Tokamak with high‐voltage theta‐pinch

An experimental device is described which is a combination of Tokamak and a high‐voltage theta‐pinch. Eight Blumlein lines charged to a maximum of 100 kV are connected to the Tokamak shell which plays the role of a theta‐pinch coil, besides stabilizing the plasma. A magnetic pulse with a maximum amplitude of 2.1 kG and a duration of 0.75 μsec is provided by discharging the Blumlein lines simultaneously. Heating of ions by the magnetic pulse is observed.
