The SBND experiment, a 112-ton liquid argon time projection chamber (LArTPC), functions as
the near detector for the Short Baseline Neutrino (SBN) program at Fermilab. Positioned only
110 metres from the beam target, SBND anticipates capturing over a million neutrino interactions
annually, surpassing the dataset sizes of other LAr experiments by more than an order of magnitude.
Due to its location on the surface, the detector is also exposed to high rates of cosmic rays, and
therefore the experiment necessitates a sophisticated and dependable trigger system to allow for
effective downstream analysis. This talk will detail the SBND hardware trigger system and its
performance with first data.
