ATLAS is an experiment of major importance located in the Large Hadron Collider (LHC), a tunnel in the shape of a ring, 27 kilometers in diameter where particles travel at a great speed, colliding against each other.

After the Higgs Boson discovery at ATLAS, through the impact of proton beams at very high energy, it was confirmed the final piece needed to stablish the standard Model´s validity of fundamental interactions.

Following this scientific achievement, ATLAS started a continuous upgrade and reinforcement process and energy increase to 14 TeV. The main objective being the update of the collecting system and the data analysis from different collisions.


The Scientific and Technological Center of Valparaiso has been part of this modernization through the manufacturing of parts, for which CCTVal will contribute 140 individual detectors that will be fully molded and developed in the Experimental High Energy Physics laboratory, also known as Silab.

Subsequently they will be assembled and will become part of the Large detector in the Muon Small Wheel. The parts that will be manufactured correspond to the so called small-strip Thin Gap Chambers (sTGC) and their function is to detect muons in a precise way. Each one of the sTGC has a trapezoidal shape that measures around 1.2 meters long by 1.2 meters wide and 6 millimeters thick.

In addition to Chile, this project counts with the collaboration of Israel, Canada and China, meanwhile E.E.U.U will be in charge of the data acquisition electronics.
