As “Upgrade” is known the stage of modernization that’s happening the large Hadron of Collider (LHC) of the European laboratory CERN. A process in which physical University Santa Maria, together with other scientists in the world, are actively working. Operations of the large Hadron Collider, LHC, concluded in December 2012, and since then the majority of the members of the European Organization for Nuclear Research, CERN have worked to make improvements that enable to increase the energy of 8 to 14 Tera-electronvolts (TeV) collisions.
The technological scientific center of Valparaiso (CCTVal), the Universidad Santa Maria, has not been out of this fundamental process of improvement, working for ATLAS, the largest LHC detector. “This work is of utmost importance because we are getting a new fundamental understanding of the subatomic world. With this new knowledge, always come new technologies, which have economic and social benefits,”said Will Brooks, Doctor in physics and leader of the experimental high-energy physics, who along with Dr. Sergey Kuleshov, are preparing to contribute to the improvement of the ATLAS muon detector.
The project in which these scientists are committed consists of replacement of the so-called small wheel of muons, to offer increased muon tracking accuracy. This improvement would greatly reduce the rate of false signals and sharpen the threshold of trigger of these particles in an area that is currently weak. The muon detection helps significantly to find Higgs particles.
This “small wheel” isn’t really so small: will be made up of many parts of a detector totaling 800, forming a piece of one by two meters. Kuleshov and Brooks plan to build 100 of these pieces and his team. 2013 Will be a year of molding, to start building these parts in mid-2014. The objective is that these creations arrive in 2017 to CERN.
The Area of particle physics, CCTVal together with colleagues from the Catholic University are the only ones in the country working on this improvement. Meanwhile other laboratories working on muons are China and Israel. In the latter country is currently to learn about devices to implement the electronic Civil Engineer from the Universidad Santa Maria, Rimsky Rojas.
When Chile entered the ATLAS collaboration, the detector was already built, so from CCTVal participated in the operation and data analysis. This active cooperation, the demonstration of the capabilities of the physicists and facilities and equipment of high-quality laboratories, are the reasons why currently the Santa Maria University contributes to building parts of a detector in this historic “Upgrade” of CERN.
