| toroidal current | <radiobiology> Current flowing in the toroidal direction (the long way) around a torus. (As distinct from poloidal currents flowing through the centre of the torus and around to the outside, the short way.) (09 Oct 1997) |
|---|
| advanced toroidal facility | <physics> A large stellarator device developed at Oak Ridge National Lab (ORNL), but now retired. Acronym: ATF (09 Oct 1997) |
|---|---|
| toroidal | <radiobiology> In the shape of a torus, or doughnut. Or: Coordinate indicating which part of the torus a particle is in. (Azimuthal coordinate, toroidal angle, etc.) Or: General term referring to toruses as opposed to other geometries. (for example, tokamaks and stellarators are examples of toroidal devices.) (09 Oct 1997) |
| toroidal beta | <radiobiology> Plasma beta using the toroidal magnetic field, i.e. Plasma pressure divided by toroidal field pressure. See: beta. (09 Oct 1997) |
| toroidal divertor | <radiobiology> Divertor created by extracting toroidal field field lines at some point, forming an external loop outside the torus. Has the disadvantages that it breaks the axial symmetry of the torus, which converts a relatively simple, mostly 2-dimensional geometry to a comples 3-dimensional geometry. For an illustration refer to page 135 of Gross (reference 4). (09 Oct 1997) |
| toroidal field coils | <radiobiology> Coils in a toroidal system, typically wound around the torus in a solenoid-like arrangement, used to generate the toroidal magnetic field. Each turn completely surrounds the plasma. (09 Oct 1997) |
| toroidal flux | <radiobiology> Magnetic field flux in the toroidal direction. See: magnetic fields. (09 Oct 1997) |
| toroidal magnetic cusps | A hybrid confinement scheme operating at high beta. A region of closed toroidal magnetic flux with high-beta plasma is separated by a narrow sheath from the surrounding field, which contains externally produced poloidal components arranged in a toroidal line-cusp configuration. Plasma migrating to the outer sheath is temporarily mirror-confined before being removed in a divertor system. (09 Oct 1997) |
| action current | An electrical current induced in muscle fibres when they are effectively stimulated; normally it is followed by contraction. (05 Mar 2000) |
| alternating current | Electrical current which alternates direction periodically. (For instance, household electric current is AC alternating at 60 oscillations/sec (60 Hertz) in the United States, and 50 Hertz in many other countries.) Acronym: AC (09 Oct 1997) |
| anodal current | A current produced in tissues under the anode when the circuit is closed. (05 Mar 2000) |
| ascending current | The direction of current flow in a nerve when the anode is placed peripheral to the cathode, in contrast to descending current; the convention used is that current flows from positive to negative. Synonym: centripetal current. (05 Mar 2000) |
| axial current | The central rapidly moving portion of the bloodstream in an artery. (05 Mar 2000) |
| bootstrap current | <radiobiology> Currents driven in toroidal devices by neo-classical diffusion. They may amount to a substantial fraction of the net current in a tokamak reactor, thus lengthening the pulse time or decreasing the power needed for current drive. (09 Oct 1997) |
| calcium current | Inflow of calcium ions through specific calcium channels. Critically important in release of transmitter substance from presynaptic terminals. (18 Nov 1997) |
| galvanic current | See: direct current, galvanism. (05 Mar 2000) |
