As an electron source of an Electro dynamic tether system and ion engine system, a field emission cathode with cubic boron nitride (cBN) thin layer have been developed. The maximum extracted current is 107 micro A; the current density is 0.55 mA/cm^2.The influence of atomic oxygen on extracted performance was investigated at atomic oxygen injection test was conducted Atomic oxygen durability test facility in Kyushu institute of technology. The result showed that Field emission cathode with cBN has atomic oxygen tolerance.
