| Research Abstract |
We have developed an active magnetic shield using a pair of magnetic shells of half cylindrical structure made of amorphous tapes and FRP composite. Active compensation technique to expel magnetic noises coming from outside has beendeveloped. We have also developed a wide-band, high resolution magnetic sensor andlow-noise power amplifiers for the compensation system. We applied the said shield for the MCG measurement by a SQUID system and, for the first time, by a fluxgate sensor array of 6 channels. A method has been developed by which accumulated location of magnetic markers in a phantom can be identified by mapping magnetic fields in the developed magnetic shield.
