Turbulent Convection and Anomalous Cross-Field Transport in Mirror Plasmas

Extended possibility of an active control of co-axially nested shear plasma formation due to electron cyclotron heatings

“…Mirror devices (Budker, Mirnov & Ryutov 1971; Pastukhov 1974; Fowler & Logan 1977; Post 1987; Cho et al. 2001; Pastukhov & Chudin 2011) having open ended regions, provided intrinsic advantages in terms of easy control of radial potential or sheared rotation profiles on the basis of axial particle loss control (Pastukhov 1974; Cho et al. 2005 a , 2006, 2008; Pastukhov & Chudin 2011).…”

“…The suppression of turbulence and the associated significant reduction due to cross-field transport of the mirror showed behaviour that was similar to those seen for Low-to-High (L-H) mode transitions in tokamaks. Mirror devices (Budker, Mirnov & Ryutov 1971;Pastukhov 1974;Fowler & Logan 1977;Post 1987;Cho et al 2001;Pastukhov & Chudin 2011) having open ended regions, provided intrinsic advantages in terms of easy control of radial potential or sheared E × B rotation profiles on the basis of axial particle loss control (Pastukhov 1974;Cho et al 2005aCho et al , 2006Cho et al , 2008Pastukhov & Chudin 2011).…”

“…Therefore, these three types of devices essentially showed improvement from the viewpoint of sheared plasma confinement. Each of them, however, had the intrinsic characteristic property of electron or ion confinement (Fujita et al 1997;Kishimoto et al 2000;Diamond et al 2005;Cho et al 2005aCho et al , 2006Takeiri et al 2007;Cho et al 2008;Pastukhov & Chudin 2011).…”
