| Abstract |
Light's linear and circular polarizations are analyzed simultaneously by vector polarimeters mainly in astrophysics. At higher energies Compton scattering or absorption is applied for linear or circular polarization measurements in satellites and accelerators. Here we propose a Compton scattering only vector polarimeter for monitoring photon beams in a non-invasive way. The setup is adjustable to match the initial photons' energy and can be used for diagnosing electrons' passage through undulators. In perspective the proposed device could also be explored to measure topological charge of the novel vortex photon beams.
