The particles are scattered out of the loss cone and are trapped. Fraction of incident radiant energy which is reflected by a given surface. Equivalent for Man. The quality factor depends on the type of radiation involved and is used to scale the radiation dose based on the relative harmfulness of different sorts of radiation, compared to ordinary X-rays. See also radiation dose, roentgen, sievert, rad, gray.
Resistance is determined by resistivity and geometrical factors.
Typically much larger than reserves. It is characterized by a magnetic field mostly generated by the plasma itself, with toroidal and poloidal components of comparable intensities, in contrast with the Tokamak where most of the field is toroidal and externally applied. The name of the configuration is given by the fact that the toroidal component of the magnetic field changes sign in the outer region of the plasma. The main attractivness of the Reversed Field Pinch is that, according to presently established scalings, it could reach ignition without the need of auxiliary heating. Named after Wilhelm Roentgen.
