| Popis: |
A low-volume high-performance directly coupled electronics for the high-T/sub c/ DC SQUID magnetometers has been developed and tested. This electronics is based on a liquid nitrogen cooled preamplifier with the white noise level close to 0.25 nV/Hz/sup 1/2/, packed in the volume less than 3 cm/sup 3/ and results in a typical 3 dB bandwidth of about 1 MHz, maximum dynamic range 140 dB for frequencies up to 1 kHz and the maximum slew rate more than 10/sup 6/ flux quanta in second with a middle-quality DC SQUID sensor. |
