Title SIMPLE ALUMINUM SEALING AGAINST SUPERFLUID HEIUM
Type Poster cavity design / fabrication / treatment
Abstract Indium sealing is well established for superfluid helium in superconducting application but the sticky material brings an indium contamination during cavity disassembly. DESY has already successfully changed indium to other aluminium alloy material. We are also looking for other simple, cheap and reliable sealing method instead of indium. We are investing fine pure aluminium ring sealing, which is a square cross-section 1mm x 1mm. We tested it for several material combinations between flange and bolt and get good results. In this paper the results will be reported.
