Researchers engaged on the Antihydrogen Experiment: Gravity, Interferometry, Spectroscopy (AEgIS) mission on the European Group for Nuclear Analysis (CERN) have discovered a surprisingly low-cost gadget that may ship “unprecedented” decision for antimatter pictures: the standard smartphone digital camera sensor.
“For AEgIS to work, we want a detector with extremely excessive spatial decision, and cell digital camera sensors have pixels smaller than one micrometer,” explains principal investigator Francesco Guatieri. “We’ve got built-in 60 of them within the single photographic detector, the Optical Photon and Antimatter Imager (OPHANIM), with the very best variety of pixels presently operational: 3,840 [megapixels]. Beforehand, photographic plates have been the one possibility, however they lacked real-time capabilities. Our answer, demonstrated for antiprotons and instantly relevant to antihydrogen, combines photographic-plate-level decision, real-time diagnostics, self-calibration, and a great particle assortment floor, multi functional gadget.”

That smartphone picture sensors enhance each era isn’t any secret: in solely a few a long time telephone cameras have gone from blurry, sub-VGA decision snapshots to multi-megapixel pictures able to going toe-to-toe with devoted digital camera {hardware} — however utilizing them to take snapshots of antimatter is one thing their producers have most likely not thought-about. Combining 60 business sensors on a custom-built antimatter digital camera the crew confirmed that it is attainable to seize low-energy positrons in real-time at a decision excessive sufficient to be helpful within the AEgIS experiment, during which a beam of antihydrogen is produced and its vertical displacement measured utilizing a moiré deflectometer.
If you happen to’re fascinated about taking your individual antimatter pictures, although, it isn’t fairly as simple as pointing your smartphone at an antihydrogen supply — assuming you’ve entry to at least one within the first place. With a view to adapt the sensors, they required cautious {hardware} modification. “We needed to strip away the primary layers of the sensors, that are made to cope with the superior built-in electronics of cellphones,” Guatieri explains. “This required high-level digital design and micro-engineering.”

“This can be a game-changing know-how for the remark of the tiny shifts because of gravity in an antihydrogen beam touring horizontally, and it might probably additionally discover broader functions in experiments the place excessive place decision is essential, or to develop high-resolution trackers,” claims AEgIS spokesperson Ruggero Caravita of the crew’s creation. “This extraordinary decision permits us additionally to tell apart between totally different annihilation fragments, paving the best way for brand new analysis on low-energy antiparticle annihilation in supplies.”
The crew’s work has been revealed within the journal Science Advances below open-access phrases.
