TI - Beam Size Measurements using Synchrotron Radiation Interferometry at ALBA J2 - Proc. of IBIC2014 AB - First tests to measure the transverse beam size using interferometry at ALBA showed that the measurement reliability was limited by the inhomogeneous light wavefront arriving at the double slit system. For this reason, the optical components guiding the synchrotron radiation have been exchanged, and detailed quality checks have been carried out using techniques like the Fizeau interferometry or Hartmann mask tests. We report the results of the analysis of the optical elements installed in the beamline, and the beam size measurements performed using double slit interferometry in both horizontal and vertical planes.
