Aging of LAB-based liquid scintillator in stainless steel containers

Types 316 and 304 stainless steel are two candidates for the storage vessels and piping systems of LABbased liquid scintillator（LS） in the JUNO experiment. LS aging experiments are carried out at temperatures of 40 and 25. After 192 days aging at 40, the attenuation length of LS was reduced by 6% in...

Summary:Types 316 and 304 stainless steel are two candidates for the storage vessels and piping systems of LABbased liquid scintillator（LS） in the JUNO experiment. LS aging experiments are carried out at temperatures of 40 and 25. After 192 days aging at 40, the attenuation length of LS was reduced by 6% in a glass container, 12%in a type 304 stainless steel tank, and 10% in a type 316 stainless steel tank. At 25 in 304 and 316 stainless steel tanks, the attenuation length was reduced by 6% after 307 days. The light yield and the absorption spectrum were practically the same as that of the unaged sample. The concentration of element Fe in the LAB-based LS did not show a clear change. Type 316 and 304 stainless steel can be used as vessels and transportation pipeline material for LAB-based LS.
