摘要：
A highly sensitive galvanometer operating at liquid-nitrogen temperature for direct and low-frequency current measurements was developed on the basis of a HTSC SQUID. The direct-current sensitivity of the galvanometer is approximately 0.5 nA at an internal resistance of about 20 OMEGA. Its energy resolution in the white noise region is 2 x 10(-21) J/Hz.
