1422545 Fusion of nuclei B C MAGLICH 3 April 1973 [25 April 1972] 15842/73 Heading G6P A nuclear fusion reactor (termed a " migma reactor ") embodies coils arranged to produce a magnetic field which has decreasing strength radially from the axis of the reactor and increasing strength axially. from the mid-plane of the reactor so as to induce precession of, and exert radial and axial focusing forces on, likecharged ions which are injected to the centre of symmetry of the field thereby to cause ion collisions producing nuclear fusion. Following an extensive discussion of the theory behind the operation of the reactor and the types of reactions effected, a practical construction is described as summarized below. A " migma cell " (single cell of a " migma reactor ") (Fig. 106) comprises aluminium foil cylinders 201-206 stretched on copper mesh and an outer, copper cylinder 207 all supported from an alumina ceramic plate 300 and connected to HT connectors 301-307. Pairs of coils la, 2a (more particularly described with reference to Fig. 1c, not shown) are arranged inside cylinder 201 and are cooled to render them superconductive; leads 9, 10 supply the coils. An enclosing jacket 408 has a refrigerant circulated therethrough and the interior of the jacket is evacuated. A 2À2 MeV deuteron beam 500 is injected and focused by quadrupole lenses 412 to produce a migma (organized mixture of precessing selfcolliding orbits of positively charged ions) in the reaction region between the coils 1a, 1b. Nuclei leaving this region are collected by the cylinders 201-207 for the purpose of electricity generation. The " migma reactor" " (Figs. 11a, 11b). comprises rows and columns of " migma cells " as previously described. The cylinders are replaced by flat plates. Any deuteron which enters the escape cone of one " migma cell " is trapped in an adjacent " migma cell " and so follows a trajectory 999. Each column of cells is filled in succession by a two-dimensional scanning technique. |
