High-power heating of spherical tori by use of magnetic reconnection
Earth, Planets and Space volume 53, pages527–530(2001)
A novel high-power heating experiment of spherical tori (ST) has been developed in the TS-3 reconnection device using magnetic reconnection of merging STs. This method enables us to inject whole magnetic and thermal energies of a colliding ST into a target ST within short reconnection time. The maximum heating power of 15 MW was obtained in our low-field (0.03–0.08 T) and small-scale (R < 0.2 m) merging experiment. This heating energy is provided mostly by anomalous ion heating effect of magnetic reconnection. The ion heating energy and the merging speed increases with decreasing the q-value (B t component) of the ST. This heating effect causes the β-values of STs to increase by factor 2–3.
