COLLECTIVE PHENOMENA IN ACCELERATORS

Description: Recent years have witnessed the development of accelerators of ever-larger current, both peak and average, as well as a proliferation of storage rings of ever-greater luminosity. Consequently, there is considerable interest in and growing concern with, the phenomena which limit beam currents and beam densities, namely, the collective modes of behavior of relativistic particle beams. Furthermore, it has been demonstrated that the collective behavior can be controlled, at least to some extent, tu… more

Proposal for an Experiment at the National Accelerator Laboratory Nuclear Levels as Analyzers of High Energy Interactions

Description: We propose to study diffractive phenomena caused by 100 BeV pions, using a new technique, which consists in associating with the high energy interaction, the detection of photons resulting from the de-excitation of nuclear levels. Knowledge of the quantum numbers both for the ground state and the nuclear levels of the nuclei used, adds information as to the type of interaction. In particular, the use of the 4.4 MeV level of Carbon guarantees that the exchange quantum has isotopic spin 0. In add… more

K+ p Multiparticle Production in the 30" NAL Hybrid Chamber at the Highest Possible Energy

Description: One of the unique features of NAL that cannot be duplicated elsewhere (i.e. at CERN-ISR) is the ability to make high energy neutrino beams and high energy meson beams, It appears that meson-proton interactions may have given us some insight into hadron structure because the asymmetry (2 quarks on 3) which one observes in them cannot be seen in proton-proton (3 quarks on 3) interactions. Although the asymmetry can be observed in {pi} p collisions, it is likely that more can be learned if the rol… more

Proposal to Study Electroproduction with Coincidence Techniques at High Energies

Description: Using the large aperture spectrometer of proposal 144 and the electron beam with the tagging system removed we propose to study deep inelastic electron scattering at incident electron energies between 50 and 150 GeV, for values of q{sup 2} between 1 and 20 Gev{sup 2}/c and {nu} between 10 and 130 GeV. The spectrometer will detect not only the scattered electron but also most of the secondary particles.

NAL Proposal for Study of Photons and Leptons Produced in Meson-Nucleon Collisions in the Deep Scattering Region; Search for Intermediate Bosons, Heavy Leptons, Anomalous Hadronic Processes and Study of Multi-Gamma-Ray Final States

Description: We propose to observe gamma rays and leptons carrying high transverse momentum, in pairs or singles, emerging from meson-nucleon collisions at high energies. These meson-nucleon collisions probe the constituent structure of nucleons and reveal anomalous hadronic interaction processes at small distances. We will search for structure in the effective mass continuum of various (wide angle) pair combinations and in the transverse momentum spectra of singles and pairs. An experimental sensitivity co… more

Stress-induced deformation of metals during fast-neutron irradiation

Description: From European conference on irradiation embrittlement and creep in fuel cladding and core components; London, UK (9 Nov Theoretical models for the deformation of metals subjected simultaneously to external loads and fast-neutron irradiation are discussed. The following models have been analyzed in detail: dislocation climb; climb controlled glide; and nucleation, growth, and unfaulting of dislocation loops. It is shown that the strains produced only by the climb of dislocations are equal to the… 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)
