The Smartphone Sensor Revolution: Outperforming Traditional Antimatter Detection
Camera sensors that have actually been developed for smartphones are now getting a glorious task in science: They should ensure the recording of antimacy reactions as part of a new research project.
Particle observation with 3840 megapixels
As part of the Aegis collaboration, a groundbreaking detector was developed at the Technical University of Munich (TUM), which for the first time can make the extermination points of antimatter visible in real time with previously unmatched precision. The device that is in the journal Science Advances It was presented, localized anti-proton destruction with a resolution of only 0.6 micrometers-and is therefore 35 times more precise than previous systems.
The Aegis experiments (anti-hydrogen experiment: Gravity, Interferometry, Spectroscopy) take place at the core research center CERN in Geneva, where researchers examine how anti-hydrogen is under the influence of earth’s education. The aim is to understand the gravitational interaction of antimatter – a previously largely unexplored area of physics.
The new detector consists of 60 modified camera sensors that were originally developed for smartphones. These bring it together to a total resolution of 3840 megapixels – the highest pixel value ever used in a detector. The adaptation of the sensors required complex interventions, such as removing certain electronic layers, in order to make them usable for physical measurements.
Francesco Guatieri, the main author of the associated papers, emphasizes the importance of the high resolution: “Only with such a fine imaging can the tiny distraction of the anti-hydrogen particles be precisely understanded by gravity.” Among other things, the system uses a so-called Moiré deflectometer to measure vertical deviations in the otherwise horizontal anti-hydrogen beam.
Manual evaluation
A special aspect of the research project is the role of human analysis. Over 2500 images were manually evaluated – a task that took up to ten hours per image rate, but proven more precise results than automated procedures. In addition to the exact location of the extermination points, the detector also enables the particles such as pions or protons that arise in antimacy annihilation.
Ruggero Caravita, spokesman for the Aegis collaboration, sees a new era for antimatering research: “This technology opens completely new doors for the examination of particle interactions at low energies.” Although further tests and developments are necessary, the new detector is already considered a potential milestone of experimental physics.
