Squid-magnetometer with a shielding envelope against electromagnetic interference fields

摘要

Screening envelope (19) for SQUID magnetometers against electromagnetic interference fields from electrically conductive screening material for adequate radio-frequency screening with low noise contribution, which completely encloses an intrinsically non-screening cryostat (10) and exhibits a predetermined surface resistance and is constructed of at least one layer of the screening material in order not to increase the total magnetometer noise if possible.
