| 英文摘要 | Support-mesh structures of a self-supporting transmission grating may decrease the transmission area and diffraction efficiency, thus exert a ill effect on the original diffraction pattern of the grating and make it complicated to apply, especially in soft X-ray region. To solve this problem, we put forward a method to realize a kind of totally self-supporting transmission grating by arranging the rectangular transmission holes in a high Z foil quasi-randomly. Based on Fraunhofer's diffraction theory, we make a theoretical analysis on the diffraction pattern of this new kind of grating. We also calculate the diffraction pattern of this new kind of grating based on the Kirchhoff's diffraction theory. Further more, we fabricate a sample grating of 1000 lines/mm using a focused ion beam (FIB) technology and then test it with the beam line 4B7B on the Beijing synchrotron radiation facility. Theoretical analysis and experimental result both show that the diffraction of the transmission grating can remove the ill effect of the support-mesh structures by using this newly designed method. Such a method can profit us in applications of this kind of X-ray dispersive element to a wide extent. |
