Hybrid bubble chamber studies of K+ p and K- p interactions at 75-GeV/c
We propose to expose the FNAL 30' liquid hydrogen bubble chamber to K{sup +} and K{sup -} beams both at 75 GeV/c. Each exposure consists of 100,000 equivalent K pictures. We plan to use the upstream tagging system currently in place and a downstream spectrometer with acceptance considerably increased over that of the current PHC system. This new downstream system will also be equipped with a lead glass photon detector with good spatial and energy resolution. We will study comparison of K{sup +} and K{sup -} results, as well as results from {pi}{sup +}, {pi}{sup -} , and {bar p} beams at this energy which are the subject of separate proposals

Hybrid bubble chamber study of anti-p p interactions at 75-GeV/c
We propose a careful study of antiproton-proton interactions at 75 GeV/c in the Fermilab 30' hybrid bubble chamber. An exposure of 300K pictures is requested to provide 50K interactions of which approximately 7K are annihilation events. Using the properties of this system which is very well matched to the often complex topologies associated with annihilations and to this beam momentum, we plan to study all experimentally accessible features. In particular, single and multi-particle inclusive distributions for charged and neutrals will be measured, exclusive fits will be made where possible, new particles will be searched for, and comparisons made to other energies and to other beam particles

pi+ p Interactions at 250-GeV/c in improved FNAL 30 inch hybrid system
We propose to utilize the excellent momentum resolution, increased angular acceptance, and neutral particle detection capabilities of the improved FNAL 30' hybrid bubble chamber system to study interaction of 250 GeV/c {pi}{sup +} mesons in an enriched {pi}{sup +(l)} beam. We will examine leading particle effects and diffraction dissociation, long and short range correlations, inclusive single particle and resonance production, strange particle production, and systematics of events with forward {pi}{sup 0} and {eta}{sup 0}. Comparison with Experiment 299 results and a proposed experiment at 75 GeV/c will permit determination of general energy dependence of these effects, particularly leading particle cross section where-good resolution near x = 1 is essential to test carefully model dependent predictions of leading particle cross sections
