we propose to build a large wire chamber magnetic spectrometer at NAL to measure multi-body forward-going hadronic systems produced by n's, K's and protons up to 80 GeV/c. Specific reactions will be isolated in order to study the sand t dependences of the cross sections for peripheral processes, search for new resonant states and attempt to measure nn and Kn inelastic scattering. We propose a physics program for the spectrometer which is initially limited to those processes easiest to measure
... d which nevertheless spans a large range of strong interaction problems. Technically, the proposed spectrometer is a relatively modest extension of presently operating systems in the 10-20 GeV/c region, and does not present a challenge of uncertain magnitude to construct. Abstract The proposal as last amended, on May 1, 1972, remains the same, except for two changes. The senior personnel and their institutions are updated, as listed below. And the attached addendum is added to the proposal. The addendum adds to the experiment: a) Quasi two body reactions in which a two-body system is produced ++ at the target vertex (a t:. for example). b) Inclusive studies of two or more body correlations, for c) Some peripheral reactions of particular current interest involving Pomeron exchange. Abstract We propose to build a wire chamber magnetic spectrometer at NAL to measure multi-particle forward-going hadronic systems produced by rt!s, Kls, protons, and antiprotons up to 200 GeV. Specific reactions will be isolated in order to study the sand t dependences of the cross sections for peripheral processes, search for new resonant states, and attempt to measure rtrt and Krt inelastic scattering. The proposed physics program is initially limited to those processes easiest to measure which nevertheless span a large range of strong inter action problems. Technically, the proposed spectrometer is similar to systems already in use in the 10-20 GeV region. Its construction does not require a very large commitment of funds, nor does it represent a challenge of uncertain magnitude. This amended proposal differs from the original proposal 110 mainly in size of magnet, beam to be used, some details of instrumentation, and personnel. The section immediately following describes the changes in detail.
