Testing the limits: serial crystallography using unpatterned fixed targets.

ABSTRACT: Sheet-on-sheet (SOS) fixed-target chips are arguably the most versatile, cheapest and simplest sample-delivery method for ambient-temperature data acquisition using serial crystallography approaches at synchrotrons and X-ray free-electron lasers (XFELs). Their defining feature, the absence of any hard-patterned restrictions around crystals, is their strength as it removes limitations on crystal sizes or environments. However, it is also their weakness when it comes to limiting undesired effects on yet-to-be-irradiated crystals due to diffusing heat, radicals or gas originating from previous exposures. We explored whether SOS chips can be used for damage-free serial data collection on the new ID29 beamline at the ESRF-EBS, a fourth-generation synchrotron light source, as well as at the new
