Abstract
An ionic liquid ion source can include a microfabricated body including a base and a tip. The body can be formed of a porous material compatible with at least one of an ionic liquid or room-temperature molten salt. The body can have a pore size gradient that decreases from the base of the body to the tip of the body, such that the at least one of an ionic liquid or room-temperature molten salt is capable of being transported through capillarity from the base to the tip.
Claims20
A system for producing ions comprising:
- a source of ions;
- a first porous material in contact with the source of ions;
- a connecting member comprising a second porous material, wherein the connecting member is operatively coupled to the first porous material;
- and
- an array of emitters comprising a third porous material, wherein the array is operatively coupled to the connecting member, wherein the source of ions is transported through capillarity from the first porous material to the array of emitters through the connecting member.
