[PDF][PDF] Submillisecond X-ray photon correlation spectroscopy from a pixel array detector with fast dual gating and no readout dead-time
Journal of synchrotron radiation, 2016•journals.iucr.org
Small-angle scattering X-ray photon correlation spectroscopy (XPCS) studies were
performed using a novel photon-counting pixel array detector with dual counters for each
pixel. Each counter can be read out independently from the other to ensure there is no
readout dead-time between the neighboring frames. A maximum frame rate of 11.8 kHz was
achieved. Results on test samples show good agreement with simple diffusion. The potential
of extending the time resolution of XPCS beyond the limit set by the detector frame rate …
