(a) Total experimental time expected for an XPCS experiment as a function of Q. The solid lines represent the required measurement time to achieve a SNR = 10 for PETRA III and PETRA IV. The expected characteristic time τc is shown for two different particle radii. The temporal range from 192 ns to 67.5 µs is accessed via SP mode. The horizontal dash–dotted line at 1.92 µs indicates expected achievable characteristic times. The range above 67.5 µs is covered by the MP mode. The SNR of our experiment is shown in the inset. (b) A histogram of the averaged total photons per single frame with a single Gaussian fit (red dashed line).
