Abstract: The innovation of the X－ray detector X′Celerator has brought a revolution to X－ray powder diffra- ction by enhancing the data acquisition speed more than 100 times. The pre－fixed and factory－aligned optical modules make it possible for the first time to exchange the optical configurations for various applications in a few minutes without optical re－alignment, which was a dream for years. The different kinds of new optical modules/developments have increased the X－ray diffractometer usage efficiency significantly, resulting in better quality data with shorter scan time. The new intelligent software makes the analytical results more reliable and accurate and much more easily.
