Abstract

An experiment to investigate the free decay of quantized turbulence in isotopically pure superfluid He-4 at millikelvin temperatures is discussed. The vortices are created by a vibrating grid, and detected by their trapping of negative ions. Preliminary results suggest the existence of a temperature-independent vortex decay mechanism below T » 70 mK.
