New Delhi: The Large Hadron Collider has completed a highly successful run of colliding protons using a pair of beams circulating in opposite directions. By boosting particles to high energies, making them collide, and then carefully examining the resulting shower of short-lived particles, scientists can test and validate existing theories of physics, and potentially uncover unknown physics beyond human knowledge. The performance of the Large Hadron Collider allowed scientists to gather much more data on particle interactions than all the previous proton collision runs conducted so far, thanks to significant upgrades to the world’s most powerful particle accelerator.
There are a number of experiments or particle detectors positioned around the Large Hadron Collider, each of which are investigated by thousands of scientists from hundreds of academic institutions around the world. Most of the sub-detectors in the LHCb experiment was replaced or upgraded with the demanding data-gathering operations. The upgrades allowed the particle physicists to gather more data and conduct more precise measurements. Apart from interactions between protons, the run has also allowed scientists to probe the collisions between protons and a variety of gases, potentially providing more valuable insights on particle interactions to scientists.
A constantly upgraded instrument
The Large Hadron Collider is being constantly upgraded between observation runs, allowing for capturing information on particle interactions at increasingly higher energy levels. Along with the hardware for the acceleration and the detection, the data acquisition and trigger systems have also been upgraded, with the events being assembled at a bandwidth of 40 Tb per second. Graphic Processing Units provide the first layer of event selection, followed by more sophisticated algorithms that are using an upgraded computer farm, providing scientists with real-time analysis of collisions. Nearly 40 petabytes of data were collected during the run, that has been distributed to over 20 computing centres across the world for further analysis.
