Design and evaluation of a simple ultralow vibration vacuum environment

Abstract: A vibration-isolated platform in a high-vacuum environment designed for prototyping optical interferometers is described. The system provides isolation from both seismic and acoustic disturbances with a residual acceleration of 2.9×10−6 m/s2 rms (root-mean-square) in the vertical direction and 6.3×10−6 m/s2 rms in the horizontal in the bandwidth from 5 to 400 Hz. The environmental decoupling provided by the spring suspension, air-spring table legs, and vacuum are evaluated sequentially to illustrate the effect… Show more

“…Lawall and Kessler consider low cost and easy of use to design a vacuum chamber for testing optical interferometers. 12 Ultra high vacuum is needed to completely isolate the test from acoustic waves from the outside. They use a combination of an air-spring table, a vacuum bellows, and a suspended turbo pump configuration to exceedingly reduce vibration input to the chamber over a frequency range of 0.25-3 kHz.…”
