Abstract
A fast second level trigger has been developed for the ARGUS experimen t which recognizes tracks originating from the interaction region. The processor compares the hits in the ARGUS micro vertex drift chamber t o 245 760 masks stored in random access memories. The masks which are fully defined in three dimensions are able to reject tracks originatin g in the wall of the narrow beampipe of 10.5 mm radius.
