XRD1: present and future General purpose X-ray beamline with a extended spectrum(4-21 keV) from a wiggler source, shared with the SAXS BL. The BL hosts PX and material science experiments, in collaboration with CNR. Andrea Lausi – 7 ° ILSF Users ’ Meeting – Qazvin 20-21 April 2015
XRD1: present and future • Top-up mode introduced serious thermal load problem affecting the BL monochromator. Three water direct-cooled crystals already substituted in the last three years. This was reflected in a reduced (total) flux and enlarged spot size, causing problems both with users and industry (long exposure time, and beam divergence in particular). A closed loop cryogenic system (liquid nitrogen) from Bruker has been purchased and is expected to be tested by the early 2015. XRD1 is expected to be up and running at full capacity at the beginning of 2015. Andrea Lausi – 7 ° ILSF Users ’ Meeting – Qazvin 20-21 April 2015
