Sustained Spheromak Physics Experiment


Cross section of the SSPX vacuum vessel

The Sustained Spheromak Physics Experiment (SSPX) is a program at Lawrence Livermore National Laboratory in the United States established to investigate spheromak plasma.[1]

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.[2] 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.[3]
