Solid spherical blanket, a~30 cm, made of LiH; it absorbs neutrons, breeds tritium; evaporated material serves as a working fluid Axisymmetric jabot r 1 A transmission line (vacuum, or filled with flibe) A core containing circuitry, switches, and the target proper (nothing of that shown) Fig. 1 Cross-section of an MTF target surrounded by a spherical LiH blanket. The structuee of the target is not shown. The inner surface of a transmission line inside the LiH sphere is coated by a conducting material (e.g., metal Li). The shape of the jabot (made of conical surfaces) is explained in Fig. 2.
The positive voltage is applied to the upper electrode when the jets reach the current-receiving “jabot”; the lowe electrode stays at the ground potential Highly collimated gaseous jets r 1 A currentreceiving “jabot” D~20 cm Supersonic nozzles (an azimuthal array) r 0 The target, with the jabot attached, is dropped to a 3-m radius reaction chamber. The jabot is made of thin (~1mm thick) lithium sheets, it collects the current flowing along the disc-shaped plasma electrodes and directs it to the target. Fig. 2 Schematic of the target dropped into reaction chamber. The scales are distorted for a better visibility. The shape of the jabot is determined by the requirement that the gas and plasma are deflected away from the equatorial plane. The blow-up of the blanket and the target are shown in Fig. 1. Magenta lines show the highly conducting plasma layers formed as a result of a surface breakdown of the gas
