Аннотация:
Regular oscillations have been detected under a limited range of conditions in a 12-in. bore torus. The electric and magnetic fields associated with these have been investigated and indicate a helical notch of reduced density travelling on the pinched current channel with a uniform velocity. A possible explanation of the phenomenon is given. The oscillation is considered to be growing as a sound wave in a partially-ionized medium. The mode is cited as an example of a pinched discharge with poor confinement.
