Summary of experimental studies at CERN on a positron source using crystal effects
X. Artru, V. Baier, K. Beloborodov +25
New kind of positron sources for future linear colliders, where the converter is a tungsten crystal oriented on the <111> axis, has been studied at CERN in the WA103 experiment. In…
Impact parameter profile of synchrotron radiation
X. Artru
The horizontal impact parameter profile of synchrotron radiation, for fixed vertical angle of the photon, is calculated. This profile is observed through an astigmatic optical syst…
Angular distribution of radiation by relativistic electrons in a thin crystal
X. Artru, S. P. Fomin, N. F. Shul'ga
The results of theoretical investigation of angular distributions of radiation from a relativistic electron passing through a thin crystal at a small angle to the crystal axis are…
General Constraints on Spin Observables, Applications to Antiproton Proton to Antilambda Lambda and to Polarized Quark Distributions
Xavier ARTRU, Jean-Marc RICHARD
We review the density matrix formalism and the positivity conditions for general multiple spin asymmetries, taking as an example the case antiproton + proton -> antiLambda + Lambda…
Bunch coherence in parametric X-ray radiation
Xavier Artru, Karo A. Ispirian
The amplitude of Parametric X-ray radiation emitted coherently by a bunch of electrons crossing a crystal (CPXR) is calculated. When the bunch density is modulated with a longitudi…
Dynamics of a magnetic monopole in matter, Maxwell equations in dyonic matter and detection of electric dipole moments
Xavier Artru, David Fayolle
For a monopole, the analogue of the Lorentz equation in matter is shown to be f = g (H - v cross D). Dual-symmetric Maxwell equations, for matter containing hidden magnetic charges…
