This work reports on error field identification and control studies carried out at the Joint European Torus (JET). To identify the n=1 error field source, the novel compass scan method, designed and tested in the DIII-D device (Paz-Soldan C. et al, Nuclear Fusion 62 (2022) 126007), has been applied at JET. This method also yields the correction currents for error field compensation, which have been included in the empirical EF controller. The main outcomes of error field correction includes the spin-up of born locked modes and the ability to explore a lower density regime than otherwise achievable in the 1.8 MA plasma current, 2.1 T toroidal magnetic field Ohmic scenario.

Abstract
This work reports on error field identification and control studies carried out at the Joint European Torus (JET). To identify the n=1 error field source, the novel compass scan method, designed and tested in the DIII-D device (Paz-Soldan C. et al, Nuclear Fusion 62 (2022) 126007), has been applied at JET. This method also yields the correction currents for error field compensation, which have been included in the empirical EF controller. The main outcomes of error field correction includes the spin-up of born locked modes and the ability to explore a lower density regime than otherwise achievable in the 1.8 MA plasma current, 2.1 T toroidal magnetic field Ohmic scenario.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
