Abstract

I13L is a 250 m long hard X-ray beamline (6–30 keV) currently under construction at the Diamond Light Source. The beamline comprises two independent experimental endstations: one for imaging in direct space using X-ray microscopy and one for imaging in reciprocal space using coherent diffraction-based imaging techniques. This paper will discuss the coherence branch, where well-defined coherence properties and preservation of the coherent flux are important. We will demonstrate the impact of optical components and stability onto the beamline performance, using phase-space-based ray-tracing techniques. The implications onto the beamline design will be demonstrated using our in-house build quadruple crystal monochromator as an example.
