Simulating the charging of isolated free-falling masses from TeV to eV energies: detailed comparison with LISA Pathfinder results
P. J. Wass, T. J. Sumner, H. M Araújo +1
A model is presented that explains the charging rate of the LISA Pathfinder test masses by the interplanetary cosmic ray environment. The model incorporates particle-tracking from…
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…
Transient acceleration events in LISA Pathfinder data: properties and possible physical origin
LISA Pathfinder Collaboration
We present an in depth analysis of the transient events, or glitches, detected at a rate of about one per day in the differential acceleration data of LISA Pathfinder. We show that…
New LISA dynamics feedback control scheme: Common-mode isolation of test mass control and probes of test-mass acceleration
Henri Inchauspé, Martin Hewitson, Orion Sauter +1
The Drag-Free and Attitude Control System is a central element of LISA technology, ensuring the very high dynamic stability of spacecraft and test masses required in order to reach…
