Abstract

An electromagnetic accelerator arrangement includes a stationary arrangement including at least one stationary primary coil, and a movable arrangement including at least one moveable secondary coil. The planes of the stationary and the moveable coils are parallel to a direction of movement of the moveable arrangement. The coils of the stationary and the movable arrangements have approximately the same coil width in the direction of movement of the moveable arrangement and transversely thereto, as well as the same coil separation in the direction of movement of the moveable arrangement. The at least one stationary primary coil includes at least two layers between which the at least one secondary coil of the movable component is movably disposed, the distance between the layers being kept small transversely to the direction of movement of the moveable arrangement.
