The purpose of this beamtime was to observe difference-frequency generation of optical radiation from two-color x-ray pulses and to explore the possibility to use it as a method for the study of light matter interactions at atomic scale resolution. The experiment followed a detailed theoretical analysis of the effect [1]. We did not measure difference frequency generation during that beamtime due to technical challenges.
