Abstract
A new type fusion reactor is proposed. The reactor consists of four identical mirror machines each of which is equipped with a plasma-neutral particle converter. The mirror machine is asymmetric so that the magnetic field of the one end of the machine is larger than that of the other end. So, the plasma trapped in the mirror machine is lost through the end of weaker field. The plasma flux lost through the end enters the plasma-neutral particle converter where ions of the plasma aquire surplus energy and, then, change into neutral particles by charge exchange collision in a gas chamber. The neutral particle beam from the plasma-neutral beam converter is injected into the next mirror machine through the entrance port attached at the side of the machine. The ion confinement time of the reactor is expected to be several times longer than that of each mirror machine composing the reactor. Since the energy which is necessary to compensate the energy loss from the reactor is supplied to the ions during their fleight in the plasma-neutral particle converter, it is not necessary to equip the reactor with any neutral beam injector.
