NA61/SHINE is a fixed-target experiment operating at the SPS accelerator at CERN. The physics programme of the experiment was recently extended by open-charm measurements, requiring a major upgrade of the experimental facility during Long Shutdown 2. The main goal of the upgrade is to increase the event flow rate from 80Hz to 1kHz using readout electronics from the ALICE Collaboration for the NA61/SHINE main tracking detectors (Time- Projection-Chambers - TPCs). The precision of interaction vertex reconstruction will be significantly increased by the installation of the new Vertex Detector. The Time-of-flight detector and Calorimeter are being modernised as well. Those changes required the development of a new Trigger and Data AcQuisition (TDAQ) system.

This seminar will introduce the NA61/SHINE experiment and the main points of the currently ongoing upgrade. The new Data Acquisition System, optimized for high data rates, will be discussed, as well as the prepared online data filtration algorithms.
