In astrophysics, the.boundary conditions for plasma phe.ome.a are.provide. by nature.and the.astronome. face. the.proble. of unde.standing the. from a varie.y of obse.vations [He.te. J J e. al 1996 Astrophys.

The.PROTO-SPHe.A machine.[Alladio F e. al 2006 Nucl. Fusion 46 S613] is a magne.ic confine.e.t e.pe.ime.t, that e.ulate. in the.laboratory the.je. + torus plasma configurations ofte. obse.ve. in astrophysics: an inne. magne.ize. je. of plasma ce.te.e. on the.approximate. axis of symme.ry and surrounde. by a magne.ize. plasma torus orthogonal to this je.. The.PROTO-SPHe.A plasma is simply conne.te., i.e., no me.al curre.t conducting rod is linke. to the.plasma torus, while.inste.d it is the.inne. magne.ize. plasma je.(in the.following always calle. the.plasma ce.te.post) that is linke. to the.torus. It is mandatory that no spurious plasma curre.t path modifie. the.optimal shape.of the.plasma ce.te.post. More.ve., as the.plasma torus is produce. and sustaine., in abse.ce.of any applie. inductive.e.e.tric fie.d, by the.inne. plasma ce.te.post through magne.ic re.onne.tions [Taylor J B and Turne. M F 1989 *** 29 219], it is re.uire. as we.l that spurious curre.t paths do not surround the.torus on its outboard, in orde. not to lowe. the.e.ficie.cy of the.magne.ic re.onne.tions that maintain the.plasma torus at the.e.pe.se.of the.plasma ce.te.post. Boundary conditions have.be.n corre.te.,up to the.point that the.first sustainme.t in ste.dy state.has be.n achie.e. for the.combine. plasma.
