ADAM - Advanced DC and AC Magnetic Verification for the Lisa Mission and Beyond

Abstract

For the Laser Interferometer Space Antenna (LISA) mission to detect gravitational waves successfully, requirements exist to limit the acceleration noise due to magnetic fields at the location of the payload test masses (TMs). Apportioning the system level limits at unit level yields requirements that are challenging to verify due to their low frequency range (measuring as low as 20 uHz) and high sensitivity (<2 nT/√Hz at 1 mHz). The Advanced DC and AC Magnetic verification project (ADAM) aims to improve the current facility capability to meet the needs of LISA, building on heritage from the existing Mobile Coil Facility (MCF) upgrade and development of the AC Magnetic Field Verification Methods employed recently on the Jupiter Icy moons Explorer (JUICE) project. ADAM will also draw on heritage from the successful LISA Pathfinder (LPF) mission, while maintaining the capability of previous facilities, in order to push forward the state-of-the-art in unit level magnetic field verification.
