    Polarimetry

    The recently developed Jefferson Lab Hall-A moller polarimeter Geant4-based simulation [MolPol] is a vital tool in understanding the analyzing power of the polarimeter for parity experiments ranging from PREX-II at 1 GeV to future 11 GeV experiments. I'll discuss the application's role in the development of optics solutions, understanding of e- transportation through the polarimeter and the...

  3. 4. Development of a Dedicated Precision Polarimeter for Charged Particle EDM searches at COSY
    Irakli Keshelashvili (Forschungszentrum Juelich GmbH)

    Polarimetry

    The international JEDI (Jülich Electric Dipole moment Investigation) collaboration is preparing a first-ever direct measurement of the deuteron Electric Dipole Moment (EDM), using the COSY storage ring at Forschungszentrum Jülich (Germany).
    A new polarimeter is required to detect the very slow and minuscule polarization change with time: starting in 2016, we have designed, built and...

  4. 3. Polarized Atomic Hydrogen Target at MESA
    Dr Valery Tyukin (KPH, JGU Mainz, Germany)

    Polarimetry

    One aim for the new electron accelerator MESA is to measure the weak mixing angle in electron proton scattering to a precision of 0.14 %. The beam polarization significantly contributes to this measurement. The Møller polarimeter proposed by V. Luppov and E. Chudakov opens the way to reach a sufficiently accurate determination of polarization. At the moment the polarized atomic hydrogen target...

  5. 69. A Double scattering polarimeter for the P2 experiment at MESA
    Matthias Molitor (Mainz)
    26/09/2019, 11:40
    Polarimetry

    The P2 Experiment at the new Mainz Energy-recovering Superconducting Accelerator (MESA)
    aims at measuring the weak mixing angle sin² θ_W at low Q² with high precision. Therefore
    the polarization of the incident electron beam has to be known with a very high accuracy (< 0.5%).
    Conventional Mott polarimeters are limited by uncertainties in the extrapolation and theoretical
    calculations...

  6. 48. IMPROVEMENTS TO THE LASER POLARIZATION MEASUREMENT INSIDE A FABRY-PEROT CAVITY
    Sachinthani Premathilake (University Of Virginia), Dave Gaskell

    Polarimetry

    The Compton polarimeter at Jefferson Lab's experimental Hall A provides a continuous, non-invasive measurement of electron beam polarization via electron-photon scattering. The electron beam passing through the polarimeter intercepts green laser light stored in a Fabry-Perot cavity. Scattered electrons are detected in an electron detector while back scattered photons are detected in a GSO...

  7. 62. Photon Detector for Compton Polarimetry in the PREX-II Experiment
    Adam Zec (University of Virginia)
    26/09/2019, 14:00
    Polarimetry

    The Jefferson Lab Continuous Electron Beam Accelerator Facility’s experimental Hall A employs a Compton polarimeter to measure incoming beam polarization for parity violating electron scattering experiments. The polarimeter operates by amplifying green laser light in a Fabry-Perot cavity which then compton scatters off the incoming electron beam. The scattered photons are then passed through a...

  9. 31. Status of New Low Energy Polarimetry at the Nuclotron Facility
    Roman Kuzyakin
    Polarimetry

    The design of a new universal low energy polarimeter at Nuclotron is presented. It is installed behind the linear accelerator LU-20. The $^3$He target of this setup allows to measure both the vector polarization of protons and the vector and tensor polarization of deuterons. It is assumed that new design of polarimeter will make it possible to measure vector and tensor polarization of...

  10. 20. The source SPI and low energy polarimetry for the NUCLOTRON facility
    Victor Fimushkin
    Polarimetry

    The report describes the JINR polarized ion source (SPI) operating by means of the atomic beam method. The last results of the SPI testing are presented. Polarized and unpolarized deuteron beams as well as polarized proton beam were produced to accelerate in the NUCLOTRON. The problem of polarimetry of low-energy deuteron and proton beams is discussed.
