Description

We are in the process of developing a detector that is capable of measuring the movement of a test mass with a spatial resolution of 10’s of nanometers and a temporal resolution of a few nanoseconds. This detector will be used in future experiments that will examine weakly coupled oscillators. Essentially, the detector consists of a Michelson interferometer with the mirror for one arm mounted on the test mass. A fast photodiode is used to measure changes in the interference pattern as the test mass moves. In this presentation, we will detail, and explain, the design of the detector, as well as providing a status of its current capabilities.
