In this paper we discuss the status of technology for achieving free fall of test-masses for LISA. The main part of this effort consists of developing an inertial sensor with parasitic force isolation better than 10[sup -15] N/&sqrt;Hz at 0.1 mHz, and residual coupling of test-mass to spacecraft with stiffness less than 10[sup -7] N/m. We also briefly report on experiments to test sensor performances on ground and in space. © 2000 American Institute of Physics.

    This paper presents design of micro stage performing 6 degree-of-freedom (DOF) motions, which actuated by voice coil motor (VCM). The VCMs generate forces to perform in-plane motions and out-of-plane motions. The stage is supported by springs for compensating mass of the moving part of the stage...
