Abstract

We have constructed an experiment designed to study Josephson phenomena in ⁴He. Motivated by reports and our ideas for novel silicon nanofabrication techniques, we designed the experiment to study the possibility of a transition from stochastic to coherent phase slippage. Here we briefly describe the nanofabrication of sub-15 nm aperture arrays and show preliminary data. For temperatures below 2 K, these data show temperature dependence of the superfluid critical velocity through the weak link which is characteristic of phase-slip limited flow.
