Other Versions:
Various tests were performed on a UHV-compatible prototype tiltmeter balanced on a knife-edge blade. The tiltmeter is intended for potential use in LIGO detectors to measure seismic disturbances. Aspects such as the resonant frequency, hysteresis, and noise were changed and analyzed.
