Fast digital link for a tokamak current source control

Abstract

The need for real-time plasma position control on the ISTTOK tokamak led to the development of two similar 240 A:500 kA/s fast power supplies, for the vertical and horizontal magnetic equilibrium fields. This paper presents the design, the digital link, the modeling and operation of the vertical B-field power supply. It consists of a digital hard real-time… (More)
