摘要4B9A is a focusing and monochromatic photon beam at the BSRF, which was constructed in 1990. During the second phase of the BSRF program, the surface of the cylindrical mirror has been coated with Pt, covering the original Ni, and the monochromator has been upgraded. The maximum photon energy extends to 11 keV and the intensity has increased about tenfold with respect to the previous intensity at 6 keV. Synchrotron X-ray diffraction patterns for the Hg-1223 (HgBa2Ca2Cu3O8+delta) superconducting bulk and thin film have been measured at 1.54014 Angstrom. Results indicate that the bulk and film can be indexed as possessing tetragonal symmetry; lattice parameters a = 3.856 Angstrom and c = 15.851 Angstrom for the bulk Hg-1223 compound, and a = 3.8517 Angstrom and c = 15.8511 Angstrom for the film. Their structures are similar.
