Abstract
Systems, methods, and devices of the various embodiments may provide a high-thermal-stability cryogenic-kinematic-mount with passive magnetic vibration damping. In various embodiments, the cryogenic-kinematic-mount may be configured for use in sub-Kelvin environments. Various embodiment cryogenic-kinematic-mounts may provide dampening and thermal isolation without a need for electronics or software feedback-based controls for the mounts. Various embodiments cryogenic-kinematic-mounts may be passive mounts configured to not require dampening controls.
Claims19
A cryogenic-kinematic-mount, the cryogenic-kinematic-mount comprising:
- a cold side stage;
- a warmer side stage opposite the cold side stage;
- and
- a dampening and tensioning system between the cold side stage and warmer side stage,
- wherein the dampening and tensioning system includes at least one magnetic array, wherein the dampening and tensioning system provides dampening and thermal isolation between the cold side stage and the warmer side stage, and wherein the dampening and tensioning system further includes at least one high electrical conductivity metal plate separated from the at least one magnetic array by a gap therebetween, wherein the at least one high electrical conductivity metal plate comprises copper.
A cryogenic-kinematic-mount, comprising:
- a cold side stage;
- a warmer side stage opposite the cold side stage;
- and
- a dampening and tensioning system between the cold side stage and warmer side stage,
- wherein the dampening and tensioning system includes two magnetic arrays opposite two metal plates, wherein the dampening and tensioning system provides dampening and thermal isolation between the cold side stage and the warmer side stage, and wherein the dampening and tensioning system includes a plurality of synthetic fiber strands coupled to the cold side stage and warmer side stage.
