Description
Energetic particles in the interplanetary medium penetrate spacecraft and
limit the efficiency of instruments placed aboard. LISA Pathfinder, the
mission of the European Space Agency for the testing of the technology that will be placed
aboard the first interferometer for gravitational wave detection in space, LISA, carried a
particle detector for proton and helium nuclei monitoring above 70 MeV/n and four magnetometers.
Cosmic-ray data were analysed between February 18th 2016 and July 3rd 2017. The characteristics and energy
dependence of forty-five short-term depressions of the galactic cosmic-ray flux were estimated.
A detailed study of a Forbush decrease dated August 2nd, 2016, associated
with the transit of an interplanetary coronal mass ejection, was also carried out.
The outcomes of the present work can be used in Monte Carlo simulations for space instrument performance estimates.
