Matter-Wave Interferometry Vibration Isolation

Abstract

This note provides a brief summary of vibration isolation techniques and their application to our neutral atom interferometry experiments. Naturally, the difficulty in achieving acceptable vibration isolation for any given experiment depends largely upon the noise background of the laboratory, the noise generated by the experimental apparatus itself, as well as the tolerable noise sensitivity of the experiment. Since neutral atom interferometers may be configured to act as ultra-sensitive inertial sensors, their vibrational noise sensitivity is inherently high. The initial experiments are to simply demonstrate neutral atom interference. For these experiments any deviations from an inertial reference frame for the apparatus represent a potential noise source. Even the quasi-constant earth's gravitational field and rotation can be considered as very low frequency noise components, although subsequent experiments will consider these as known test signal's to be measured.
