Abstract :
Summary form only given, as follows. We will report recent results from the Sustained Spheromak Physics Experiment (SSPX) in which we measure peak electron temperatures greater than 300eV in driven spheromak discharges. The SSPX spheromak plasma (0.31m major radius, 0.13m minor radius) is driven for up to 4msec by a DC coaxial source (a Marshall gun), which is powered by a 2MJ capacitor bank. The plasma is contained inside a tungsten-coated copper flux conserver which maintains stability against global tilting modes.
