Estimate of force noise from electrostatic patch potentials in LISA Pathfinder

Ferroni, V.; Sala, L.; Vitale, S. +1 more

This paper discusses force noise in LISA and LISA Pathfinder arising from the interaction of patch potentials on the test mass and surrounding electrode housing surfaces with their own temporal fluctuations. We aim to estimate the contribution of this phenomenon to the force noise detected in LISA Pathfinder in excess of the background from Browni…
