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.

20th Anniversary Symposium on Medipix and Timepix

The Medipix2 Collaboration will celebrate 20 years of activity in 2019. To mark the occasion, a special symposium on Medipix and Timepix will be held at CERN on 18 September. The symposium will be an occasion to show the ASIC developments at the heart of the work of the Collaborations as well as some of the numerous applications to which Medipix and Timepix have been applied. The symposium will be open to all past and present members of the Medipix Collaborations as well as various academic, educational and commercial partners. Members of the wider CERN community are also warmly welcome to...Read more
