Abstract :
The beam size at the low emittance configuration of the Photon Factory was measured by the use of the SR interferometer. The spatial coherence of the visible SR beam was measured for both of the vertical and horizontal directions with the wavelengths at 500 nm and 633 nm. From the measured spatial coherence of the SR beam, the beam size measurements of 87.3 μm in the vertical and 261.2 μm in the horizontal were obtained. The observed horizontal beam size agreed with the designed beam size
