Abstract
A dipole arrangement which is located in a sheath,including segments of ejectable dipoles sequentially arranged within the sheath. The dipole can be ejected from the sheath within a short time interval and, subsequent to ejection, will rapidly form a large-surfaced and homogeneous cloud. The segments of the sheath which has a polished inner surface, as viewed in the ejecting direction, evidence an envelopment with a reducing number of windings which consists of a thin metal foil, smooth on both sides thereof, and wherein the dipoles of the enveloped segments, or the only partially enveloped segments, are centripetally pretensioned. The dipoles which are prestressed in the segments act as drive springs for the metal foil which encompass the segment whereby, dependent upon the winding number of the metal foil, there is achieved a time-delayed release of the dipoles.
