On the Performance Characteristics of Electron Ring Accelerators

Description: On the basis of our present understanding of the physical phenomena involved in an electron ring accelerator (ERA), a theoretical study is made of the performance which might be expected for an ERA. Rigorous upper bounds are obtained on the rate of energy gain, from which it is shown that, in order to prevent azimuthal instability, parameters must be selected such that (for reasonable fields, injector properties, etc., but with no safety factors) the proton energy gain is less than 80 MeV/m.

The Direct Production of Electron Pairs in Nuclear Emulsion by 100 and 200 GeV Protons

Description: It is proposed to study the direct production of electron pairs produced when a high energy proton interacts with the Coulomb field of a nucleus. This process occurs at fourth order in quantum electrodynamics. This phenomena, called trident production when the incident particle is an electron, is characterized by a single incident primary track and three emerging tracks. Accelerator experiments on direct pair production by protons have not been previously reported, due to the small cross-sectio… more

A Proposal to Study Small Angle Proton-Deuteron Scattering

Description: We propose an extension of the present p-p small angle scattering experiment to a measurement of p-d scattering using a deuterium gas jet. In 400 hours of beam time we will measure as a function of energy; (a) the slope of the small angle p-d scattering; (b) the real part of the forward p-d scattering; (c) the total p-d cross section; and (d) the coherent diffraction dissociation of protons on deuterons. No new apparatus is required or need be installed for the performance of this experiment.

A Study of Antineutrino Interactions in the NAL 15-FT Bubble Chamber, Filled wit Hydrogen and Neon

Description: A study of antineutrino interactions in the 15-ft bubble chamber filled with a neon-hydrogen mixture is proposed. This mixture provides good detection efficiency for a neutral component and lepton identification. We request a total flux of {approx} 10{sup 19} interacting protons at the highest available energy for the proposed program. Our program includes the measurement of total cross sections of antineutrino interactions, inclusive and exclusive reactions, which can be described by either ch… more

Proposal to Study Multibody Final States in pp Collisions at 200 GeV/c Using the NAL 15-Foot Bubble Chamber

Description: We propose to expose the NAL 15-foot hydrogen bubble chamber to 200 GeV protons. We intend to take 20,000 pictures. Multiparticle final states will be studied by measuring the momenta of all charged final state particles with the exception of a few very fast tracks where at least the charge and the emission angle of the particle will be determined. Comparison with various models for high energy multiparticle production will be made. Additionally, K{sup o} and {Lambda} production will be studied… more

Experiments with polarized beams and targets

Description: A lecture is given on possible experiments at the ZGS facility, and a discussion of the spin dependence of strong interactions. It is noted that the most interesting experiments will probably be studies of the differences between the various initial spin states in p + p scattering. (JFP)

The Porcupine

Description: Informal report describing a suggestion for a way to detect secondary particles produced by the collision of protons at high center-of-mass energies: The present note has as its purpose to suggest a new 4π geometry concept for detecting the reaction products, which eases some of the problems of high-multiplicity events. The device could be used as a stand-alone detector in some experiments, but basically is conceived as a useful adjunct to a calorimeter type device. I call it the Porcupine fo… more
