Toroidal field ripple effects in TNS design

PDF Version Also Available for Download.

Description

In the design of TNS, the choice of the number of TF coils has been made on the basis of trade-off studies among the plasma physics considerations and engineering design requirements. The theory of the magnetic field ripple effects has been studied to include the effects of noncircular cross sections such as those encountered in high-beta equilibria. A computer simulation model (RIPPLE) was developed to examine the field ripple effects on plasma transport and scaling. The magnetic field computer program BOVAL was used to calculate the magnetic field due to current flowing in a noncircular coil of finite rectangular cross ... continued below

The theory of the magnetic field ripple effects has been studied to include the effects of noncircular cross sections such as those encountered in high-beta equilibria. A computer simulation model (RIPPLE) was developed to examine the field ripple effects on plasma transport and scaling. The magnetic field computer program BOVAL was used to calculate the magnetic field due to current flowing in a noncircular coil of finite rectangular cross section. The number of toroidal field (TF) coils is then determined by calculating the maximum magnetic field ripple that can be tolerated from plasma physics considerations.
