【 摘 要 】
A polarizer of V-cavity type for small angle diffractometer was considered. The device performance was simulated using McStas ray tracing package with the input parameters for supermirrors of PNPI home production (CoFe/TiZr, m = 2.13). Two replaceable devices with lengths 0.75 m and 1.8 m are proposed to cover the wavelength range 4-25 Å with beam polarization not less than 95%.
