HIGH-ENERGY CHARGED-PARTICLES IN-SPACE AT ONE ASTRONOMICAL UNIT

Single-event effects and many other spacecraft anomalies are caused by positively charged high-energy particles impinging on the vehicle and its component parts. Here, we review the current knowledge of the int erplanetary particle environment in the energy ranges that are most im portant for these effects. State-of-the-art engineering models are des cribed briefly along with comments on the future work required in this field.
