Experience high speed, high flux, and high confidence. The DECTRIS JUNGFRAU® represents DECTRIS's inaugural charge-integrating detector, designed to withstand the intense flux levels generated by fourth-generation synchrotrons.
Its per-pixel charge-integration feature, equipped with three-tier dynamic gain switching, efficiently captures individual photons and the strongest Bragg peaks in a single frame, avoiding saturation, at an uninterrupted rate of 2000 frames per second across the entire four-megapixel active region.
Each 75 µm pixel chooses one of three calibrated gain levels based on the amount of charge it gathers, providing sensitivity to single photons at low light levels and over 10,000 photons per pixel in each frame at the highest end.
Charge integration does not impose an immediate limit on the count rate, and the consistent 2000 Hz readout effectively captures every frame of the experiment for seconds, minutes, or even hours. Autosummation on the detector merges sub-frames in real time, which enhances the effective dynamic range and provides completely calibrated images at the required frame rate.
This detector is designed specifically for uses that require the highest local intensities, including serial synchrotron crystallography (SSX); high-flux MX operating at kilohertz frame rates; pump-probe experiments; and time-resolved SAXS/WAXS. It offers full-frame speed, an uncompromised dynamic range, and the reliability associated with DECTRIS.
- Full-speed, full-frame: Continuous recording at 2000 fps across the entire 4 MP frame, applicable to each measurement frame, rather than being limited to a specific burst
- Enhanced dynamic range for highest flux: Ranging from single photons to more than 10,000 photons per pixel per frame without any immediate count-rate restrictions: an effective addition to photon counting
- Photon counts, readily available: Energy calibration, pedestal adjustment, flat-field correction, and automatic summation transform the raw signals into photon counts for users, eliminating the need for any offline processing
- Simple to incorporate and dependable: JUNGFRAU employs the identical SIMPLON API, HDF5/NeXus, and Streaming interfaces as EIGER2 and PILATUS4, provided and supported according to DECTRIS standards
Testimonial
The DECTRIS JUNGFRAU is fully suitable for any application in crystallography, out of the box. We collected precise and accurate rotation MX data.
