Large improvements in spheromak parameters and new understanding have been obtained from the CTX experiment at Los Alamos (Phys. Rev. Lett. {bold 51}, 39 (1983); {bold 61}, 2457 (1988)). In one experiment the global energy confinement time has been increased an order of magnitude over previous experiments to 0.2 msec and the magnetic-energy decay time increased to 2 msec. These results were achieved in a decaying spheromak by reducing the helicity dissipation in the edge. In another smaller spheromak, record electron temperatures ({similar to}400 eV) and record magnetic field strengths ({similar to}30 kG) have been obtained.
