    • Capacitive sensing of test mass motion with nanometer precision over millimeter-wide sensing gaps for space-borne gravitational reference sensors 

      Audley, H.; Auger, G.; Baird, J.; Binetruy, P.; Caleno, M.; Cesarini, A.; Diepholz, I; Dixon, G; Dolesi, R; Ferraioli, L.; Heinzel, G; Hollington, D.; Karnesis, N.; Martín-Porqueras, F.; Fernandez Sopuerta, Carlos; Texier, D.; Vitale, S.; Wanner, G; Ward, Harold; Ramos Castro, Juan José (2017-09-26)
      Article
      Open Access
      We report on the performance of the capacitive gap-sensing system of the Gravitational Reference Sensor on board the LISA Pathfinder spacecraft. From in-flight measurements, the system has demonstrated a performance, down ...
    • Charge-induced force noise on free-falling test masses: results from LISA pathfinder 

      Armano, M.; Audley, H.; Auger, G.; Baird, J.; Binetruy, P.; Ramos Castro, Juan José (2017-04-26)
      Article
      Open Access
      We report on electrostatic measurements made on board the European Space Agency mission LISA Pathfinder. Detailed measurements of the charge-induced electrostatic forces exerted on free-falling test masses (TMs) inside the ...
    • Constraints on LISA pathfinder's self-gravity: design requirements, estimates and testing procedures 

      Armano, M.; Audley, H.; Auger, G.; Baird, J.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Brandt, N.; Bursi, A.; Caleno, M.; Cavalleri, A.; Cesarini, A.; Cruise, M.; Danzmann, K.; Ramos Castro, Juan José (2016-11-08)
      Article
      Open Access
      LISA Pathfinder satellite was launched on 3 December 2015 toward the Sun–Earth first Lagrangian point (L1) where the LISA Technology Package (LTP), which is the main science payload, will be tested. LTP achieves measurements ...
    • Sub-Femto-g free fall for space-based gravitational wave observatories : LISA Pathfinder results 

      Armano, M.; Audley, H.; Auger, G.; Nofrarias Serra, Miquel; Sanjuán Muñoz, Josep; Ramos Castro, Juan José (2016-06-07)
      Article
      Open Access
      We report the first results of the LISA Pathfinder in-flight experiment. The results demonstrate that two free-falling reference test masses, such as those needed for a space-based gravitational wave observatory like LISA, ...
