Seit Jahrzehnten werden hauptsächlich die Blaubadmethode und das Verfahren des mikrobiellen Eindringens eingesetzt. In jüngster Zeit drängen offizielle Richtlinien wie die USP <1207> auf den Einsatz deterministischer und zerstörungsfreier Methoden. In einer Vergleichsstudie sind die bekannten Studien von Kirsch und Burrel zusammengebracht worden. Mehr als 500 Glasfläschchen wurden mit Defekten (Mikroröhrchen und Glasmikropipetten) präpariert. Die Proben sind neben dem Blaubadtest mit drei vakuumbasierten Dichtheitsprüfmethoden geprüft worden: HeliumLecktest, optische Emissionsspektroskopie und Mass Extraction. Die Studienergebnisse vergleichen die vakuumbasierten Methoden mit dem Blaubadtest und bilden eine Entscheidungshilfe, die Methode zu wechseln und den neuen Richtlinien zu entsprechen.","PeriodicalId":42842,"journal":{"name":"Vakuum in Forschung und Praxis","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41693893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The currently proposed plasma operation plan for the six torus cryopumps is staggered for all fueling rate and plasma durations and therefore variable tritium inventories need to be handled. The ITER cryopumps and the backing vacuum pumping system are custom made tritium compatible pumping trains. Their compliant matrix not only asks for pumping efficiencies and hydrogen confinement but also respecting the specific tritium and deuterium (DT) inventories for measures on radiation protection and fire safety. In this article, we present a possible operation plan for torus vacuum pumping system in combinations with roughing pump trains for the ITER baseline plasma scenario. The operation of the vacuum system is driven by DT inventories in the different pumps and building sectors.","PeriodicalId":42842,"journal":{"name":"Vakuum in Forschung und Praxis","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47190862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
