Upstream and downstream concentrations of ³ $He$ He as a function of the filtration time. (a) upstream concentration for YBCO-123 as compared to MWCNTs at 55 mW heater power. (b) upstream and downstream ³ $He$ He concentrations measured simultaneously, black arrows mark the appearance of the lambda transition and switching on the heater to drive the fountain effect. Insert shows the mass spectrum with additional arrows indicating the ³ $He$ He and ⁴He $^{4} He$ concentrations.
