The magnetic confinement is essentially the same as Jarboe's, relying on spheromaks to contain the plasma.
This intermediate density space falls outside of the major research programs in magnetic confinement and inertial confinement fusion, and represents a high risk, high reward opportunity to identify new pathways to fusion power that may offer relatively inexpensive development cycles.
Magnetic confinement fusion uses magnetic fields to trap the fuel in a magnetic 'bottle,' and inertial confinement fusion heats the surface of the fuel pellet until it blows off in a way that causes the remaining pellet to implode.
The plasma conducts electricity and responds to magnetic fields, motivating a magnetic confinement approach to nuclear fusion.
Construction standards are being developed for magnetic confinement fusion energy devices and high-temperature reactors, and in-service inspection standards are being developed for both gas-cooled and liquid-metal-cooled nuclear power plants.
This work reviews the science of nuclear fusion from the development of the basic scientific ideas concerning the role of fusion in the Sun and other stars to the current progress towards achieving human-controlled fusion energy, covering both the magnetic confinement approach towards insulating hot nuclear fuel with magnetic fields and the newer inertial confinement approach that seeks to capture the fusion energy before the hot fuel has had a chance to expand.
Two of the papers in this collection review modeling approaches to turbulent mixing and void drift in sub-channel analysis and the history of magnetic confinement fusion power plant conceptual designs.
The three CAS labs will include the National Laboratory of Magnetic Confinement and Nuclear Fusion, the National Laboratory of Clean Energy, and the National Laboratory of Protein Science.
There are at present several Ultracold neutron (UCN) experiments that seek to measure the neutron lifetime using magnetic confinement techniques (see these proceedings).
But no one has been able to scrutinize an extragalactic jet with enough detail to see any evidence for magnetic confinement.
Conveniently, again, for the purpose of remote imaging, a natural process constantly converts a few percent of energetic atoms to neutral atoms that are released from their magnetic confinement to travel along line-of-sight paths to a remote imager.
However, most civilian energy projects have focused on magnetic confinement techniques, which use large-sized plasmas and longer time periods to create fusion reactions.
