Abstract: An inventive magnetic filling material for bridging interspaces in magnetic shields for shielding static or low-frequency magnetic fields. The magnetic filling material comprises at least one matrix material and at least one magnetic component embedded into the matrix material. The magnetic component has magnetically shielding properties.

Abstract: An inventive cryostat for use in a biomagnetic measurement system. The cryostat comprises at least one inner vessel and at least one outer vessel, and at least one cavity arranged between the inner vessel and the outer vessel, wherein negative pressure can be applied to the cavity. At least one radiation shield for shielding the cryostat from electromagnetic radiation is housed in the cavity. The cryostat furthermore comprises at least one ground lead for connecting the radiation shield to an electrical ground or earth. The ground lead is connected to the radiation shield in the cavity. The cryostat has at least one electrical feed-through, by means of which the ground lead can be contacted electrically from an outer side of the cryostat through the outer vessel.

Abstract: A cryostat (110) for use in a biomagnetic measurement system is proposed. The cryostat (110) comprises at least one inner vessel (112) and at least one outer vessel (114), and at least one cavity (126) arranged between the inner vessel (112) and the outer vessel (114), in which negative pressure can be applied to the cavity (126). The inner vessel (112) has a base part (136) and a sidewall (134) connected to the base part (136) in a circumferential connection region (140). The inner vessel (112) has a circumferential strengthening element (142) in the connection region (140), with the strengthening element (142) having a first fiber composite material with a first fibrous material (158) with an anisotropic orientation and with a local preferred orientation, the local preferred orientation being oriented substantially in the circumferential direction of the cryostat (110).

The cryostat (110) comprises at least one inner vessel (112) and at least one outer vessel (114), and at least one cavity (126) arranged between the inner vessel (112) and the outer vessel (114). Negative pressure can be applied to the cavity (126). The outer vessel (114) has a base part (130). The base part (130) has a region of varying thickness (166) with a concentrically varying base thickness, with the base thickness assuming a smaller value toward the center of the base part (130) than in an outer region.
