Fifteen years ago, structural biology met the first PILATUS detector and paved its way to success. Fast data collection, fine phi-slicing, and vastly improved detection of weak and anomalous signals became possible due to a combination of detector's technical features. Absence of detector background, high spatial resolution, a wide dynamic range, and large active area were all packed into reliable and robust detectors.
Back then, it was a revolution; today, it is an evolution. Increased flux at synchrotron sources has enabled serial crystallography, while high-energy beamlines are utilizing hard X-rays to collect more data with less radiation damage. Thanks to the integration of hybrid-pixel detectors, laboratory diffractometers are pushing the limits of what you can achieve with your in-house instrument and what requires synchrotron beamtime.
EIGER2 are the next step in the evolution of HPC detectors: smaller pixels; a shorter readout; a higher count rate, wider dynamic range, and a high quantum efficiency for a wide range of X-ray energies, including hard X-rays.
- Improve spot separation and reduce background overlap thanks to smaller pixels.
- Perform simultaneous, accurate measurements of very strong and weak intensities thanks to the detectors’ superior dynamic range.
- Obtain faster measurements with: simultaneous read/write, a higher frame rate, larger detectors, and a larger region of interest.
Macromolecular Crystallography at Synchrotrons
- Ultra-fine phi-slicing; in meso and serial crystallography with shutterless data collection, negligible dead-time or a continuous readout.
- Reduce radiation damage by taking high-energy measurements with CdTe-based detectors.
- Detectors for 4th-generation synchrotrons offer a high count rate and stable operation.
