The approach presented suggests how to use ITER such that DEMO can be extrapolated with maximum confidence and a development path for plasma scenarios in ITER follows from our approach, moving from low β N and q typical for the present Q = 10 scenario to higher values needed for steady state. A numerical example is given, indicative of the feasibility of the approach, and it is backed up by more detailed 1.5-D calculation using the ASTRA code. We note that ideal MHD stability analysis of the DEMO operating point indicates that it is located between the no-wall and the ideal wall β-limit, which may require active stabilization. The DEMO design could also be a pulsed fallback solution should a stationary operation turn out to be impossible. 000860633 536__ $$0G:(DE-HGF)POF3-174$$a174 - Plasma-Wall-Interaction (POF3-174)$$cPOF3-174$$fPOF III$$x0 000860633 588__ $$aDataset connected to CrossRef 000860633 7001_ $$0P:(DE-HGF)0$$aTräuble, F.$$b1 000860633 7001_ $$0P:(DE-Juel1)129967$$aBiel, W.$$b2$$eCorresponding author$$ufzj 000860633 7001_ $$0P:(DE-HGF)0$$aFable, E.$$b3 000860633 7001_ $$0P:(DE-HGF)0$$aKemp, R.$$b4 000860633 7001_ $$0P:(DE-HGF)0$$aLux, H.$$b5 000860633 7001_ $$0P:(DE-HGF)0$$aSiccinio, M.$$b6 000860633 7001_ $$0P:(DE-HGF)0$$aWenninger, R.$$b7 000860633 773__ $$0PERI:(DE-600)2037980-8$$a10.1088/1741-4326/aa739e$$gVol. 57, no. 8, p. 086002 -$$n8$$p086002 -$$tNuclear fusion$$v57$$x1741-4326$$y2017 000860633 8564_ $$uhttps://juser.fz-juelich.de/record/860633/files/Zohm_2017_Nucl._Fusion_57_086002.pdf$$yRestricted 000860633 8564_ $$uhttps://juser.fz-juelich.de/record/860633/files/Zohm_Stepladder.pdf$$yOpenAccess 000860633 8564_ $$uhttps://juser.fz-juelich.de/record/860633/files/Zohm_2017_Nucl._Fusion_57_086002.pdf?subformat=pdfa$$xpdfa$$yRestricted 000860633 8564_ $$uhttps://juser.fz-juelich.de/record/860633/files/Zohm_Stepladder.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000860633 909CO $$ooai:juser.fz-juelich.de:860633$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000860633 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129967$$aForschungszentrum Jülich$$b2$$kFZJ 000860633 9131_ $$0G:(DE-HGF)POF3-174$$1G:(DE-HGF)POF3-170$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lKernfusion$$vPlasma-Wall-Interaction$$x0 000860633 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000860633 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000860633 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bNUCL FUSION : 2017 000860633 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000860633 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000860633 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000860633 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000860633 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000860633 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000860633 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000860633 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium 000860633 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000860633 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000860633 9201_ $$0I:(DE-Juel1)IEK-4-20101013$$kIEK-4$$lPlasmaphysik$$x0 000860633 9801_ $$aFullTexts 000860633 980__ $$ajournal 000860633 980__ $$aVDB 000860633 980__ $$aUNRESTRICTED 000860633 980__ $$aI:(DE-Juel1)IEK-4-20101013 000860633 981__ $$aI:(DE-Juel1)IFN-1-20101013
