GaliPIX³ᴰ

Extending the range of 2D solid-state pixel detectors

With pixel dimensions of 60 microns x 60 microns and overall sensor dimensions of 30.06 x 24.16 mm, GaliPIX^3D is the newest and largest 2D hybrid pixel detector for XRD. The high-quality CdTe sensor provides unrivalled stopping power for X-rays and affords close to 100% efficiency even for the highest energy radiation, like Ag and Mo. As with the PIXcel^3D this detector is designed to provide state-of-the-art 2D images, data quality and flexibility. The design of the 2D photon counting detector array allows users to switch seamlessly between 1D and 2D modes and to collect frames suitable for 3D processing in computed tomography.
