Detectors are spread across a plain in western Argentina, covering an area roughly 30 times the size of Paris. Built on this scale, the site measures some of the highest-energy particles that reach Earth.<\/p>\n
These particles arrive from space with energies that exceed anything man has yet achieved<\/strong> using particle accelerators. Researchers still do not know what causes the highest-energy cosmic rays or how they reach such extreme energies.<\/p>\n More than 1,600 detector stations at the Pierre Auger Observatory track these rare events.<\/p>\n Cosmic-ray air showers passing through the area are recorded by the network<\/strong>.<\/p>\n How do these water tanks really work?<\/p>\n Cosmic rays arrive at all times, but only rarely does one with an extremely high energy level (greater than 10^19 eV) arrive. Finding out more about the properties of these rare particles is difficult due to their scarcity. According to the project information, there is approximately 1 particle with energy > 10^19 EV<\/strong> that enters every km2 every year.<\/p>\n Because these events are so exceptionally rare, scientists need a large area to collect enough data.<\/p>\n The Pierre Auger Observatory was developed in an effort to obtain as much data as possible<\/strong> regarding these rare events.<\/p>\n When an ultra-high-energy cosmic ray strikes Earth’s atmosphere, it produces a shower of secondary particles. The particles spread outward as they move toward the ground and can cover a large area.<\/p>\n Researchers track both the size of an air shower and how<\/strong> it develops as it moves through the atmosphere. Small differences in timing, location, and intensity can reveal details about the original cosmic ray.<\/p>\n According to the Pierre Auger Observatory<\/a>, these events can spread across a vast area and require multiple detection methods.<\/p>\n Because these events often occur over thousands of square kilometers, researchers need a way to collect data<\/strong> across a vast area.<\/p>\n They also need information from both near the ground and high above the observatory.<\/p>\n Scientists at Instytut Fizyki J\u0105drowej PAN<\/a> are helping study these ultra-high-energy cosmic rays and the air showers they produce.<\/p>\n Researchers at the Pierre Auger Observatory solved this problem of detecting these rare events by developing a dual-component system. One component consists of a massive collection of water-based surface detectors covering the plains of Argentina.<\/span><\/p>\n Each detector container holds approximately 12 tons of ultra-pure water and serves as a particle detector. When charged particles from an air shower enter a detector tank, they move through the water faster than light<\/strong> can travel in water.<\/p>\n This produces Cherenkov light, which appears as brief flashes inside the detector tank. Each detector tank contains three photomultiplier tubes that detect these flashes and convert them into electrical signals.<\/span><\/p>\n GPS timing allows researchers to compare signals<\/strong> from multiple detectors at nearly the same moment.<\/p>\n The amount of light recorded by the detectors provides clues about the energy of the incoming cosmic ray<\/a>.<\/p>\n Comparing signal timing from different detectors helps determine the path of the incoming cosmic ray<\/strong>.<\/p>\n Researchers also use fluorescence telescopes to observe ultraviolet light produced by air showers<\/a> higher in the atmosphere. Together, the two systems provide independent observations of the same air shower.<\/p>\n This provides a clearer picture of these rare events. Over the flat expanse of Argentina’s plains, water-based detector units continue recording data around the clock<\/strong>.<\/p>\n Some of nature’s most energetic events pass through the observatory each year and leave behind valuable data.<\/p>\n Measurements from the observatory are being used to investigate the origin of mysterious ultra-high-energy cosmic rays<\/strong>.<\/p>\n Another goal is to understand how these particles acquire such extraordinarily high energies<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" Detectors are spread across a plain in western Argentina, covering an area roughly 30 times the size of Paris.
