Abstract
The stability and nonuniformity of the helium flow in a continuous-flo w heat vessel have been measured, and their dependence on temperature is interpreted in terms of the heat exchange and hydrodynamics of the helium flow. It is shown that the temperature gradient along the sampl e can be as high as 5-degrees-K/cm over a broad temperature range, and hence the main task of continuous-flow heat-vessel designers is to el iminate the temperature gradient at the sample site.
