Project Description: 

Medipix3 is a CMOS pixel detector readout chip designed to be connected to a segmented semiconductor sensor. Like its predecessor, Medipix2, it acts as a camera taking images based on the number of particles which hit the pixels when the electronic shutter is open. However, Medipix3 goes much further than Medipix2 permitting colour imaging and dead time free operation. A novel charge summing and allocation scheme is implemented at the pixel level permitting proper binning of the energy of incoming photons overcoming the effects of fluorescence and charge diffusion. As there are 2 counters in each 55μm pixel the chip can be programmed such that one counter is being read out while the other is counting. It is also possible to connect the chip to a sensor matrix with a pitch of 110μm. In this way, up to 8 counters are available per pixel.

Some projects using this technology: 
  • Medipix X-ray Technology: from Particle Tracking to Aviation Inspection
    ADVACAM – a company using CERN Medipix technology - developed a new range of X-ray imaging cameras optimised for composite material testing.
  • X-Ray Eyes For Art Authentication And Restoration
    The Medipix collaboration technology is finding its way into the cultural heritage field, where its used for art restoration and imaging.
  • The Medipix Chips and Collaborations: from medical imaging to space dosimetry.
    Originally developed for use in the Large Hadron Collider (LHC) experiments, the Medipix technologies have made the journey from CERN to applications across a wide range of sectors - an outstanding example of how technology developed at CERN can create societal impact.
