able to additional collaborators, who might join this effort at a later time. We also note that a set of four drift chambers may exist by the time of our. experimental set-up. As was noted before, the new ~erenkov counter may be the only new equipment to be assembled. Given the resources available to this group, such a system can be assembled and tested withi~ one year, We are proceeding on this basis. A major question one may face centers around the decision to conduct further muon experiment.s in light of the highly publicized CERN SPS ~-beam to be commissioned in 1978. The CERN ~-experiment is designed to study either single particle inclusive channels (Rubbia) or exclusive channel (Gabathuler-Brasse). No current plan is known for a search of jets using calorimeters and ~-stiffener proposed here. The event rate of this experiment is such that higher beam intensity is not an elementary necessity. Finally this experiment is complementary to investigations that w"ill be done by the muon experiment conducted down stream. In that experiment, the main purpose is to investigate multi muon production mechanisms. Therefore we are confident that our proposal is a unique and a highly topical search of new phenomena in deep inelastic collisions, irregardless of the status of the CERN ~-program and other approved muon experiments. We can start mounting during the next fiscal year immediately after other scheduled experiments using the muon facility are fully completed. Installation of new detectors will take 3-4 months. Data taking takes about two months (
