ION PROPULSION WORKING FLUID REQUIREMENTS FOR USAF

Abstract

Some of the anticipated requirements for ion engine working fluids are derived by the consideration of missions expected to be of interest, the probable systems which will produce the power, and handling needs. Summary of requirements: (1) high mass-to-charge ratio (about 2000 AMU singly ionized); (2) one ion species; (3) Liquefaction somewhere between 0 - 600 C; (4) vaporization under 1000 C; (5) low energy of ionization; (6) compatibility with normal lightweight structural materials; (7) lack of toxicity is convenient; (8) stability to radiation; (9) some easy method of ionization; (10) easy desorption from some high work function material; and (11) non-fragmentation.
