摘要: In a closed electron drift thruster, magnetic circuit for creating field in main annular channel comprises at least one axial core surrounded by first coil and an inner upstream pole piece forming body of revolution, together with plurality outer cores coils. The further essentially radial defining concave peripheral surface second convex surface. the present respective adjusted profiles that are distinct from circular cylindrical surfaces so as to form between them gap varying width presenting zones maximum value register coils minimum create uniform field.
