Vacuum Magnetic Fields in the Toroidal Extrap Device.

摘要

A model of the ring system of the Extrap T1 device is developed. The model is used for calculating the distribution of poloidal flux and the vacuum magnetic field in the device. Numerical data from the model are compared with measurements. Effects of the vacuum vessel resistivity are discussed qualitatively. Measured profiles of the toroidal and the vertical bias magnetic field in the device are presented. Time constants of the vacuum vessel and the ring structure are estimated.
