For a demonstration of the performance of the X-ray interferometer, we propose a test at the long-range Imaging and Medical Beamline (IMBL) at the Australian Synchrotron. The Australian Synchrotron is a SR facility in the Australia, and it has a remarkable long range beamline for medical imaging. We can construct a Young’s type double slit interferometer in this beam line which will be similar to the design proposed for the FCC-ee SR monitor. A visible light SR interferometer on the neighbouring Optical Diagnostic Beamline (ODB) will be used as the gold standard for cross checking the performance of the novel x-ray interferometer. These measurements will be tested in the vertical plane due to the exceptionally small vertical beam size that can be achieved in the Australian Synchrotron storage ring.
