| Popis: | It is shown that using the state-of-the-art quantum interferometer (SQUID) with the resolution 10-6 Φ0 Hz-1/2 = 2.07 × 10-21 Wb Hz-1/2, coupled to a magnetostrictor, playing the role of tensomagnetic transducer, it is possible to construct a system for detecting pressure variations with the ultimate sensitivity of 10-13 Pa Hz-1/2 and for measuring specific elongation with the sensitivity of 10-24 Hz-1/2. The analysis of physical grounds of the inverse magnetostriction effect demonstrates concrete ways to essentially higher efficiency of tensomagnetic conversion. The estimates performed demonstrate the possibility of using the SQUID/magnetostrictor system as a detector of gravitational waves. Other possibilities of using this system for solving both fundamental and applied problems are also considered. |
