우리는 두 가지 유형의 고급 제품을 제작하고 특성화했습니다.Tc 픽업 루프의 선폭이 다른 평면 SQUID 경도계. 이 장치는 차폐 없이 실험실 환경에서도 FLL(자속 고정 루프) 작동으로 작동했습니다. 차폐실에서 병렬형 소자의 자기장 구배 분해능은 약 0.5pT/cmHz였다.1/2 1kHz 및 2pT/cmHz에서1/2 1Hz에서. 이 장치는 차폐실에서 심전도를 기록하는 것이 가능했습니다. 약 10 pT의 QRS-복합 피크 PP/4mm가 선명하게 관찰됩니다. 메쉬형 장치의 경우 개방형 실험실 환경에서 저주파 소음의 증가가 병렬형 장치의 경우보다 적었습니다.

Abstract: We have fabricated and characterized two types of high-Tc planar SQUID gradiometers having different line width of pickup loops. The device worked in flux-locked loop (FLL) operation even in laboratory environment without any shielding. A magnetic field gradient resolution of a parallel-type device in a lightly shielded room was about 0.5 pT/cmHz1/2 at 1 kHz and 2 pT/cmHz1/2 at 1 Hz. The device was possible to record magnetocardiograms in a shielded room. QRS-complex peaks of about 10 pT PP/4mm are clearly observed. For a mesh-type device, the increase of low frequency noise in the open laboratory environment was less than that for a parallel-type.
