Trigger systems which could operate at a luminosity of 10/sup 33 cm(-2) to sec/sup -1

The possibility of a trigger system which could operate at a luminosity of 1x10 to the 33rd power/square cm sec was examined. Two luminosity related problems were stressed: the fast trigger decisions which must be made because of the high interaction rate, and the effect of multiple interactions within the integration time of the detector. The system presented while not necessarily optimal will work. It is a multi-level trigger system, where the number of events which are retained at any level is only limited by the requirement that the deadtime at the next level not be excessive. Before describing the overall system, multiple event pile up, tracking, electron identification and transverse momentum imbalance are described.
