Abstract
The High Luminosity-Large Hadron Collider (HL-LHC) will reach an approximate pile-up of 200 collisions per bunch crossing, ten times more than the current Large Hadron Collider. Beginning operation at the end of the decade, it will accumulate 3000 fb−1, increasing the chances of observing new processes and allowing measurement of rare processes with higher precision. Moreover, the pile-up increase means more particle production, causing higher radiation damage and detector occupancy conditions. Therefore, the current tracking system in the ATLAS detector will be replaced by the new Inner Tracker system (ITk). ITk is based on silicon detectors, composed of individual sensors and readout electronics called modules. This project concerns... (More)

Popular Abstract
At the end of the 19th century, the only elementary particle known was the electron. However, this changed during the 20th century with the development of accelerator physics and the colliders. By the end of 20th century, all the fundamental particles predicted by the Standard Model were discovered except for the Higgs Boson. To discover the Higgs Boson, it was needed to build the Large Hadron Collider and wait until 2012, when the discovery was announced. One could think that with the discovery of the Higgs Boson the puzzle was resolved. However, this is far from reality as there are still fundamental questions to answer, such as the nature of dark matter. There are also hints of new physics beyond the Standard Model in the data analyzed... (More)
At the end of the 19th century, the only elementary particle known was the electron. However, this changed during the 20th century with the development of accelerator physics and the colliders. By the end of 20th century, all the fundamental particles predicted by the Standard Model were discovered except for the Higgs Boson. To discover the Higgs Boson, it was needed to build the Large Hadron Collider and wait until 2012, when the discovery was announced. One could think that with the discovery of the Higgs Boson the puzzle was resolved. However, this is far from reality as there are still fundamental questions to answer, such as the nature of dark matter. There are also hints of new physics beyond the Standard Model in the data analyzed from LHC. To continue this journey, the LHC will be upgraded into the High Luminosity LHC (HL-LHC). Starting operation by the end of the decade, this new upgrade will increase the number of collisions produced, allowing the production and detection of rare processes and even of new processes not detected yet. To detect these processes, it is also necessary to improve the detectors at LHC to keep up with the number of collisions. One of these detectors is the new Inner Tracker (ITk) at the ATLAS experiment. This detector aims to track the path of the charged particles produced in the collisions. More collisions mean more particle production and more radiation damage suffered by the detectors. Therefore, our detector has to be faster but also deal with the increase in radiation. ITk will be able to deal with these conditions thanks to the silicon detectors that comprise the detector. The silicon detectors that form ITk need to undergo a quality control process before installing them in the detector structure. Lund University is chosen as a testing site for thermal cycling the process. This process consists of warming up and cooling down the silicon detectors while they are electrically tested. To perform this test, the ITk collaboration has designed an environmental chamber, the so-called Cold Box. My master’s thesis consists of preparing the Cold Box received at Lund University to fulfill the requirements established by the ITK collaboration. (Less)
