Progress in the SSPX Spheromak

The spheromak, with its simply connected geometry, holds promise as a less expensive fusion reactor. It has reasonably good plasma beta and can be formed and sustained in steady state with a magnetized coaxial plasma gun. The Sustained Spheromak Physics Experiment (SSPX) shown in Fig. 1 was constructed to investigate the key issues of magnetic field generation and energy confinement. In addition to the coaxial gun, nine magnetic field coils are utilized to shape the vacuum magnetic flux. This f… more

A Laser-Based Diagnostic for Tracing Magnetic Field Lines in Spheromks and Other Self-Organized Magnetically Confined Plamas

We are in the process of testing a new technique for measuring the magnetic field-line topology in magnetically confined plasmas. The basic idea behind the FLIRT (Field LIne TRacing) diagnostic is to use a high powerful short pulse laser to launch a burst of energetic ({approx}100keV) electrons from a target passing through the plasma of interest; these electrons then generally follow field lines until they strike a solid surface, where a burst of x-rays is produced and then detected. The field… more
