TI - Limitations and Solutions of Beam Size Measurements via Interferometry at ALBA J2 - Proc. of International Beam Instrumentation Conference (IBIC2015), Melbourne, Australia, 13-17 September 2015 AB - The interferometry beamline at ALBA had several limitations which have been overcome over the past years until currently, beam size measurements are successfully performed using this technique. The main limitation has been related to vibrations in the light wavefront transportation along the beamline. Several counter-measures have been taken to overcome these limitations, related both to the software analysis and the mechanical setup, where the conventional double slit system is substituted by a double pinhole in order to obtain more light and a better interferogram. This report describes the current interferometry setup at ALBA, and show some results.
