An experimental program to study the interactions of hadrons and photons is being carried out using hybrid systems which include bubble chambers as visible targets as well as counter spectrometers for particle detection, measurement and identification. Experiments are now being carried out at Fermilab and SLAC, and additional experiments have been approved for the Tevatron at Fermilab and for the SPS at CERN. During the late winter and spring of 1982, we completed our run at Fermilab for the study of ..pi../sup + -/, K/sup +/ and p interactions in hydrogen and in magnesium, silver and gold, at a beam momentum of 200 GeV/c (FNAL Experiments E-565 and E-570). A total of just over one million pictures has been obtained. A preliminary analysis of the multiplicity distributions as a function of atomic number A has been done. Successful running has continued with the Stanford Hybrid Facility in a polarized monoenergetic photon beam of 20 GeV/c (SLAC Experiments BC-72/73). Results have been obtained on the photoproduction of charm, and on the life times of charmed particles, and analysis is in progress also on other topics, including production of vector mesons, strange particles, and the ..delta../sup + +/ resonance. Extensive work continues on the analysis of our earlier FNAL experiment on ..pi../sup +/p, K/sup +/p and PP interactions at 147 GeV/c (FNAL Experiment E-299). Phase 1 approval has been received for an experiment (FNAL E-636) to be carried out at the Tevatron when it comes into operation at Fermilab. This experiment is designed to study neutrino interactions and the production of tau neutrinos, using a neutrino beam produced by beam dump techniques and employing a hybrid system with a holographic bubble chamber.
