Sensor Noise in $LISA$ $Pathfinder$ : In-Flight Performance of the Optical Test Mass Readout

Armano, M. Audley, H. Baird, J.

We report on the first subpicometer interferometer flown in space. It was part of ESA's Laser Interferometer Space Antenna (LISA) Pathfinder mission and performed the fundamental measurement of the positional and angular motion of two free-falling test masses. The interferometer worked immediately, stably, and reliably from switch on until the...

Sensor noise in LISA Pathfinder: An extensive in-flight review of the angular and longitudinal interferometric measurement system

Armano, M. Audley, H. Baird, J.

In a previous article [1], we have reported on the first subpicometer interferometer flown in space as part of ESA's LISA Pathfinder mission, and have shown the residual sensor noise to be on the level of $32.0^{+2.4}_{-1.7}$ fm/$\sqrt{\textrm{Hz}}$. This review provides a deeper and more complete overview of the full system and its...
