Using hydrogen, nitrogen and helium as working gas, a gap of 18 µm was measured. With hydrogen, an ON/OFF switching ratio higher than 100 was obtained at 150 K. A sorption pump was integrated to the GGHS and filled with the metal hydride ZrMn2 to overcome the very low adsorption of hydrogen with activated carbon, material frequently used to manage the pressure in the gap. This solution allowed to reach both ON and OFF states by varying its temperature between 150 K and 300 K. The results obtained suggest that the proposed design allows for the development of tunable hydrogen heat switches while keeping the assembly very simple and sturdy.LIBPhys-UNLDF – Departamento de FísicaRUNBarreto, JorgeMartins, DanielBranco, Moritz CasteloBranco, JoaquimGonçalves, António PereiraTirolien, ThierryBonfait, Grégoire2023-09-21T00:32:17Z2021-102021-10-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10362/141058eng0011-2275PURE: 42000588https://doi.org/10.1016/j.cryogenics.2021.103365info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T05:18:20Zoai:run.unl.pt:10362/141058Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:49:53.959792Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
