The newly introduced PILATUS3 R CdTe series combines the advantages of noise-free single-photon counting with the benefits of direct detection of hard X-rays in large cadmium telluride (CdTe) sensors.
CdTe provides close to 100% absorption efficiency for hard radiation from Mo, Ag, and In. Combined with noise-free single-photon counting, this brings the direct detection of photons from these sources to a new level of sensitivity and accuracy. The absence of readout noise and dark current is of particular advantage when collecting data with a home source: X-ray sources in the laboratory, particularly for hard X-rays, are much weaker than at the synchrotron, requiring longer exposure times and resulting in weaker signals. Thanks to the absence of dark current and readout noise, all PILATUS3 R CdTe detectors outperform every other technology in the laboratory.
Challenging laboratory applications such as charge density studies and pair distribution function analysis rely on hard radiation and on data with outstanding signal-to-noise ratios. The PILATUS3 R CdTe detectors series offers a unique combination of high-efficiency direct detection with noise-free single-photon counting and is the best match for these requirements in the laboratory.
