Sustained Spheromak Physics Experiment

The Sustained Spheromak Physics Experiment (SSPX) is a program at Lawrence Livermore National Laboratory in the United States established to investigate spheromak plasma.

A spheromak device produces a plasma in magnetohydrodynamic equilibrium mainly through self-induced plasma currents, as opposed to a tokamak device which depends on large externally generated magnetic fields. The series of experiments examines the potential for a spheromak device to contain fusion fuel. According to a 1999 abstract,
 * The Sustained Spheromak Physics Experiment, SSPX, will study spheromak physics with particular attention to energy confinement and magnetic fluctuations in a spheromak sustained by electrostatic helicity injection.
