Muon Telescope and TPC Data Analysis for mini-CAPTAIN

Creative Commons 'BY' version 4.0 license

Mini-CAPTAIN is a 400 kg liquid argon time projection chamber (TPC) and serves as a prototype for the 5 ton CAPTAIN detector. Cosmic muons are the primary data source for its commissioning phase. These particles are tracked by the muon telescope, consisting of multi-wire chambers for data collection and scintillator paddles for triggering. Telescope event reconstruction, track extrapolation into the TPC, and correlation of events between these two detector systems will be discussed. I will demonstrate that telescope events can be used to calculate which TPC wires are good candidates for seeing a muon signal. While a full muon track has not yet been seen in TPC data due to high electronic noise and insufficient liquid argon purity, the analysis programs detailed in this paper will expedite track finding once new data has been collected. This work can also be used to align the TPC before it takes data in a beam.
