| Abstract: | The paper analyses the ideal relative transmission efficiency of sagittal focusing double crystal monochromator,and the cause of the deformation of the first crystal and of the effect on the transmission efficiency of the second crystal respectively by high heat flux and anticlactic deform,tells the restrain of the deformation and influence from theory and structure and the result of those by SHADOW,and gets the factual transmission efficiency. |
