摘要：
For investigating vortex formation in rotating superfluid He-3-B at high velocities of vortex-free superflow, the usual geometry is a cylindrical sample, which is connected via an orifice and a liquid He-3 column to the heat exchanger on the refrigerator. The orifice prevents vortices, created in the heat exchanger, from flowing into the sample until the rotation velocity reaches a critical value Q,. We describe NMR measurements of Omega(c) as a function of temperature and discuss the results in terms of vortex-line pinning at the rim of the orifice. (C) 2003 Elsevier Science B.V.
