DOWNLOAD EBOOKWe propose here to take 50,000 pictures of the NAL 30-inch bubble chamber, filled with hydrogen and exposed to 200 GeV/c beams of negative pions. We intend to study the technical limitations of the use of a bubble chamber for such high energy interactions. At the same time we will investigate the physics contained in the pictures as much as and as soon as possible. We expect to finish the study made only by scanning in a month and to end all studies in six months after getting film. Even in the energy of 200 GeV region, interactions will be accompanied with some slow secondary particles, which will be the object of analysis most interest. However majority of interactions may have a jet like topology. We will mainly use our FSD for the analysis of this experiment and the accuracy in momentum measurement and the separation of each track in a condensed jet may be the main subjects of our technical study. In the 30-inch bubble chamber, we propose to insert a target plate and a gamma conversion plate, if the situation of the chamber will allow to do so. A short discussion for the insertion of plates will be shown later.

DOWNLOAD EBOOKAn investigation of 281 interactions of 2 GeV/c negative pions with emulsion nuclei is reported. The fraction of stars with charged secondary pions is 75=3 per cent, and the mean number per star of emitted charged pions is 1.21 =0.08. Only 2 K-mesons have been observed, which confirms other results that the production cross section of strange particles is low. Our results have been compared with the predictions from a cascade calculation by Metropolis et al. which starts from the known elementary pion-nucleon and nucleon-nucleon cross sections. The agreement between the calculated data and our experimental results is good as far as the multiplicity, energy spectrum and angular distribution of emitted pions and also the energy spectrum of knockon protons are concerned.
