Description
We present a brief description of the Short-Baseline Near Detector (SBND) hardware trigger
system. The SBND experiment is a liquid argon neutrino detector that sits on the central axis of
the Booster Neutrino Beam (BNB), located at Fermilab. The detector is currently being assembled
and is expected to start operating in 2023. Neutrinos delivered by the BNB will interact with liquid
argon inside the SBND, producing charge and scintillation light that will be collected, respectively,
by the charge collection wires and the photon detection system. SBND will record over a million
neutrino interaction events per year while simultaneously being exposed to a large flux of cosmic
ray interactions. Thus it is imperative to determine which events in the detector are of interest
for analysis. This is the work of the SBND trigger system which receives several prompt inputs,
discriminates these inputs and qualifies them to form a so-called “trigger decision”. In this work,
we will focus on the general overview of the trigger system for SBND and, specifically, we describe
the configuration of the Analog Master Trigger Card used in the photon detection trigger.
