Some history

The ESRF has operated a high resolution powder diffraction beam line with users since 17 May 1996. The original beamline, BM16, was built on a bending magnet, and was transferred in 2002 to an undulator source to exploit the greatly increased flux and collimation available. Thus on 12 March 2002 BM16 measured its last powder diffraction pattern and the diffractometer was transferred to the newly constructed ID31, which performed its first user experiment on 26 June 2002 [1].

After 11.5 years powder diffraction was relocated at ID22, to liberate ID31 for the construction of an ESRF Upgrade nanofocus beamline. Five months after ID31 closed on 18 December 2013, the first user samples were run on ID22 in May 2014. The transfer from a low-β sector of the ring to a high-β sector, coupled with the provision of in-vacuum and revolver undulators, increased the X-ray intensity by more than a factor of two. Further developements are forseen for the course of 2015, including the installations of a transfocator, a new diffractometer and a 2D detector.
