摘要：
An x-ray beam line BL-3A at the Photon Factory has been designed and constructed to have optical components of a collimating paraboloidal mirror, a sagittal-focusing double-crystal monochromator, and a focusing paraboloidal mirror. The evaluation at the (+, -, -) setting of Si (111) showed that the vertical angular divergence was reduced from 13.4 to 9.5 (arcsec) by the collimating mirror. The vertical focusing with two mirrors gave the beam size of 0.2 mm (1/50). The horizontal beam size was reduced to 1/60 by sagittal focusing.
