Work on creating a thermonuclear fusion reactor, which began more than half a century ago, has not yet led to the development of a continuous reactor design. The reason for this is the orientation of all teams developing reactors to use one chamber where the reaction occurs. With the arrangement, no materials or cooling schemes can withstand the super-solar temperatures required to achieve fusion. An engineering solution to the problem has been proposed: the use of several synthesis chambers operating alternately. Some details of this reactor layout are considered.
