## Abstract When heavily doped with boron, diamond films can become superconducting with critical temperatures __T__~c~ well above 4 K. Here, we measure the reflectivity of such a film down to 5 cm^โ1^, by using both conventional radiation sources and Coherent Synchrotron Radiation. We thus determi
