Charging of free-falling test masses in orbit due to cosmic rays: results from LISA Pathfinder
LISA Pathfinder Collaboration, M. Armano, H. Audley +72
A comprehensive summary of the measurements made to characterize test mass charging due to the space environment during the LISA Pathfinder mission is presented. Measurements of th…
Precision Charge Control for Isolated Free-Falling Test Masses: LISA Pathfinder Results
M. Armano, H. Audley, J. Baird +82
The LISA Pathfinder charge management device was responsible for neutralising the cosmic ray induced electric charge that inevitably accumulated on the free-falling test masses at…
Characteristics and energy dependence of recurrent galactic cosmic-ray flux depressions and of a Forbush decrease with LISA Pathfinder
M. Armano, H. Audley, J. Baird +82
Galactic cosmic-ray (GCR) energy spectra observed in the inner heliosphere are modulated by the solar activity, the solar polarity and structures of solar and interplanetary origin…
In-depth analysis of LISA Pathfinder performance results: Time evolution, noise projection, physical models, and implications for LISA
M. Armano, H. Audley, J. Baird +77
We present an in-depth analysis of the LISA Pathfinder differential acceleration performance over the entire course of its science operations, spanning approximately 500 days. We f…
Forbush decreases and 2-day GCR flux non-recurrent variations studied with LISA Pathfinder
C. Grimani, M. Armano, H. Audley +82
Non-recurrent short term variations of the galactic cosmic-ray (GCR) flux above 70 MeV n were observed between 2016 February 18 and 2017 July 3 aboard the European Space Age…
Charge-induced force-noise on free-falling test masses: results from LISA Pathfinder
M. Armano, H. Audley, G. Auger +91
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…
