A number of major new accelerator facilities, which have shaped the activities of many physicists for the better part of a decade: SLC, LEP, HERA, has been completed. The new generation of high-luminosity pp supercolliders, LHC, SSC and Eloisatron (ELN), represents the great challenge of subnuclear physics. In this challenge the crucial problem is the design of a superdetector. It is clear that building the detectors will be the bottleneck for the Supercolliders. The CERN-LAA project is a concerted effort to solve the problems imposed by the harsh experimental conditions, under which the new physics has to be studied. It is conceptually and practically a unique effort. This Workshop brought together the physicists working on the LAA project and their reports are found in this volume.
