A major goal of the spherical tokamak (ST) research program is accessing a state of low internal inductance li, high elongation κ, and high toroidal and normalized beta ( βt and βN) without solenoidal current drive. Local helicity injection (LHI)

Recent Pegasus experiments are developing solenoid-free startup techniques using point-source magnetic helicity injection. These plasma sources, called “plasma guns”, ionize a stream of gas in a discharge channel, and bias this channel with respe

Large stable values of normalized current IN are achievable in spherical tori due to the large gradient of the toroidal field across the plasma. This allows access to high Troyon beta limits. Values of IN > 12 MA/m-T are expected to be stable to idea

Initial experiments in the Pegasus ST exhibited an operational limit of I p ∼ I tf at A ∼ 1.15. With new power supplies, discharge control has greatly increased. Equilibria and stability modeling of the high I p/I tf regime has produced stable eq

The Pegasus Toroidal Experiment was developed to explore the physics limits of plasma operation as the aspect ratio (A) approaches unity. Initial experiments on the device found that access to high normalized current and toroidal beta was limited by
