Equilibrium and stability of a toroidal screw pinch

Numerical computation of high-beta toroidal diffuse equilibria

“…This letter presents a method of numerical computation for obtaining diffuse equilibrium configurations of the high-beta toroidal plasma with a free boundary. Sample equilibria for various types of the high-beta tokamak [11], the screw pinch with force-free fields [12][13][14], the reversed-field pinch [15,16], the belt pinch [17][18][19][20], and the doubletheta pinch [21,22] are discussed in the next section. The stability problem is not treated here.…”

Toroidal plasma produced by the stabilized double-theta pinch

“…The search for methods of producing and confining a dense, high-temperature plasma has led many workers to study hybrid pinches, which consist of combinations of two different kinds of pinch actions, such as the sheet pinch [1] and the screw pinch [2,3]. As an analogous combination to the sheet pinch, the double-theta pinch, which consists of a combination of the theta pinch and the inverse theta pinch [4,5], has been studied by the authors [6,7].…”
