HSE has developed a monitoring system for the LHC experiment

(ORDO NEWS) — Scientists from the Research Laboratory for Big Data Analysis Methods (LAMBDA) of the HSE Faculty of Computer Science have created a monitoring system that is used at the LHCb (Large Hadron Collider beauty experiment) of the Large Hadron Collider.

It allows you to monitor the quality of the collected data, and also helps operators quickly find breakdowns.

As you know, scientists collide elementary particles in a collider and look at the result of these collisions. It is very important to qualitatively track what exactly happened during the collision and determine the particle trajectories. The result is a lot of three-dimensional photos – several thousand shots per second.

In fact, the particles are taken by a detector – a huge camera 30 meters long. The camera consists of different layers, each of which performs its own task. For example, the first layer simply passes the particle through itself, reading the reaction of the medium, the next one fixes its trajectory, and the last layer absorbs the particle.

It is very important that the information collection system works correctly so that scientists can get good data to use in their research.

But since the amount of filmed material is very large, the question arises of how to analyze its quality. Any dead pixel on the matrix can have a critical impact on the data, since, for example, the desired particle can be in its place.

Scientists from LAMBDA have proposed a system with artificial intelligence elements that processes all images and looks for anomalies on them , after which it invites the experiment operator to pay special attention only to those launches that the system considers problematic or worthy of attention.

“The Large Hadron Collider is launched in cycles: the first cycle took place from 2010 to 2012, then from 2014 to 2018, the third cycle will last from 2022 to 2024. Right now, CERN is warming up the facility and testing it ahead of a big launch in the coming weeks.

We have prepared a monitoring system for the LHCb experiment, this system allows you to track the status of the experiment from anywhere in the world , and machine learning algorithms reduce the time required to find problems with the data,” says Denis Derkach, senior researcher at the LAMBDA laboratory.

LHCb is one of the four main detectors at the Large Hadron Collider. Each of the LHC experiments has its own tasks, its own systems and solutions. The main direction of LHCb’s work is the study of B mesons containing beauty quarks. From here came the name of the detector: beauty quark in English – beauty quark.
