Modeling a calibrator for laser interferometer gravitational wave detectors

Abstract

Abstract Laser Interferometers Gravitational Wave detectors have more than 100 active attenuator systems, the normal methods for calibration seems to not work properly. This work aims to model a calibrator for this detector in the form of a resonant-mass Nb gravitational detector thar has the same sensitivity of LIGO detector bur operating in a narrow band. This detector will detect the same gravitational wave and use this signal to calibrate LIGO. A simulation in a lumped model is made and it shows that the calibration is achievable.
