Mott electron polarimetry
Did you know?
NettetPolarimetry of high energy electron beams (on the order of 1 GeV or larger) is typically accomplished using Møller and Compton polarimetry. Møller polarimetry makes use of the scattering of the polarized beam electrons from polar-ized target electrons, the latter usually found in a magnetized ferromagnetic foil. Compton polarimeters make use of Nettetmeasuring electron polarization arise from backgrounds, systematic effects, various “dirt” effects, and possibly statistics. The underlying science that initially drove the need for, and currently drives the required precision of electron polarimetry is parity violation. The reasons for this are fairly straightforward.
NettetElectron polarimeters based on Mott scattering are extensively used in atomic and molecular, solid state, nuclear, and high-energy physics. This use stems from the … Nettet19. sep. 2024 · Electron polarimetry benefits from the ability to use processes with well-known analyzing powers, hence enabling high precision measurements. Several …
NettetIn standard Mott electron polarimetry using thin gold film targets, extrapolation procedures must be used to reduce the experimentally measured asymmetries A to the values they would have for scattering from single atoms. These extrapolations involve the dependent of A on either the gold film thickness or the maximum detected electron … NettetThere are three common techniques for measuring the electron polarimetry. The first one is the Mott polarimeter, electrons are scattered by the Coulomb field of a heavy …
