TOMSK, Jun 25 – RIA Tomsk. An employee of Tomsk State University (TSU) won a grant to develop a new data storage algorithm for the Large Hadron Collider (LHC), as well as an internship at the European Organization for Nuclear Research (CERN), the university’s press service said on Thursday.

"Yuri Bordulev, an employee of the Laboratory for high-energy physics data analyzing of the Faculty of Physics received a grant from the ATLAS international collaboration to develop new data storage algorithms. Using these algorithms, it is necessary to reduce the amount of data stored while preserving information. The grant will allow a TSU physicist to undergo a six-month internship at CERN", – is said in the message.

It is explained that ATLAS – is one of the particle detectors of the Large Hadron Collider. This is one of the largest scientific facilities in the world, consisting of many interconnected systems and services. During operation ATLAS generates an unprecedentedly large flow of data - tens of petabytes per year. These data should be stored for subsequent analysis by physicists.

"The problem is that CERN data warehouses are already operating at the limit, and with the start of a new experiment in 2021, the existing capacities will not be enough. In this connection, the task was set: to reduce the amount of stored data while saving information", - Bordulev is quoted in the message.

To do this, it is necessary to develop a new algorithm for storing data, apply it to all the data that was collected for 2018, implement this algorithm in the ATLAS system and "befriend" it with all the services that access the storage, the press service adds with a link to the researcher .

It is noted that one of the results of the project should be the appearance in Tomsk team responsible for the development of ATLAS data storage system.

Earlier it was reported that TSU scientists, thanks to the detectors they developed, entered the ATLAS experiment group, which is engaged in the search for superheavy elementary particles, such as the Higgs boson, at CERN. Conseil Européen pour la Recherche Nucléaire - is Europe's largest international scientific organization in the field of nuclear physics. Located in Switzerland. Operates the Large Hadron Collider.
