Notes:
Ultrasensitive accelerometers with electrostatic suspension use a technology allowing operation at ambient temperature. However, their resolution is theoretically limited to around 10−12 m s−2/Hz1/2 by thermal noise. To overcome this limit, and in the perspective of future space missions, an electrostatic sensor compatible with operation at cryogenic temperatures is currently under development. It should ultimately reduce thermodynamic noise and improve the instrument characteristics. The perspectives for a rectangular proof mass electrostatically suspended with six degrees of freedom at liquid-helium temperature are presented and discussed, as are tests and test data. © 2002 American Institute of Physics.
