Figure 3
X-ray beam position monitor (XBPM). (a) 3D model of an XBPM at SLS 2.0. IDFEs featuring: (1) support, (2) motion stage, (3) encoders and (4) vacuum chamber. (b) Detail showing the 0.2 mm-thick tungsten blades behind the water-cooled copper shielding. (c) Photograph of a partially disassembled blade holder. (d) Power-density plot and (e) current-density plot, both indicating the new blade position with solid black lines. The solid yellow lines indicate the blade position without changes (i.e. SLS configuration). The field of view in both plots represents the synchrotron beam at the position of the XBPM, while the small rectangle in the centre corresponds to the beam used by the beamline (i.e. after the diaphragm).
