| Abstract |
Recently our group starts to investigate a feasibility of double diffraction radiation (DR) target interferometry for non-invasive micro-train beam diagnostics at KEK: LUCX facility. Double DR target consists of two metal plates and one of them can be moved relative to another along the beam trajectory. Micro-train beam is a sequence of short electron bunches with sub-ps spacing. As it was shown* double DR target can be used for such a beam diagnostics measuring DR yield versus plates displacement. The obtained tuning curve (interferogram) allows to determine a number of bunches within the micro-train and spacing between them. In order to design a reliable device for this aim we have to take into account different double DR target interferometer plate’s adjustment inaccuracies. These inaccuracies can be as follows: inaccuracies in the mutual adjustment of plates tilt angles to the beam trajectory, outer plate edge shift along the beam trajectory and other. The influence of the bunch form-factor shape is also considered. We investigated double DR target preparation accuracy requirements in order to minimize measurements uncertainties and increase interferometer resolution.
