The runaway electron (RE) plateau can carry up to 80% of the pre-disruption plasma current. The highest runaway currents correspond to the lowest loop voltage, which is contrary to the observations made in most tokamaks. This anomalous behavior is attributed to the acceleration of the pre-existing wave resonant suprathermal electrons by lower hybrid waves during the disruption decay phase. Two distinct types of RE-related relaxation phenomena, distinguished on the basis of the amplitude of the magnetic fluctuations, have been found during the disruptions. Large-amplitude magnetohydrodynamic activity with indications of RE loss is observed during the RE plateau when the edge safety factor decreases to less than 3, and the external kink mode is discussed to resolve this anomaly. Burst-like relaxations with small-amplitude magnetic fluctuations and ∼0.6 kHz frequency are confirmed from the spikes in the hard x-ray array signals under a negative loop voltage. Measurement of the RE energy distribution suggests that the instability is driven by medium-energy REs. 000904079 536__ $$0G:(DE-HGF)POF4-134$$a134 - Plasma-Wand-Wechselwirkung (POF4-134)$$cPOF4-134$$fPOF IV$$x0 000904079 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000904079 7001_ $$0P:(DE-Juel1)145673$$aZeng, L.$$b1 000904079 7001_ $$0P:(DE-Juel1)169330$$aChen, D.$$b2 000904079 7001_ $$0P:(DE-HGF)0$$aSun, Y.$$b3 000904079 7001_ $$0P:(DE-Juel1)176864$$aZhao, H.$$b4$$ufzj 000904079 7001_ $$0P:(DE-HGF)0$$aZhou, T.$$b5 000904079 7001_ $$0P:(DE-HGF)0$$aTi, A.$$b6 000904079 7001_ $$0P:(DE-Juel1)180805$$aLin, S.$$b7 000904079 7001_ $$0P:(DE-Juel1)145882$$aZhou, R.$$b8 000904079 7001_ $$0P:(DE-HGF)0$$aZhu, X.$$b9 000904079 7001_ $$0P:(DE-HGF)0$$aQian, J.$$b10 000904079 7001_ $$aLiu, H.$$b11 000904079 7001_ $$0P:(DE-HGF)0$$aJie, Y.$$b12 000904079 7001_ $$0P:(DE-Juel1)130088$$aLiang, Yunfeng$$b13$$eCorresponding author 000904079 7001_ $$aGao, X.$$b14 000904079 773__ $$0PERI:(DE-600)2037980-8$$a10.1088/1741-4326/abf62f$$gVol. 61, no. 7, p. 076003 -$$n7$$p076003 -$$tNuclear fusion$$v61$$x0029-5515$$y2021 000904079 8564_ $$uhttps://juser.fz-juelich.de/record/904079/files/Tang_2021_Nucl._Fusion_61_076003.pdf$$yRestricted 000904079 909CO $$ooai:juser.fz-juelich.de:904079$$pVDB 000904079 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)187223$$aForschungszentrum Jülich$$b0$$kFZJ 000904079 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)176864$$aForschungszentrum Jülich$$b4$$kFZJ 000904079 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130088$$aForschungszentrum Jülich$$b13$$kFZJ 000904079 9131_ $$0G:(DE-HGF)POF4-134$$1G:(DE-HGF)POF4-130$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Energie$$lFusion$$vPlasma-Wand-Wechselwirkung$$x0 000904079 9141_ $$y2021 000904079 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2021-01-27$$wger 000904079 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium$$d2021-01-27$$wger 000904079 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bNUCL FUSION : 2019$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-01-27 000904079 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2021-01-27 000904079 9201_ $$0I:(DE-Juel1)IEK-4-20101013$$kIEK-4$$lPlasmaphysik$$x0 000904079 980__ $$ajournal 000904079 980__ $$aVDB 000904079 980__ $$aI:(DE-Juel1)IEK-4-20101013 000904079 980__ $$aUNRESTRICTED 000904079 981__ $$aI:(DE-Juel1)IFN-1-20101013
