Study of proton induced nuclear fragmentation in the threshold region: 1 to 20 GeV
This thesis contains the details of the experimental set-up and final results of BNL E-778. The experimental objective was to study proton induced nuclear fragmentation using an internal gas jet target facility that was specifically designed for this experiment and installed in the AGS main ring. The fragment telescopes were designed to measure a broad range of fragment charge (2 to 14) and kinetic energy (5 to 100 MeV). Using a mixed gas target (1% or 3% Xe with H/sub 2/), normalized fragment production cross sections were obtained by separately measuring p-p elastic production from the H/sub 2/ component. Fragment production cross sections are observed to rise dramatically (approx.x10) for incident proton energies between 1 and 10 GeV, while above 10 GeV, fragment production appears to be independent of the incident proton energy. The measured differential cross sections (above 10 GeV0 are found to agree (within 20%) with the differential cross sections measured during a previous internal target experiment (E-591) conducted at FNAL, where the lowest available proton energies were 50 GeV.
