Microfluidic capillary flow set-up. (a) The portable set-up consists of a syringe pump (bottom left), water-cooled sample mount on a motorized stage (center) and photodiode (behind the sample mount). The sample mount is assembled close to the ultrahigh-vacuum beampipe which is capped with a beryllium window. (b) Front view of the temperature-controlled sample mount. The horizontal slits hold the capillary horizontal to the beam. The photodiode allows detection of attenuated beam through the aluminium sample mount, and the alignment of the capillary tube is carried out by horizontal and vertical slits. |
