The conceptual study of a suite of DEMO diagnostics is on-going. Among these, a Gamma-Ray Spectrometric Instrument (GRSI) is being investigated to assess its performance and information quality in view of DEMO control. The GRSI foresees radial-orthogonal multi-line of sight viewing DEMO plasma across its poloidal section as a further development of the Gamma-Ray Camera of JET and of the Radial Gamma-Ray Spectrometers proposed for ITER but with stricter technological constraints. These include surface availability in the Tritium Breeding Blankets of DEMO vessel inner wall for diagnostics collimators openings, diagnostics distance from the plasma, neutron irradiation and activation of the reactor structures. On DEMO the gamma-ray (γ) emission from DT plasmas consists of T(d,γ)5He (Eγ = 16.63 MeV) and T(p,γ)4He (Eγ = 19.81 MeV) reactions which for their high Eγ would allow in principle for background-free measurements. This work reports the assessment on the GRSI diagnostic capability. Reactions cross sections are assessed and used for the calculations of the reactions γ emission energy spectrum under DEMO DT plasma conditions and compared with 14 MeV neutron emissions before and after the GRSI collimator. Investigation of the GRSI γ spectrometers performance is also presented. Measurement of the γ emission intensity of T(d,γ)5He can be in principle used as an independent assessment of DEMO DT plasmas fusion power. 000859893 536__ $$0G:(DE-HGF)POF3-174$$a174 - Plasma-Wall-Interaction (POF3-174)$$cPOF3-174$$fPOF III$$x0 000859893 588__ $$aDataset connected to CrossRef 000859893 7001_ $$0P:(DE-HGF)0$$aRigamonti, D.$$b1 000859893 7001_ $$0P:(DE-HGF)0$$aNocente, M.$$b2 000859893 7001_ $$0P:(DE-HGF)0$$aRebai, M.$$b3 000859893 7001_ $$0P:(DE-HGF)0$$aTardocchi, M.$$b4 000859893 7001_ $$0P:(DE-HGF)0$$aCecconello, M.$$b5 000859893 7001_ $$0P:(DE-HGF)0$$aConroy, S.$$b6 000859893 7001_ $$0P:(DE-HGF)0$$aHjalmarsson, A.$$b7 000859893 7001_ $$0P:(DE-HGF)0$$aFranke, T.$$b8 000859893 7001_ $$0P:(DE-Juel1)129967$$aBiel, W.$$b9 000859893 773__ $$0PERI:(DE-600)1492280-0$$a10.1016/j.fusengdes.2018.05.041$$gVol. 136, p. 1494 - 1498$$nPart B$$p1494 - 1498$$tFusion engineering and design$$v136$$x0920-3796$$y2018 000859893 8564_ $$uhttps://juser.fz-juelich.de/record/859893/files/1-s2.0-S0920379618304757-main.pdf$$yRestricted 000859893 8564_ $$uhttps://juser.fz-juelich.de/record/859893/files/1-s2.0-S0920379618304757-main.pdf?subformat=pdfa$$xpdfa$$yRestricted 000859893 909CO $$ooai:juser.fz-juelich.de:859893$$pVDB 000859893 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129967$$aForschungszentrum Jülich$$b9$$kFZJ 000859893 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 000859893 9141_ $$y2018 000859893 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000859893 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bFUSION ENG DES : 2017 000859893 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000859893 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000859893 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000859893 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000859893 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000859893 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000859893 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000859893 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology 000859893 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000859893 9201_ $$0I:(DE-Juel1)IEK-4-20101013$$kIEK-4$$lPlasmaphysik$$x0 000859893 980__ $$ajournal 000859893 980__ $$aVDB 000859893 980__ $$aI:(DE-Juel1)IEK-4-20101013 000859893 980__ $$aUNRESTRICTED 000859893 981__ $$aI:(DE-Juel1)IFN-1-20101013
