A new concept for fusion reactor device

A new advanced concept for fusion reactor device is suggested. Combining the merits of linear and toroidal configurations as well as the fast and slow process concepts, a fusion reactor consisting of two axisymmetric tandem mirror-like sections and two heliac stellarabor U-bends is considered. Start-up, transition and operating phases are studied. The D-D reactor parameters and stabilities are discussed. The RF and energetic components are only needed for start-up; their production would constitute only a temporary energy drain on the overall reactor economics of this system. Besides, the plugs are needed only at the start-up phase. This also greatly reduces the technical requirements of engineering
