Multilayer La/B_4C mirrors in the spectral region near 6.7 nm

摘要

The results from measuring reflection factors are presented for multilayer La/B_4/C mirrors with barrier layers of carbon and scandium. It is shown that a higher reflection factor is obtained by depositing a layer of carbon onto a surface of boron carbide. This effect is caused by diminishing absorption in the structure and the reduced width of transition regions.
