Itami Conceptual Design Description of a CT Fueler for JT-60U(2000) Pulsed High Density Fusion Experiment (PHD) Examples DeviceĬompact Toroid Injection Experiment (CTIX) High velocity jets of controllable density and temperature allow astrophysical phenomena such as solar wind, galactic jets, solar events and astrophysical plasma to be partially simulated in the laboratory and measured directly, in addition to astronomic and satellite observations. Īrrays of plasma railguns could be used to create pulsed implosions of ~1 Megabar peak pressure, allowing more access to chart this opening area of plasma physics. Plasma railguns are being evaluated as a possible method of implosion linear formation for fusion. Magneto-inertial fusion seeks to implode a magnetized D-T fusion target using a spherically symmetric, collapsing, conducting liner. Plasma rail guns are being evaluated for applications in magnetic confinement fusion for disruption mitigation and tokamak refueling. Accelerator electrode geometry and materials are also open areas of research.Ĭontrolled jets from plasma rail guns can have peak densities in the 10 13 to 10 16 particles/m 3 range, and velocities from 5 to 200 km/s, depending on device design configuration and operating parameters, and the upper limits may be higher. Since the driver current through the armature is also moving through and normal to a self-generated magnetic field, the armature particles experience a Lorentz force, accelerating them down the length of the gun. However, techniques including exploding foils, gas cell burst disk injection, neutral gas injection via fast gas valve, and plasma capillary injection have been employed.Īfter armature formation, the plasmoid is then accelerated down the length of the railgun by a current pulse driven through one electrode, through the armature, and out the other electrode, creating a large magnetic field behind the armature. As plasma railguns are an open area of research, the method of armature formation varies. In either design, a plasma armature is formed at the breech. Coaxial accelerators use various techniques to mitigate this instability. This is an instability in which the magnetic pressure front can out-run or "blow-by" the plasma armature due to the radial dependence of acceleration current density, drastically reducing device efficiency. ![]() Coaxial accelerators require insulators only at the breech, but the plasma armature in that case is subject to the "blow-by" instability. Additionally, a complex triple joint seal may exist at the breech of the bore, which can often pose an extreme engineering challenge. Linear plasma railguns place extreme demands on their insulators, as they must be an electrically insulating, plasma-facing vacuum component which can withstand both thermal and acoustic shocks. Coaxial railguns accelerate toroidal plasma armatures using a hollow outer conductor and a central, concentric, inner conductor. Linear railguns consist of two flat plate electrodes separated by insulating spacers and accelerate sheet armatures. Plasma railguns appear in two principal topologies, linear and coaxial.
