Development and application of low temperature X-ray diffraction apparatus in High magnetic field

摘要

A cryocooler-cooled split-pair superconducting magnet using high-temperature Bi_2Sr_2Ca_2Cu_3O_10 current leads wassuccessfully constructed. The magnet generated 5.0T at the center of a vertical clear bore of 68mm and a horizontal gap of 58mm, and was combined with an X-ray diffraction apparatus. The performance test of the high field low temperature X-ray diffraction system was carried out in fields up to 5.0 T and at temperatures ranging from room temperature to 7.5K.
