Laser interferometer space antenna (LISA) is the first interferometer devoted to the detection of low frequency gravitational waves in space.

Abstract
Laser interferometer space antenna (LISA) is the first interferometer devoted to the detection of low frequency gravitational waves in space. Control of the environment and the study of the effects of energetic particles traversing the LISA apparatus are mandatory for this experiment to be fully successful. Telescopes for solar and cosmic-ray particle monitoring will be placed on board LISA and its precursor mission LISA Pathfinder (LISA-PF). In particular, proton, helium and electron detection is recommended on LISA. In this paper, we report expected incident galactic proton and helium fluxes at the time of LISA and LISA-PF missions. The number of solar events with the fluence ranging between 106 and 1011 protons cm−2 above 30 MeV occurring during the LISA missions is estimated as well. Finally, we discuss the importance of electron detection on LISA to forecast upcoming solar energetic protons.
