Description

The vertical position of the JET plasma is unstable without feedback stabilisation. The growth rate can reach 200s-1 for strongly elongated plasmas (b/a ≅ 2). A failure of the stabilisation at large plasma current (7MA) can cause damage to the vessel due to large vertical forces. A dual system which continues the stabilisation even in case of faults in the measurement system or in the conditioning electronics is needed for high reliability. A significant simplification in the control was also achieved by avoiding magnetic signals integration
