Abstract

A prototype of SQUID read-out for current measurements at the output of a normal metal hot-electron microbolometer has been developed and tested. The system is based on serial VTT dc SQUID and input μ-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. The current noise spectra of 35 k SIN tunnel junction measured at different bias voltages are presented.
