With a 30 cubic meter volume, a superconducting coil system operating at 2.5 T, and steady-state heating capability of eventually up to 10 MW, it was built to demonstrate the benefits of optimized stellarators at parameters approaching those of a fusion power plant. We report here on the first results with the test divertor installed, during the second operation phase, which was performed in the second half of 2017. Operation with a divertor, and the addition of several new fueling systems, allowed higher density operation in hydrogen as well as helium. The effects that higher density operation had on both divertor operation and global confinement will be described. In particular, at high densities detachment was observed, and the highest fusion triple product for a stellarator was achieved. 000858313 536__ $$0G:(DE-HGF)POF3-174$$a174 - Plasma-Wall-Interaction (POF3-174)$$cPOF3-174$$fPOF III$$x0 000858313 588__ $$aDataset connected to CrossRef 000858313 7001_ $$0P:(DE-Juel1)130373$$aKönig, Ralf$$b1 000858313 7001_ $$0P:(DE-HGF)0$$aKrychowiak, Maciej$$b2 000858313 7001_ $$00000-0002-6557-3497$$aJakubowski, Marcin$$b3 000858313 7001_ $$0P:(DE-HGF)0$$aBaldzuhn, Jürgen$$b4 000858313 7001_ $$00000-0003-4289-3532$$aBozhenkov, Sergey$$b5 000858313 7001_ $$0P:(DE-HGF)0$$aFuchert, Golo$$b6 000858313 7001_ $$00000-0002-2107-5488$$aLangenberg, Andreas$$b7 000858313 7001_ $$0P:(DE-HGF)0$$aNiemann, Holger$$b8 000858313 7001_ $$0P:(DE-HGF)0$$aZhang, Daihong$$b9 000858313 7001_ $$0P:(DE-HGF)0$$aRahbarnia, Kian$$b10 000858313 7001_ $$00000-0003-0621-6913$$aBosch, Hans-Stephan$$b11 000858313 7001_ $$00000-0001-6316-5441$$aKazakov, Yevgen$$b12 000858313 7001_ $$0P:(DE-Juel1)129976$$aBrezinsek, Sebastijan$$b13 000858313 7001_ $$0P:(DE-Juel1)161317$$aGao, Yu$$b14 000858313 7001_ $$0P:(DE-HGF)0$$aPablant, Novimir$$b15 000858313 773__ $$0PERI:(DE-600)1473144-7$$a10.1088/1361-6587/aaec25$$gVol. 61, no. 1, p. 014035 -$$n1$$p014035 -$$tPlasma physics and controlled fusion$$v61$$x1361-6587$$y2019 000858313 8564_ $$uhttps://juser.fz-juelich.de/record/858313/files/Pedersen_2019_Plasma_Phys._Control._Fusion_61_014035.pdf$$yOpenAccess 000858313 8564_ $$uhttps://juser.fz-juelich.de/record/858313/files/Pedersen_2019_Plasma_Phys._Control._Fusion_61_014035.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000858313 909CO $$ooai:juser.fz-juelich.de:858313$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000858313 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130373$$aForschungszentrum Jülich$$b1$$kFZJ 000858313 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129976$$aForschungszentrum Jülich$$b13$$kFZJ 000858313 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)161317$$aForschungszentrum Jülich$$b14$$kFZJ 000858313 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 000858313 9141_ $$y2019 000858313 915__ $$0LIC:(DE-HGF)CCBY3$$2HGFVOC$$aCreative Commons Attribution CC BY 3.0 000858313 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000858313 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000858313 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bPLASMA PHYS CONTR F : 2017 000858313 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000858313 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000858313 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000858313 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000858313 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000858313 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000858313 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000858313 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium 000858313 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000858313 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000858313 9201_ $$0I:(DE-Juel1)IEK-4-20101013$$kIEK-4$$lPlasmaphysik$$x0 000858313 9201_ $$0I:(DE-Juel1)IEK-6-20101013$$kIEK-6$$lNukleare Entsorgung und Reaktorsicherheit$$x1 000858313 9801_ $$aFullTexts 000858313 980__ $$ajournal 000858313 980__ $$aVDB 000858313 980__ $$aUNRESTRICTED 000858313 980__ $$aI:(DE-Juel1)IEK-4-20101013 000858313 980__ $$aI:(DE-Juel1)IEK-6-20101013 000858313 981__ $$aI:(DE-Juel1)IFN-1-20101013 000858313 981__ $$aI:(DE-Juel1)IFN-2-20101013 000858313 981__ $$aI:(DE-Juel1)IFN-2-20101013
