射频超导量子干涉器,简称RFSQVID,它是由一个约瑟夫逊结和一个超导环连接而组成。RFSQVID的磁灵敏度可达到1×10~(-19)Wb或更高。可以用来测量各种生物磁场,如人的脑磁、心磁;研究古地磁,寻找矿物,如落底石油;以及测量引力波和磁单极子等;在计量方面,用它可以做成灵敏度高达10~(-12)A及10~(-15)V的检流计。用SQVID制成的超导电流比较仪,精度可达10~(-11)。此外,在测量小电压,小电流,小电阻等方面灵敏度都比常规仪
RF Superconducting Quantum Interferometer, referred to as RFSQVID, is composed of a Josephson junction and a superconducting ring connected. RFSQVID magnetic sensitivity can reach 1 × 10 ~ (-19) Wb or higher. Can be used to measure a variety of biological magnetic field, such as human brain magnetic, magnetic; study of paleomagnetic, looking for minerals, such as the bottom of the oil; and the measurement of gravitational waves and magnetic monopoles, etc .; in terms of measurement, Sensitivity up to 10 ~ (-12) A and 10 ~ (-15) V galvanometer. Using SQVID superconducting current comparator, the accuracy of up to 10 ~ (-11). In addition, in the measurement of small voltage, small current, small resistance sensitivity than conventional instrument
