Patent ID: 11953570
Assignee: BRUKER SWITZERLAND AG
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 0:
1. Nuclear magnetic resonance (NMR) measuring arrangement, comprising
a cryostat having an evacuated vacuum container, wherein the cryostat forms a bore having a bore wall that delimits the vacuum container,
a superconducting magnet coil system having a magnet bore, wherein the magnet coil system is arranged directly inside or indirectly inside the vacuum container, wherein the cryostat, for thermally insulating the magnet coil system, forms one or more evacuated gaps between the superconducting magnetic coil system and the vacuum container in a sequence from the inside out, and wherein the bore extends through the magnet bore, and
an NMR probe having a radio frequency (RF) coil system, wherein the NMR probe is arranged outside the vacuum container, and wherein the NMR probe is arranged at least partially in the bore,
wherein the cryostat forms only one evacuated gap in a space extending between the magnet coil system and the bore wall,
wherein at least a length of a segment of the bore wall is thermally coupled to a heat sink of the cryostat, and
wherein the bore wall also delimits a hermetically sealed space outside the vacuum container,
wherein the sealed space extends in the bore in a longitudinal direction of the cryostat at least over the length of the segment.
