Method for passive/active superconducting vibration isolation

Disclosed is a method for passive/active superconducting vibration isolation. Benefits include improved functionality and improved cost effectiveness.

Description

              The disclosed method provides passive/active superconducting vibration isolation. The method applies to an application where vibration cannot be tolerated (see Figure 1).

              The key elements of the disclosed method include:

•             Piezoelectric device to detect and measure vibration waves (A piezoelectric device responds passively to vibration compression waves.)

•             Active electromagnet to oppose the superconductor

•             Circuitry to amplify and transmit a signal from the piezoelectric device to an active electromagnet

•             Bulk large single-domain YBa2Cu3Oxide high-temperature superconductor in the mixed Meisner state to provide pinning and exactly oppose a magnetic field (The superconductor responds passively to a magnetic field.)

•             Cryogenic system to maintain the superconductor in a mixed Meisner state (see Figure 2)

Advantages

              The disclosed method provides advantages, including:
•             Improved functionality due to enabling the isolation of individual tools or components on tools

•             Improved cost effectiveness due to eliminating the requirement for an isolation pad for the entire superconductor facility
