Compensation of gravity on cold atoms by a linear optical potential

open access: yesPhysical Review Research, 2020
We demonstrate gravity compensation for an ultracold gas of ^{87}Rb atoms with a time-averaged optical potential. The position of a far-off-resonance beam is temporally modulated with an acousto-optic deflector to efficiently produce a potential with a ...

A Gravity Compensation Strategy for On-ground Validation of Orbital Manipulators [PDF]

open access: yes, 2023
The on-ground validation of orbital manipulators is a challenging task because the robot is designed for a gravity-free operational environment, but it is validated under the effect of gravity.

Passive Limitations for a Magnetic Gravity Compensator

open access: yesJournal of System Design and Dynamics, 2009
The development of sophisticated advanced vibration isolation is important because even the minutest vibrations have disastrous effects on the performance of static and moving parts in high-precision machines. This paper concerns with the isolation of these vibrations for a large static body in an advanced micro-lithographic system, where a passive ...

Limitation on the Use of the Horizontal Clinostat as a Gravity Compensator [PDF]

open access: yesPlant Physiology, 1976
If the horizontal clinostat effectively compensates for the influence of the gravity vector on the rotating plant, it should make the plant unresponsive to whatever chronic acceleration may be applied transverse to the axis of clinostat rotation. This was tested by centrifuging plants while they were growing on clinostats. For a number of morphological
