Processes of energy deposition by heavy particle impact. Technical report No. 2

Description: Experimental studies of the Li/sup +/ + He interaction have been extended to smaller internuclear separations to clarify a discrepancy between experiment and theory in the elastic cross sections and to observe and measure cross sections for inelastic excitation. For R less than or equal to 0.5 a/sub 0/ the elastic scattering differential cross section is observed to droop far below that expected from a single-state interaction based on ab initio ground-state potentials. In this same region of R… more

Safety Test Program Summary SNAP 19 Pioneer Heat Source Safety Program

Description: Sixteen heat source assemblies have been tested in support of the SNAP 19 Pioneer Safety Test Program. Seven were subjected to simulated reentry heating in various plasma arc facilities followed by impact on earth or granite. Six assemblies were tested under abort accident conditions of overpressure, shrapnel impact, and solid and liquid propellant fires. Three capsules were hot impacted under Transit capsule impact conditions to verify comparability of test results between the two similar caps… more

Proposal to study neutrino interactions in the 30 m**3 NAL bubble chamber with muon identifier

Description: We propose to study high-energy neutrino intersections in the NAL 30 m{sup 3} bubble chamber. A slight alteration of the chamber design will allow a large-solid-angle quantameter to be placed just outside the thin (1/2 inch steel) wall of the bubble chamber. A detector, designed to identify the muon of the interaction is placed outside the vacuum tank. With this hybrid system they can reconstruct the neutrino's energy, the lepton momentum transfer squared, Q{sup 2}, the lepton energy transfer a… more

Measurements of elastic and quasi-elastic scatterings of pp and -pp from ~ 20 to 40 GeV/c

Description: We propose a systematic study of elastic and quasi-elastic scatterings of pp and {bar p}p in the forward region (|t{vert_bar} {approx}< 1.5 GeV{sup 2}) from {approx} 20 to 40 GeV/c by using the single-arm spectrometer of NAL Exp. 7 without any essential change. The physics interests in this energy region warrant a precise comparison between pp and {bar p}p as a function of s(t) for fixed t(s). Therefore it is essential to use the same experimental apparatus and analysis procedures in order t… more

Negative Pion - Proton Interactions at 200 GeV/c

Description: 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… more

Preliminary Proposal to Study Neutrino Interactions with Neutrons and Protons Using the 15-Foot Bubble Chamber at NAL Filled with Deuterium

Description: We propose an investigation of neutrino interactions in the deuterium filled 15-foot bubble chamber at NAL. A 250,000 picture run with 200 GeV protons should yield very interesting physics even with a 'bare' deuterium chamber. This addendum extends the physics discussion in the original proposal to the search for charm particles, and the study of neutral currents. A ({nu}{sub {mu}},d) bubble chamber exposure with E{sub P} = 200-300 GeV is the most promising experiment that can be done to search… more

Proposal to Build an Electron-Photon Facility at NAL and to Measure Photon Scattering at High Energies

Description: The National Accelerator Laboratory opens up a new era in our search of what elementary particles are like; the 100-500 GeV era. If we want to look at the structure of hadrons with the resolution provided by the wavelength of such high energy beams, what can be more natural, to paraphrase Bjorken, than looking at them, i.e. shining light at them and watching for scattering or absorption? This is precisely what we propose to do in the experiments suggested here. Photons, real and virtual, have c… more
