FERMILAB-POSTER-21-098-STUDENT Fermilab currently designing a High Field Cable Test Facility. Its purpose is to test superconducting cables and magnets. The goal of this project was to analyze the thermal performance of three different seal designs and provide recommendations for the HFVMTF. The seals being tested were a PTFE Plug, an Energized Spring Seal and a CF Flange Seal. Primary analysis provided us with a baseline for the heat flow rate. Modifications were made to the CF Flange Seal due

... to poor performance. The seals were then modeled in more detail and FEA was run to get a more specific grasp of the heat flow rate. Structural analysis was done on the CF Flange Seal due to a possibility of over constraining. The results of the project found that the PTFE Plug would be the most advantageous seal to use in the HFVMTF.
