Abstract
According to an embodiment, an ion pump for use in a low gravity environment includes a housing at least partially defining a pumping chamber, the pumping chamber enclosing a first cathode plate and a second cathode plate, and a plurality of cylindrical anodes disposed between the first cathode plate and the second cathode plate. The ion pump also includes a feedthrough extending external to the pumping chamber from a wall of the housing, and a baffle including a body disposed in a space between the plurality of anodes and an inner surface of the wall. The body has dimensions selected to prevent particles having a size greater than a selected particle size from migrating from the pumping chamber to the feedthrough when in the low gravity environment.
