The feedback control system is restrained plasma vertical displacement on EAST. Fast control power supply excites active feedback coils, which produces magnetic field to control plasma's displacement. To meet the requirement of large current and fast response, multi-inverters in parallel is presented. The validity of proposed scheme has been confirmed by experiments, the active feedback system can reach design demand.

By assuming the ion sphere model, the self-consistent field method for the Poisson-Boltzmann equation and the Dirac equation is used to calculate the energy levels of He-like titanium immersed in hot and dense plasmas. Consequently, the spectral shifts of the intercombination line and the resonance line and the shifts of the exchange energy of He-like titanium in hot and dense plasmas are studied. The results show that the two electronic dipole transitions red shift nearly linearly with the increase of plasma electron density. The formula of the linear relationship is found. The results may be useful in developing the new method of dense plasma diagnosis.
