Abstract
The present disclosure includes dipole line trap system, a method for tuning a natural frequency of a dipole line trap system, and seismometer. One embodiment of the dipole line trap system may comprise a first axis unit. The first axis unit may comprise a first group of at least three cylindrical diametric magnets mounted in parallel around a first open region, and a first diamagnetic object in the first open region. In some embodiments, the first axis unit may comprise four cylindrical diametric magnets mounted in parallel around the first open region. In some embodiments, the first axis unit may have a natural frequency of less than 1 Hz.
Claims17
A dipole line trap system comprising:
- a first axis unit, comprising:
- a first group of at least three cylindrical diametric magnets mounted in parallel around a first open region, wherein the first group of at least three cylindrical diametric magnets further define a vertical gap and a horizontal gap therebetween, and wherein a length of the horizontal gap is different than a length of the vertical gap;
- and
- a first diamagnetic object in the first open region.
A seismometer comprising:
- at least two cylindrical diametric magnets each comprising a circular end and length, wherein each of the respective lengths of the at least two cylindrical diametric magnets are angled from horizontal and are separated by an increasing gap from respective circular ends of the at least two cylindrical diametric magnets to distal circular ends of the at least two cylindrical diametric magnets;
- and
- a diamagnetic rod within the increasing gap that is horizontally levitated by the two cylindrical diametric magnets in equilibrium state and wherein the diamagnetic rod is adapted to detect vertical motion.
A dipole line trap system comprising:
- a first axis unit, comprising:
- a first group of at least four cylindrical diametric magnets mounted in parallel around a single open region, wherein the single open region comprises a first horizonal gap between respective circular ends of a first pair of the first group of at least four cylindrical magnets and a second horizontal gap between respective circular ends of a second pair of the first group of the at least four cylindrical magnets, and wherein a length of the first horizontal gap is smaller than a length of the second horizontal gap;
- and
- a first diamagnetic object that is levitated by the first group of the at least four cylindrical magnets in the single open region and that is positioned relatively closer to the second pair of the first group of the at least four cylindrical magnets than the first pair of the first group of the at least four cylindrical magnets.
