Presentation Transcript

  1. New Ideas, Concepts, Designs • New suspensions • Non-traditional displacement transducers • Miscellany • Questions

  2. New suspensions • MEMS Seismometer • Electrochemical • Superconducting • Magnetic levitation • Ferro-fluid suspension • Quartz non-magnetic • Folded pendulum • Free-fall (atomic fountain)

  3. Non-traditional displacement transducers • Electrochemical • Correlated double sampling • 500 MHz capacitive sensor • SQUID • Optical

  4. Miscellany • Laser ring gyro • Rotation sensors to correct for tilt • LIGO strainmeter • SLAC strainmeter

  5. Questions • What is state of the art in finite-element modeling of mass-spring system? • What new materials are available? • What existing materials are becoming unavailable? • What are costs and sensitivities of ideas above?

  6. Our group plans to reconvene to assign sensitivities and costs following this session
