This study explores the viability of PEEK as a vacuum window material in high-power radio frequency (RF) couplers. Traditionally, materials such as ceramics are employed for this purpose; however, they are costly to manufacture and impose limitations during the design process. PEEK offers additional advantages, including the possibility of additive manufacturing, which enables the integration of cooling channels for efficient thermal management. The research evaluates PEEK's electrical, thermal, and mechanical properties under conditions typical of high-power RF couplers, such as vacuum stability, RF-induced heating, and electromagnetic transparency. At the Institute for Applied Physics (IAP), PEEK is tested as a vacuum window material in high-power experiments up to 35 kW. Following these tests, the material is analyzed to assess its performance and suitability for RF applications. 621 - Accelerator Research and Development (POF4-621) G:(DE-HGF)POF4-621 POF4-621 POF IV 0 Accelerator physics (HFHF project) (I:(DE-Ds200)HFHF-ACC) I:(DE-Ds200)HFHF-ACC I:(DE-Ds200)HFHF-ACC 1 Dataset connected to DataCite Accelerator Physics Other mc4-hadron-accelerators - MC4: Hadron Accelerators Other MC4.A08 - MC4.A08 Linear Accelerators Other theory no experiment theory work (theory) EXP:(DE-Ds200)theory-20200803 EXP:(DE-Ds200)no_experiment-20200803 EXP:(DE-Ds200)no_experiment-20200803 0 Podlech, Holger P:(DE-HGF)0 1 Storch, Julius 2 Kümpel, Klaus 3 10.18429/JACOW-IPAC2025-TUPS041 OpenAccess http://repository.gsi.de/record/364081/files/TUPS041.pdf OpenAccess pdfa http://repository.gsi.de/record/364081/files/TUPS041.pdf?subformat=pdfa oai:repository.gsi.de:364081 openaire open_access VDB driver dnbdelivery GSI Helmholtzzentrum für Schwerionenforschung GmbH I:(DE-Ds200)20121206GSI GSI 1 P:(DE-HGF)0 DE-HGF Forschungsbereich Materie Materie und Technologie G:(DE-HGF)POF4-620 G:(DE-HGF)POF4-621 G:(DE-HGF)POF4 G:(DE-HGF)POF4-600 G:(DE-HGF)POF Accelerator Research and Development 0 2025 OpenAccess StatID:(DE-HGF)0510 StatID Creative Commons Attribution CC BY 4.0 LIC:(DE-HGF)CCBY4 HGFVOC I:(DE-Ds200)FHF-20200605OR451 FHF Helmholtz ForschAkad Hess. f.
