Impermeable plasma is a type of thermal plasma which acts like an impermeable solid with respect to gas or cold plasma and can be physically pushed. Interaction of cold gas and thermal plasma was briefly studied by a group led by Hannes Alfvén in 1960s and 1970s for its possible applications in insulation of fusion plasma from the reactor ...
The Wendelstein 7-X device is based on a five-field-period Helias configuration.It is mainly a toroid, consisting of 50 non-planar and 20 planar superconducting magnetic coils, 3.5 m high, which induce a magnetic field that prevents the plasma from colliding with the reactor walls.
A field-reversed configuration (FRC) is a type of plasma device studied as a means of producing nuclear fusion. It confines a plasma on closed magnetic field lines without a central penetration. [1] [2] In an FRC, the plasma has the form of a self-stable torus, similar to a smoke ring.
Plasma is an ionized gas that conducts electricity. [16] In bulk, it is modeled using magnetohydrodynamics, which is a combination of the Navier–Stokes equations governing fluids and Maxwell's equations governing how magnetic and electric fields behave. [17] Fusion exploits several plasma properties, including:
Nuclear pulse propulsion or external pulsed plasma propulsion is a hypothetical method of spacecraft propulsion that uses nuclear explosions for thrust. [1] It originated as Project Orion with support from DARPA , after a suggestion by Stanislaw Ulam in 1947. [ 2 ]
where C 0 is the collimation factor (what fraction of the explosion plasma debris will actually hit the impulse absorber plate when a pulse unit explodes), V e is the nuclear pulse unit plasma debris velocity, and g n is the standard acceleration of gravity (9.81 m/s 2; this factor is not necessary if I sp is measured in N·s/kg or m/s). A ...
Nuclear energy, with its unmatched ability to deliver 24/7 power, fits the bill perfectly," Kathryn Huff, an associate professor of nuclear, plasma, and radiological engineering at the University ...
Project Orion in the 1960s envisioned the use of nuclear shaped charges for propulsion. The nuclear explosion would turn a tungsten plate into a jet of plasma that would then hit the drive pusher plate. About 85% of the bomb's energy could be directed into the target as plasma, albeit with a very wide cone angle of 22.5 degrees.
