Book excerpt: Using the Berkeley polarized-proton target, we have measured the polarization parameter P([theta]) for proton-proton (p-p) scattering. The measurements were obtained at beam kinetic energies of 0.330, 0.680, and 0.740 GeV at the 184-in. synchrocyclotron and 1.70, 2.85, 3.50, 4.00, 5.05, and 6.15 GeV at the Bevatron. The angular regions measured were from 20 to 100 degrees center of mass; the square of the four-momentum transfer ranged from 0.1 to 0.8 (GeV/c)2.

Book Measurements of Polarization Transfers in Real Compton Scattering by a Proton Target at JLAB  A New Source of Information on the 3D Shape of the Nucleon

Download or read book Measurements of Polarization Transfers in Real Compton Scattering by a Proton Target at JLAB A New Source of Information on the 3D Shape of the Nucleon written by and published by . This book was released on 2015 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis work, results of the analysis of the polarization transfers measured in real Compton scattering (RCS) by the Collaboration E07-002 at the Je fferson Lab Hall-C are presented. The data were collected at large scattering angle (theta_cm = 70deg) and with a polarized incident photon beam at an average energy of 3.8 GeV. Such a kind of experiments allows one to understand more deeply the reaction mechanism, that involves a real photon, by extracting both Compton form factors and Generalized Parton Distributions (GPDs) (also relevant for possibly shedding light on the total angular momentum of the nucleon). The obtained results for the longitudinal and transverse polarization transfers K_LL and K_LT, are of crucial importance, since they confirm unambiguously the disagreement between experimental data and pQCD prediction, as it was found in E99-114 experiment, and favor the Handbag mechanism. The E99-114 and E07-002 results can contribute to attract new interest on the great yield of the Compton scattering by a nucleon target, as demonstrated by the recent approval of an experimental proposal submitted to the Jefferson Lab PAC 42 for a Wide-angle Compton Scattering experiment, at 8 and 10 GeV Photon Energies. The new experiments approved to run with the updated 12 GeV electron beam at JLab, are characterized by much higher luminosities, and a new GEM tracker is under development to tackle the challenging backgrounds. Within this context, we present a new multistep tracking algorithm, based on (i) a Neural Network (NN) designed for a fast and efficient association of the hits measured by the GEM detector which allows the track identification, and (ii) the application of both a Kalman filter and Rauch-Tung-Striebel smoother to further improve the track reconstruction. The full procedure, id est NN and filtering, appears very promising, with high performances in terms of both association effciency and reconstruction accuracy, and these preliminary results will be discussed in detail in the last chapters.

Book A Measurement of Proton proton Polarization and Triple Scattering Parameters D  R  A  and A  at 430MeV

Download or read book A Measurement of Proton proton Polarization and Triple Scattering Parameters D R A and A at 430MeV written by Richard F. Roth and published by . This book was released on 1964 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The polarization parameters P, D, R, A, and A' were measured at 7 scattering angles between 30 degrees and 120 degrees in the center of mass with an incident energy of 430 MeV. A 56% polarized beam was prepared by scattering on an internal beryllium target in the Chicago Synchrocyclotron. A liquid hydrogen target was used for the p-p scattering and the outgoing polarization was analyzed with a third scattering in the carbon plates of a spark chamber. The scattering asymmetry was determined by fitting the data to a distribution by the maximum-likelihood method. The analysing power of the spark chamber as a function of energy was measured in beams of known polarization. The beam polarization before and after the p-p scattering was manipulated with a solenoid and two bending magnets. During a 5-weeks run, 1,400,000 pictures were taken. The pictures were scanned and measured on angular encoding machines with a least count of 1/3 degree. The measurements are compared with the extrapolations of several phase shift and resonance analyses of experimental data at higher and lower energies. (Author).

Book Analyzing Power Measurements in High P

Download or read book Analyzing Power Measurements in High P written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The analyzing power in 28 GeV/c proton-proton elastic scattering was measured at P/sub perpendicular to/2 = 5.95 and 6.56 (GEV/c)2 y/sub g/ a polarized proton target and an unpolarized proton beam at the Brookhaven National Laboratory AGS. Results indicate that the analyzing power, A, is rising sharply with P/sub perpendicular to/2. Previous measurements of the analyzing power, A, in p + p .-->. p + p suggested a rise in A at large-P/sub perpendicular to/2, but the statistical uncertainty in the highest point at P/sub perpendicular to/2 = 5.95 (GeV/c)2 made it impossible to determine the magnitude of the increase. In an effort to clarify this situation, we made new measurements of A at P/sub perpendicular to/2 = 5.95 and 6.56 (GeV/c)2. An unpolarized beam of typically 5 x 101° 28 GeV/c protons from the AGS at Brookhaven National Laboratory was incident upon the University of Michigan polarized proton target. This target contains irradiated ammonia beads cooled to 0.5°K by a 3He-4He evaporation refrigerator, in a 2.5 T magnetic field. The polarizing transitions are driven by a 70 GHz microwave system. The polarization of the hydrogen protons is measured with a 107 MHz NMR system, and is typically P/sub T/ = 45% with beam and 60% without beam.
