内容記述タイプ Abstract
内容記述 The circuit parameters of a dc SQUID magnetometer have been optimized by computer simulations. Our principle of optimization is to minimize the field resolution. We have optimized the circuit parameters of a dc SQUID magnetometer, such as a .Ketchen type, Drung type, directly-coupled type, etc. The only noise source was assumed to be thermal noise from the shunt resistors. For a Ketchen type SQUID, our results show that the inductance of the input coil and the washer coil should be larger than that reported previously. It is also the case for a Drung type SQUID that the inducatance of the SQUID washer coil should be slightly increased. By this design method, the optimum field resolution of a Ketchen type SQUID magnetometer is improved by a factor of 2/3. Furthermore, we compared the resolution of 3 types of dc SQUIDs and concluded that the optimum type of SQUID depends on the value of the critical current and the radius of the pick-up coil. Finally, we have proposed a new design method that can optimize the field resolution of dc SQUIDs under constraints on the critical current and the spatial resolution.
