IK220 high-speed counter card is used at BL14W1 XAFS station of Shanghai Synchrotron Radiation Facility to establish the QXAFS scan system.This system simplifies the hardware structure.Changes in the monochromator energy can be read directly.The synchronization controls and data acquisition between the monochromator and the ionization chamber is achieved.XAFS spectra are acquired successfully by this QXAFS method.The existing hardware of the experiment station is used to the maximum level after the modification.The free switching between the ordinary XAFS methods and QXAFS methods saves time.
