The ATLAS experiment at the Large Hadron Collider at CERN is looking to improve on their previous discovery of the Higgs boson in 2012 with the discovery of new particles. To ensure the continued success of ATLAS, there are a series of planned upgrades to the detector. After the Phase II upgrade, scheduled for 2026, the ATLAS detector will receive collisions of proton bunches every 25 ns with an average of 140 interactions per collision. Most of these interactions are not energetic enough to produce interesting physics (high energy events). The uninteresting interactions are referred to as pileup. These pileup interactions happen simultaneously with the interesting events, leading to a masking of the signal beneath the pileup. In order to sift through the large amounts of data, a firm understanding of pileup is needed. The focus of this study is to measure the energy deposited in the detector due to pileup and use it as a discriminating factor in reducing the data flow to a rate that can be written out in the time allotted.
