... The system is based on serial VTT dc SQUID and input l-metal core solenoid transformer. The achieved current resolution is 300 fA/Hz1=2 . Johnson noise of metal resistor and shot noise of tunnel junction were used for current calibration of SQUID read-out. ... An improving of the current sensitivity of the SQUID read-out down to 30 fA/Hz1=2 can be achieved by increasing of the input transformer self-inductance to 600 lH and decreasing of the SQUID flux noise down to 1 lU0 /Hz1=2 . ...
