The LISA gravitational wave observatory requires free-falling test masses that serve as references of geodesic motion to within a residual stray acceleration of 3 fm/s2 /pHz at frequencies above 0.1 mHz. The LISA Pathfinder (LPF) mission is dedicated to demonstrating the technology of free-falling test masses at a level close to the LISA goal. This article addresses the experimentally-based performance analysis for the LPF measurement of differential test mass acceleration noise, including a discussion of the applicability of the LPF results to the LISA mission.

Abstract
The LISA gravitational wave observatory requires free-falling test masses that serve as references of geodesic motion to within a residual stray acceleration of 3 fm/s2 /pHz at frequencies above 0.1 mHz. The LISA Pathfinder (LPF) mission is dedicated to demonstrating the technology of free-falling test masses at a level close to the LISA goal. This article addresses the experimentally-based performance analysis for the LPF measurement of differential test mass acceleration noise, including a discussion of the applicability of the LPF results to the LISA mission.File in questo prodotto:
