Engineering model electrostatic sensing and forcing electronics developed for the LISA Pathfinder gravitational reference sensor (GRS) obtain measured displacement sensitivity δx ∼ 1.5×10−9 m Hz −1/2 to below f ⩽ 0.1×10−3 Hz with 30 Vdc fields when needed for proof‐mass initialization and charge measurement, while DC bias trim provides work‐function nulling to ± 50 mV with < 2mV step resolution and stability δV < 8×10−6 V Hz −1/2. Results are consistent with LISA noise models for electrostatic sensing, forcing, and DC nulling. |
