This understanding should be of sufficient depth that it allows the development of predictive models of plasma transport that can be validated against experiment, and then used to simulate the future performance of burning plasmas in ITER, and next-step fusion energy reactors.

The 2020 U.S. TTF Workshop will be co-located with the 2020 Sherwood Fusion Theory Conference and coordinated with the 2020 Asia-Pacific Transport Working Group.

Scientific Computing ,    Modeling and Simulation

High-temperature plasma diagnostics and instrumentation is a growingly interdisciplinary field. The hardware couplings to software and data science are stronger than ever, driven in part by some of the most challenging problems in the laboratory and natural plasma environment. This biennial conference extends a long tradition in plasma instrumentation, provides an international forum to showcase the latest advances and new possibilities that include but are not limited to plasma instrumentation hardware, software, and data science. A broad spectrum of contributions are expected with impact on magnetic confinement fusion, inertial confinement fusion, space plasmas, astrophysics, industrial applications, and data science. The conference contributions will be peer-reviewed before archiving in a special issue of Review of Scientific Instruments.

Metrology and Instrumentation,    Atomic and Molecular Physics

ASC is the foremost gathering point for the electronics, large scale, and materials fields within the applied superconductivity community. We expect program content to include original work in digital electronics, quantum information, astronomy, accelerators, fusion, energy, transportation, medicine, conductors, and properties and testing. The 2020 theme, “Bringing Horizons into Clear View,” acknowledges the excitement of superconductivity and the predictions made in the past, the long journey many applications have taken to come to fruition, and the promising opportunities yet to come.

A fascinating and surprising phenomenon that can occur in fluid and plasma turbulence is the spontaneous formation of arrays of layers in which material properties such as density adopt a so-called “staircase” structure. The most striking examples are potential vorticity staircases in planetary atmospheres, and thermohaline staircases in the oceans. Theoretical considerations suggest that layering also plays an important role in stellar interiors (particularly through various double-diffusive processes) and in fusion confinement devices (the so-called E x B staircase). Understanding the phenomenon of layering is, therefore, not only of intrinsic scientific interest (e.g., is there a common thread to layering in these very different contexts?), but is also crucial for an accurate description of turbulent transport in, for example, models of large-scale ocean flow, the evolution of stellar interiors and confinement in tokamaks.
