Abstract

Solar energetic particles (SEPs) pose a hazard to manned and unmanned space missions. Moreover, in LISA (Laser Interferometer Space Antenna) and its precursor mission LISA Pathfinder (LISA-PF) the free-fall test-masses are charged by galactic and solar energetic particles. This process generates spurious forces on the test masses which appears as significant levels of noise in the experiments. It was shown that relativistic solar electron detection can be used for up-to-one-hour forecasting of incoming energetic ions at 1 AU. Contemporary observations of solar electrons, protons and helium nuclei on board LISA will allow us to forecast and investigate the characteristics of SEPs over small steps in longitude.
