The quick scan and step scan are realized by a torque motor directly driven Bragg axis, controlled by a servo controller. This design allows easy and remote control of the oscillation frequency and angular range, providing comprehensive control of QXAFS measure-ments. The cryogenically cooled Si (311) and Si(111) crystals, which extends the energy range from 4.8 keV-45 keV. The dynamic analysis verifies the rationality of the mechanical structure design. The device was fabri-cated and tested, results show an oscillation frequency up to 50Hz with a range of 0.8°, and a resolution of 0.2 arcsecond in step scan mode. This device demonstrates the feasibility of large range quick scan and step scan by a single servo control system.
