Lunar Dust EXplorer (LDEX) on LADEE

LDEX is an impact ionization dust detector with a sensor area of ~ 0.01 m2, derived from the heritage of the dust instruments operating on HEOS 2, Galileo, Ulysses, and Cassini. In addition to individual dust impacts of grains with radii rg > 0.3μm, LDEX can identify a large population of smaller grains (0.1 < rg < 0.3 μm) by measuring their collective signal.
