The error of the g-factor was estimated and the measurement efficiency was compared at two locations of the LHC accelerator: at the LHCb detector (IR8) and at the LHC pulse purification region (IR3). A special orientation of the crystal was found, which makes it possible to measure the dimensionless electric dipole moment ΛC with almost the same accuracy as its g-factor. The estimated error of the g-factor after 10 years of data collection using the installation of a 40 mm tungsten target and a germanium crystal on LHCb and IR3 is Δg = 0.100 and Δg = 0.037, respectively. Based on the study of interference effects in radiation spectra from ultrarelativistic electrons in different targets (amorphous target of finite thickness, two thin amorphous targets, field in finite magnet, double scattering at certain angles), generalization and regional nature of contributions.  Product Description popup.authors Bondarenco Mykola V.
