ABSTRACT:
A particle trap has a cover cap which dielectrically shields a shielding area by way of a shielding surface. The shielding surface has a concave curvature. Transversely to the concave curvature, the shielding surface has surface regions which are inclined transversely to the concave curvature in the region of a trough of the concave curvature.
