The research team at AEgIS CERN has reported on the detection of antimatter-matter collisions. In this case, the collision of antiprotons annihilations. Initially developed with the specialized Timepix3 sensor, which was costly and produced subpar image quality, they switched to using mobile phone camera sensors. They found that the image quality improved significantly and the cost decreased by a thousandfold.
The sensor used in this project is the popular Sony IMX219, commonly used as a camera for Raspberry Pi. It is wide-reaching, with a complete module costing less than a thousand baht. They assembled 60 units to create collision detection modules, but the sensor had to be modified. The team scraped off the lens and color filter layers for better accuracy.
This new sensor allows for the detection of antimatter-matter collisions with an accuracy of 0.6 micrometers, 35 times more accurate than before. It also solves the issue of slow detection with photographic plates or films that cannot capture in real-time.
