One of the most important challenges in recent years was the development of the hybrid scenario for D-T, based on reference deuterium and tritium plasmas. This kind of scenario, one of the foreseen for ITER, is characterized by a low current plasma and a high normalized beta \u03b2N factor compared to the parallel optimized baseline scenario [Hobirk et al., Plasma Phys. Controlled Fusion 54, 095001 (2012)]. As the experiments have shown, controlling the plasma edge in the different phases of the hybrid scenario becomes more difficult with higher isotope mass, and therefore, are also in risk of impurity accumulation [Hobirk et al., Nucl. Fusion 63, 112001 (2023)]. For this reason, investigation of the impurity behavior, as well as their control, constituted the crucial issue. The present contribution aims to compare mid-Z and high-Z impurities behavior within H-mode hybrid discharges in D and T plasmas, as well as D and DT plasmas. Detailed analysis shows that in the H-mode regime in the hybrid scenario, higher impurity radiation is observed for DT in comparison to D plasmas, as well as for T compared to D plasmas. Additionally, it was noticed that the most significant contribution to the plasma radiated power comes from W and to a lesser extent from Ni (\u223c10%). Moreover, it was found that an earlier transition from small edge localized modes (ELMs) to ELM-free phase can result in the earlier increase in impurities.<\/jats:p>","DOI":"10.1063\/5.0207200","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T13:29:50Z","timestamp":1715693390000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Study of impurity behavior in JET-ILW hybrid scenario with deuterium, tritium, and deuterium\u2013tritium plasmas"],"prefix":"10.1063","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9765-6027","authenticated-orcid":false,"given":"N.","family":"Wendler","sequence":"first","affiliation":[{"name":"Institute of Plasma Physics and Laser Microfusion 1 , Warsaw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4931-728X","authenticated-orcid":false,"given":"A.","family":"Chomiczewska","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics and Laser Microfusion 1 , Warsaw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2683-8453","authenticated-orcid":false,"given":"W.","family":"Gromelski","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics and Laser Microfusion 1 , Warsaw, Poland"}]},{"given":"E.","family":"Kowalska-Strz\u0119ciwilk","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics and Laser Microfusion 1 , Warsaw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2766-8612","authenticated-orcid":false,"given":"I.","family":"Ivanova-Stanik","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics and Laser Microfusion 1 , Warsaw, Poland"}]},{"given":"C.
