As of 2023, the SX-165 CCD detector is out of production. Please ask us if you are interested in a used but refurbished and tested instrument.
SX-165 CCD Detector
The SX Series are the only CCD X-ray detectors that are ideal for both synchrotrons and rotating anode X-ray sources. The SX-165 features a round, 165 mm diameter active area, and a versatile, high-resolution CCD chip. The SX-165 is the upgraded version of the very successful marCCD X-ray detector. From macromolecular crystallography to small angle X-ray scattering (SAXS), the SX-165 is known throughout the world for unsurpassed imaging and excellent reliability. The SX-165 retains the same design and construction as the marCCD, but features a modernized and improved controller, and higher gain. It also has a frameshift mode of readout for time-resolved imaging on the order of milliseconds. The SX-165 can be used with or without the mardtb goniostat.
Highlights
SINGLE CHIP, LARGE DETECTING SURFACE
LOW NOISE, FAST READOUT
LOW TEMPERATURE, LOW DARK CURRENT
FACTORY CALIBRATION
TIME-RESOLVED IMAGING IN MILLISECONDS
- On-chip hardware binning - software selectable
- Phosphor: Gd2O2S:Tb <40 μm thick
- Closed-circle refrigeration at -80°C
- CCD sensors are selected for low noise and low number of cosmetic blemishes. All defects are correctable and permanently mapped and corrected by our factory calibration procedure. Fiber optic tapers are low Thorium glass with extra mural absorption (EMA) selected for minimal geometric and shear distortions
- Proprietary PCI busmaster DMA Controller with kernel level driver
- Direct transfer of data, in real time, to workstation memory with no involvement of workstation CPU
- Optically isolated digital input for external trigger of shutter and/or readout
- Optically isolated digital output as trigger for external shutter controller
- High current driver circuit for external solenoid shutter
(24V open pulse, 3V hold).
