Upgrading the NA61/SHINE Local TPC Data Acquisition System

This document summarizes my work as a Summer Student in the NA61/SHINE experiment. I discuss the SHINE 2020 upgrades, specifically those to the TPC data acquisition system. I present the process for creating a flow of simulated data from the TPC readout electronics to online event reconstruction software currently being developed. This involved taking "real" data with cosmic rays, reading out that data, and decoding it to be read by the event reconstruction software. Additionally, I discuss the creation of a simulated trigger system for both hardware and software purposes. This work helps to ensure that, once SHINE is back in operation, the real-time event reconstruction software will work smoothly with the new readout electronics.
