Description

Beam driven stable equilibria for a conceptual reactor, Demo-CREST, which was designed for early demonstration of electric power generation, has been investigated. Considering current profiles driven by neutral beams, the attainable normalized beta βN with a stabilization wall is about 3.4 with a normal shear (NS). With reversed shear (RS), a higher βN is attainable. The stable equilibria up to 4.0 can be sustained by a couple of On-and Off-axis beams. In the range of 1.9 < βN < 4.0, power of each beam does not exceed the power in the case of βN=1.9 which is the base design point of Demo-CREST. In the case of RS operation with βN=4.0,the density ratio to the Greenwald limit can be maintain at about unity if high temperature operation with Te>20 keV is allowable.
