  1. The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take - off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. the neutron flux at different wavelength, under different reflection and take - off angle of the monochromator and divergency of the first collimator, were given. the simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected

    用蒙特卡羅模擬方法對中子應力衍射譜的設計方案進行了優化研究,提出了一系列可供參考的數據:確定了單色的位置、尺寸、垂直聚焦單色在不同起飛角下的聚焦率半徑和傾角;討論了第二準直的尺寸和發散,以及使用第二準直造成的強損失;給出了在不同單色反射面、起飛角、中子波和第一準直發散的情況下樣品處的中子注量率,以及多種組合情況下譜的解析;對限束方孔的尺寸、距離樣品遠近對強損失和測量中的影響做了深入研究。
