Characterization of rock vibrations at the Homestake mine - The laboratory

The instruments and the data acquisition are controlled remotely from our lab which is inside the Ross dry. Also, the data is regularly transmitted to our lab where we can start to analyze it. In the near future, we will have access to this system from any place in the world, so that we and our coll…

Characterization of rock vibrations at the Homestake mine - The Seismic Stations

At each station, one rigid-foam panel hut houses the sensors, whereas a second hut houses a computer and a power supply. The sensor hut serves as shield againstacoustic noise and water.

Characterization of rock vibrations at the Homestake mine - Our first steps at Homestake

Our experiments at Homestake are determined by two main goals:1. We want to characterize seismic noise and rock density fluctuations in an underground environment.2. We want to assess the quality of the Homestake mine as a candidate for a third generation underground gravitational-wave detector. As …

Characterization of rock vibrations at the Homestake mine - Gravitational-wave detection

Physicists describe a gravitational wave as an oscillatory disturbance of spacetime. For most purposes, it can be understood as a force field traveling at the speed of light which changes distances between free masses. A gravitational-wave detector has to monitor these changes. The LIGO scientific c…
