Measurements of dipole moments and a Q-patch model of collisionally charged grains
2020
New Journal of Physics
Preserved Fulltext
Identical glass spheres of 434 ± 17 µm diameter are charged in collisions among each other. At slow speed some form dimers under microgravity and oscillate within the electrical field of a capacitor. The dipole moments deduced from these oscillations are large. They cannot be explained by the net charges measured for each grain (up to ±3 × 10 5 e) and show no significant dependence on the net charge in the given range. This requires a highly non-homogeneous charge distribution on the grain
