Book excerpt: We 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.
