ATLAS is one of the four major experiments at the Large Hadron Collider (LHC) at CERN. It ia general-purpose particle physics experiment run by physicists from all around the world. ATLAS physicists test the predictions of the Standard Model, which encapsulates our current understanding of what the building blocks of matter are and how they interact. These studies can lead to ground-breaking discoveries, such as that of the Higgs boson, physics beyond the Standard Model, and the development of new theories to better describe our universe. ATLAS is made up of many different instruments and subsystems, and this research focuses specifically on the Muon Spectrometer. Specifically within the Muon Spectrometer, this research analyzes data from Monitored Drift Tubes (MDTs). In short, muons are one of the very few things that get through the first three detectors within ATLAS, and MDTs work to trace the curved path of the muon as it passes through, which then allows for the calculation of its momentum. MDTs are filled with gas, and as the muon passes through a number of tubes, it leaves a trail of charged electrons that drift to the center of each tube. Recording the time of this drift process is what leads to the tracing the muon’s path. The goal of this research is to understand the issues that may develop in these drift tubes while everything is running and data is being taken. An example of this is a Single Event Upset (SEU). SEUs occur when a large energy deposition from one of the charged particles disrupts the functioning of the electronics, specifically, a state change of a logical element (a memory bit). The study will produce and compare a large variety of histograms from the beginning and ends of runs, and checking for any discrepancies. The research will look at different types of issues and their frequencies in 2018 proton-proton collision data.
