摘要：

We have measured the noise performance of a composite niobium/YBCO point contact 2-hole SQUID, at 4.2K in both rf and dc bias modes. The noise was measured by a technique which allowed the component which was flux noise to be measured. The flux noise was found to be the same in both bias modes. A direct measurement of the noise in a single hole in the same sample was made as a function of temperature and was found to display two peaks. Possible causes are discussed.
