Figure 1
SOS sample presentation devices described in this paper. In both photographs, red-coloured microcrystals are mounted between two sheets of 2.5 µm-thick Etnom foil. The chips shown were machined from aluminium, which yields smooth sealing surfaces and a mechanically robust chip. However, 3D printing from PLA, ABS etc. is also an option. Left: the smaller SOSOS incorporates a standard magnetic-button mount compatible with most MX goniometers. It is shown mounted on the goniometer at the ID23-2 endstation of the ESRF synchrotron, Grenoble, France; the detector is off to the left. Right: the larger SOS chip employs magnetic attraction, not just of the loaded chip into a generic mounting cradle but also of the two frame halves to one another for ease assembly during sample loading. The SOS chip is shown positioned for data collection at the Cristallina-MX endstation of the SwissFEL X-ray Free-Electron Laser at the Paul Scherrer Institut, Villigen, Switzerland (see https://www.psi.ch/en/swissfel/cristallina/crmx-fixed-targets). In this view, the detector is off to the right. The SOS chip is placed into its mounting cradle from the detector side. By fabrication of an appropriate adaptor bracket, like that in the photograph, the generic cradle with its chip is readily attached to a fast-scanning stage. |
