N2 - Galactic cosmic rays (GCRs) and solar particles of energies > 100 MeV/n penetrate and charge the test-masses of the Lisa Pathfinder (LISA-PF) mission. LISA-PF is the technology testing mission of eLISA/NGO, the first interferometer devoted to gravitational wave detection in space. Radiation monitors will be placed on board LISA-PF for GCR and solar energetic particle (SEP) flux measurements above a few tens of MeV/n. Here we show that, despite the limited capabilities of these particle detectors, we will be able to estimate the test-mass charging process at the occurrence of SEP events of any intensity. In this respect, we have simulated the radiation monitor performance during the strong SEP event of 23 February 1956 with the Fluka Monte Carlo package. SEP energy and spatial distributions during the event evolution were considered. The results of this work can be extended to other space missions carrying devices for SEP detection.
