Study of interface reaction in a B4C/Cr mirror at elevated temperature using soft X-ray reflectivity

Journal of Synchrotron Radiation, 2022
Boron carbide is a prominent material for high-brilliance synchrotron optics as it remains stable up to very high temperatures. The present study shows a significant change taking place at 550°C in the buried interface region formed between the Cr ...
