This approach has been confirmed by numerical simulations with the help of ANSYS software. For experimental tests, two 10 × 10 mm2 samples of micro-structured tungsten were manufactured. These consisted of 2000 and 5000 vertically packed tungsten fibres with dimensions of Ø240 µm × 2.4 mm and Ø150 µm × 2.4 mm, respectively. The 1.2 mm bottom parts of the fibres are embedded in a copper matrix. The top parts of the fibres have gaps about of 10 µm so they are not touching each others. The top of all tungsten fibres was electro-polished. A Nd:YAG laser with a pulse duration 1 ms and a pulse repetition frequency of 25 Hz was used to simulate up to 105 ELM-like heat pulses. No damage on either of the micro-structured tungsten samples were observed. Neon plasma erosion rate and fuel retention of the micro-structured tungsten samples were almost identical to bulk tungsten samples. 000865898 536__ $$0G:(DE-HGF)POF3-174$$a174 - Plasma-Wall-Interaction (POF3-174)$$cPOF3-174$$fPOF III$$x0 000865898 588__ $$aDataset connected to CrossRef 000865898 7001_ $$0P:(DE-Juel1)130158$$aSergienko, G.$$b1 000865898 7001_ $$0P:(DE-Juel1)5089$$aTokar, M.$$b2 000865898 7001_ $$0P:(DE-Juel1)7884$$aBorodin, D.$$b3 000865898 7001_ $$0P:(DE-Juel1)158050$$aDittmar, T.$$b4 000865898 7001_ $$0P:(DE-Juel1)130070$$aKreter, A.$$b5 000865898 7001_ $$0P:(DE-Juel1)167463$$aMartynova, Y.$$b6 000865898 7001_ $$0P:(DE-Juel1)139534$$aMöller, S.$$b7 000865898 7001_ $$0P:(DE-Juel1)162160$$aRasiński, M.$$b8 000865898 7001_ $$0P:(DE-Juel1)129811$$aWirtz, M.$$b9 000865898 7001_ $$0P:(DE-Juel1)129751$$aLoewenhoff, Th.$$b10 000865898 7001_ $$0P:(DE-Juel1)171293$$aDorow-Gerspach, D.$$b11 000865898 7001_ $$0P:(DE-Juel1)166383$$aYuan, Y.$$b12 000865898 7001_ $$0P:(DE-Juel1)129976$$aBrezinsek, S.$$b13 000865898 7001_ $$0P:(DE-Juel1)6784$$aUnterberg, B.$$b14 000865898 7001_ $$0P:(DE-Juel1)157640$$aLinsmeier, Ch.$$b15 000865898 773__ $$0PERI:(DE-600)2808888-8$$a10.1016/j.nme.2019.02.007$$gVol. 19, p. 7 - 12$$p7 - 12$$tNuclear materials and energy$$v19$$x2352-1791$$y2019 000865898 8564_ $$uhttps://juser.fz-juelich.de/record/865898/files/1-s2.0-S2352179118301765-main.pdf$$yOpenAccess 000865898 8564_ $$uhttps://juser.fz-juelich.de/record/865898/files/1-s2.0-S2352179118301765-main.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000865898 909CO $$ooai:juser.fz-juelich.de:865898$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130166$$aForschungszentrum Jülich$$b0$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130158$$aForschungszentrum Jülich$$b1$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)5089$$aForschungszentrum Jülich$$b2$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)7884$$aForschungszentrum Jülich$$b3$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)158050$$aForschungszentrum Jülich$$b4$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130070$$aForschungszentrum Jülich$$b5$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)167463$$aForschungszentrum Jülich$$b6$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)139534$$aForschungszentrum Jülich$$b7$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)162160$$aForschungszentrum Jülich$$b8$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129811$$aForschungszentrum Jülich$$b9$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129751$$aForschungszentrum Jülich$$b10$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171293$$aForschungszentrum Jülich$$b11$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129976$$aForschungszentrum Jülich$$b13$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)6784$$aForschungszentrum Jülich$$b14$$kFZJ 000865898 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)157640$$aForschungszentrum Jülich$$b15$$kFZJ 000865898 9131_ $$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$$x0 000865898 9141_ $$y2019 000865898 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000865898 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000865898 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000865898 915__ $$0StatID:(DE-HGF)0112$$2StatID$$aWoS$$bEmerging Sources Citation Index 000865898 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000865898 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000865898 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000865898 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Peer review 000865898 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000865898 9201_ $$0I:(DE-Juel1)IEK-2-20101013$$kIEK-2$$lWerkstoffstruktur und -eigenschaften$$x0 000865898 9201_ $$0I:(DE-Juel1)IEK-4-20101013$$kIEK-4$$lPlasmaphysik$$x1 000865898 9201_ $$0I:(DE-Juel1)IEK-1-20101013$$kIEK-1$$lWerkstoffsynthese und Herstellungsverfahren$$x2 000865898 9801_ $$aFullTexts 000865898 980__ $$ajournal 000865898 980__ $$aVDB 000865898 980__ $$aI:(DE-Juel1)IEK-2-20101013 000865898 980__ $$aI:(DE-Juel1)IEK-4-20101013 000865898 980__ $$aI:(DE-Juel1)IEK-1-20101013 000865898 980__ $$aUNRESTRICTED 000865898 981__ $$aI:(DE-Juel1)IMD-1-20101013 000865898 981__ $$aI:(DE-Juel1)IFN-1-20101013 000865898 981__ $$aI:(DE-Juel1)IMD-2-20101013
