Abstract
A possibility of a few MeV electron beam diagnostics (Lorentz-factor ∼ 10) using polarization characteristics of the optical transition radiation (OTR) have been considered. Determination of the electron beam divergence have been performed with technique based on the OTR measurements. The technique is based on measuring the ratio R=Imin/Imax, where Imin(Imax) is the photon yield in the minimum (maximum) of OTR angular distribution. It is shown that the value of R can be obtained also from the measurement of the so-called ψ-scan of the OTR yield registered by a fixed detector with the aperture ≤γ-1 by varying the target tilt angle with respect to the electron-beam. The experiment carried out at 6.1 MeV Tomsk microtron has demonstrated the feasibility of the technique proposed.
