Abstract : A preliminary assessment of the radiation hardness of the electronics subsystem of the Fairchild pulsed plasma thruster is presented. Both the natural and artificial radiation environment in space are considered. The total dose and transient effects of high-energy electrons, gamma rays, x-rays, neutrons and electromagnetic pulsed are reviewed for various types of solid-state devices, including transistors, diodes, SCRs, integrated circuits, resistors and capacitors. Recommendations are made for component choices, circuit designs, shielding and testing to minimize long term degradation and circuit upsets from space radiation. (Author)
