SUMMARY:Performance Characterization of the IceCube Upgrade and Detect
 ion of First Neutrinos\, Preliminary Exam\, Delaney Butterfield
DESCRIPTION:The IceCube Upgrade is an extension of the existing IceCub
 e Neutrino Observatory and will be deployed in the upcoming 2025/2026 
 austral summer. The instrumentation volume\, consisting of seven new s
 trings\, will be 200 times more densely instrumented than IceCube to t
 arget lower energy atmospheric neutrino interactions. The additional s
 trings will feature new optical modules\, which will more than triple 
 the number of PMT channels in the detector. In this presentation\, I d
 escribe the new detector configuration and discuss my work on the low-
 level data flow. More PMT channels and more sensitive modules result i
 n a higher data rate up the long cables of the detector leading to the
  surface. To reduce this data rate\, we have introduced a new step in 
 the data flow known as the "Pre-Trigger." Unique to the Upgrade\, the 
 Pre-Trigger represents the first step in deciding which PMT signals to
  keep when building events. In addition to my work on the in-ice data 
 flow\, I will present my initial studies on characterizing the early d
 ata we expect to see from the new strings\, and my work towards perfor
 ming a full analysis of a detector verification and commissioning samp
 le of new data from the IceCube Upgrade. This analysis will highlight 
 atmospheric neutrino events in the 3-50 GeV energy range which we woul
 d not see without the Upgrade\, and how this early dataset will set th
 e stage for future analyses.
