Medipix is a family of read-out chips for particle imaging and detection developed by the Medipix Collaborations. The original concept of Medipix is that it works like a camera, detecting and counting each individual particle hitting the pixels when its electronic shutter is open. This enables high-resolution, high-contrast, noise hit free images – making it unique for imaging applications. 

Hybrid pixel detector technology was initially developed to address the needs of particle tracking at the CERN LHC. The Medipix1 chip, which uses identical front-end circuitry to the Omega3 particle tracking chip, demonstrated the great potential for the technology outside of high-energy physics. To further develop this novel technology and take it into new scientific fields the Medipix2 Collaboration was started in 1999, the Medipix3 collaboration in 2005 and finally the Medipix4 collaboration in 2016.

Timepix3 licence

CERN as an authorized licensor of Medipix3 collaboration and ADVACAM s.r.o. have signed a Timepix3 license agreement. Timepix3 chip (TPX3) is the next generation of X-ray and radiation imaging technology. TPX3 has an array of “clever” pixel electronics capable of processing every detected photon. Contrary to common X-ray imaging detectors, the TPX3 is capable of measuring simultaneously position, energy and time-of-arrival of every detected photon. Rather than collecting data frame-by-frame the device generates a continuous stream of event data. The information about detected photon energy...Read more

The 2017 High Energy Physics Prize awarded to Erik H.M Heijne, Robert Klanner and Gerhard Lutz

The 2017 High Energy Physics Prize was awarded to Erik H.M Heijne, Robert Klanner and Gerhard Lutz for their pioneering contributions to the development of microstrip detectors that revolutionised high-precision tracking and vertexing in high energy physics experiments. Erik initiated hybrid pixel detector developmet at CERN and was a founding member of the first Medipix Collaboration. This is a video of Erik's acceptance speech after receiving the prestigous prize.Read more
