Abstract

A 19-channel SQUID system for biomagnetic measurements has been developed. This system differs from standard instruments in its modular approach. Various gradiometers can be coupled to the SQUIDs, the cryogenic system allows the exchange of single channels and the electronics is based on a cassette system. Problems with thermal insulation, vibrations of the gradiometers and tilted gradiometer geometries are discussed and solutions are presented.

摘要

已开发出一种用于生物磁测量的19通道超导量子干涉装置（SQUID）系统。该系统在模块化方法上与标准仪器不同。各种梯度仪可与SQUID耦合，低温系统允许单通道更换，并且电子设备基于盒式系统。文中讨论了热绝缘、梯度仪振动和梯度仪几何形状倾斜等问题并给出了解决方案。
