Key Points

The study aims to enhance efficiency in analyzing large-scale datasets from X-ray photon correlation spectroscopy using a new multi-tau two-time correlation method.
Developed a multi-tau two-time correlation (MT-2TC) analysis technique.
Implemented the algorithm in dense and sparse data formats.
Conducted experiments on bulk GeO2 glass and v-Ta2O5 thin film at the ESRF ID10 beamline.
MT-2TC method achieved nearly two decades of temporal correlation range.
Demonstrated perfect agreement with standard correlation analyses.
Improved signal-to-noise ratios at long lag times.
