Cemented fibers as a testbed for distributed acoustic sensing (DAS)
Thomas Forbriger, Felix Münch, Laura Hillmann +6
A rigid connection between the optical fiber and the rock makes amplitudes of 'fiber strain' measured with Distributed Acoustic Sensing (DAS) equal to 'rock strain'. We demonstrate…

A numerical framework for Newtonian-noise estimation at the Einstein Telescope: 2-D simulations beyond the plane-wave approximation
Patrick Schillings, Shi Yao, Johannes Erdmann +1
The Einstein Telescope (ET) is a third-generation underground gravitational-wave observatory designed to extend the detection sensitivity down to a few Hertz. Newtonian noise is ex…

Calibration of the strain amplitude recorded with DAS using a strainmeter array
Thomas Forbriger, Nasim Karamzadeh, Jérôme Azzola +3
The power of distributed acoustic sensing (DAS) lies in its ability to sample deformation signals along an optical fiber at hundreds of locations with only one interrogation unit (…
