Determination of the angular distribution of cosmic rays at sea level
… is setup in order to measure the zenith angular distribution of cosmic ray muons at sea level. The setup consists of two long scintillator counters with double-ended readout. Previous measurements have shown that the intensity of muons obey the cos 2 0 distribution. In this thesis, two …

Measurement of the differential angular distribution of the W boson produced in association with jets in proton-antiproton collisions at sqrt (s)= 1.8 TeV
… unpolarized cross section we end up with eight angular coefficients (A0 - A7), which describe theW decay distribution. At low W transverse momentum, only one of the angular coefficients is non-zero. In order to study all the coefficients, we need to study the production of the W at high …

Measurement of the Differential Angular Distribution of the W Boson Produced in Association With Jets in Proton -Antiproton Collisions at Center of Mass Energy = 1.8 TeV
… present the Standard Model prediction for the W angular coefficients Ai as a function of pWT , using a W+jet Monte Carlo event generator, which includes gluon loops. The prediction for three of the angular coefficients (A1, A4 and A6) is presented for the first time.

Diagnostics for ionized physical vapor deposition chambers
… ion flux from a magnetron discharge has a narrow angular distribution and this distribution is becoming more significant as the aspect ratio increases. In order to confirm and adjust this predicted distribution a sensor to measure angular distribution of ions in an industrial scale chamber is …

Photon scattering from 40Ca and 39K up to 14 MeV
… MeV was assumed to be due to a single line, and angular distribution and resonant absorption experiments were done on it. Nuclear resonance fluorescence was measured up to 9.5 MeV in both 39K and 40Ca using a Ge(Li) detector. Elastic scattering was seen from twelve levels in 40Ca and from …

An absolute measurement of the photodisintegration differential cross section of the deutron
We have measured the absolute 2H( 1 ,p )n angular distribution using the Illinois LASA detector at the Saskatchewan Accelerator Laboratory's tagged photon facility. Using 40 to 90 MeV photons, we aimed to measure the differential cross section with a statistical precision of typically 5% in angular …

Impact of nuclear data libraries for criticality calculation of HTGR
… C-12 elastic scattering cross section, and angular distribution of C-12 elastic scattering. For the HTTR, compared with the nominal case (all ENDF/B-VIII.1), using C-12 capture cross section data from JENDL-5 causes Δk≈−180 pcm. The difference in thermal region dominates criticality …

Tailoring the angular and spectral reflectance characteristics of color-dynamic films by modifying their photonic texture and topcoat roughness
… structure affects the spectral signature and angular distribution of reflected light. Surface roughness of the topcoat affects the angular distribution of incident and reflected light. Fourier optics concepts are harnessed for modeling and predicting the optical characteristics of the …

Differential Cross Sections for Compton Scattering Off the Proton at 185 MEV
A complete angular distribution of Compton scattering off the proton was measured at average laboratory bremsstrahlung energy of 185 MeV. The experiment was per-formed at the Saskatchewan Accelerator Laboratory using the new high duty factor elec-tron beam. The scattered photons were observed with …

Strongly coupled plasmas and the QCD critical point
… non-Gaussian, moments of the event-by-event distributions of pion, proton and net proton multiplicities, as well as estimates of various measures of pion-proton correlations. We show how to use parameter independent ratios among these fluctuation observables to discover the critical point, if …
