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.
