The newly formed Medipix Collaboration, including the European Organization for Nuclear Research (CERN) of Geneva, Switzerland, and PANalytical of Almelo, Netherlands, as well as other research institutes including Nikhef of Amsterdam, the national institute for subatomic physics in the Netherlands, have developed the Medipix2 chip, a photon counting x-ray detector.

The collaboration said its Medipix2 consists of a 300 μm silicon detector layer, which is attached to a pixel read-out chip with 256x256 55 μm square pixels. Medipix2 has applications ranging from materials analysis to medical imaging.

Klaus Bethke, senior system architect at PANalytical, said: “PANalytical’s role in the Medipix2 Collaboration has been to transfer the technology from CERN and develop it into a product.”

The original aim of the Medipix2 collaboration was to develop the system for medical imaging, such as mammography and heart investigations, the companies said.

PANalytical’s PIXcel is designed for advanced x-ray diffraction applications, which delivers new levels of resolution and linearity and an unmatched dynamic range of 13 million counts per second per pixel row, the collaboration said.
