Hard X‐ray phase‐contrast imaging with the Compact Light Source based on inverse Compton X‐rays

The first imaging results obtained from a small‐size synchrotron are reported. The newly developed Compact Light Source produces inverse Compton X‐rays at the intersection point of the counter propagating laser and electron beam. The small size of the intersection point gives a highly coherent cone beam with a few milliradian angular divergence and a few percent energy spread. These specifications make the Compact Light Source ideal for a recently developed grating‐based differential phase‐contrast imaging method.
