Doublet tokamak devices: TNS to demo

A series of D-T burning tokamak devices, which range from an ignition test reactor (ITR) for the next step (TNS) to a demonstration power reactor (DPR), have been studied at the General Atomic Company. The conceptualized series of devices have the Doublet plasma shape in common and consequently illustrate a complete and orderly evolution of a reactor system concept, inclusive of all applicable subsystems. The reference design of each device is summarized including an intermediate upgradable ITR design which contains many aspects of an experimental power reactor. Emphasis in these design efforts has been placed on close integration of physics and engineering considerations
