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
