Abstract :
A new hybrid method and apparatus is presented for poloidal magnetic field measurement, suitable for use in steady-state control of tokamak plasma shape, position, and current. [An invention disclosure has been filed.] It combines two different magnetic field principles (induction and torque) into a single hybrid measurement apparatus, thus in one device providing accurate magnetic field measurement over the entire frequency spectrum from DC to several kilohertz
