Type of experiment | 2 vitreous carbon spheres mounted on radial booms (42 m tip-to-tip), 2 sets of three-axis search coil magnetometers, one for the ULF/ELF range and one for the VLF range (each is mounted on the locking 3-m booms at a distance of 2 m from the spacecraft), 4 meshed spheres mounted at the end of the 2.5-m axial booms. |
