DUNE will be the world's largest neutrino experiment due to take data
in 2025. Here is described the data acquisition (DAQ) system for
one of its prototypes - ProtoDUNE-SP due to take data in Q4 of 2018.
ProtoDUNE-SP also breaks records as the largest beam test experiment yet
constructed, and is a fundamental element of CERN's Neutrino Platform.
This renders ProtoDUNE-SP an experiment in its own right and the design
and construction have been chosen to meet this scale. Due to the
aggressive timescale, off-the-shelf electronics have been chosen to meet
the demands of the experiment where possible. The ProtoDUNE-SP cryostat
comprises two primary subdetectors - a single phase liquid Argon TPC and
a companion Photon Detector. The TPC has two candidate readout solutions
under test in ProtoDUNE-SP - RCE (ATCA-based) and FELIX (PCIe-based).
Fermilab's artDAQ is used as the dataflow software for the experiment.
Custom timing and trigger electronics and software are also described.
Compression and triggering will take the ~480 Gb/s of data from the
front-end and reduce it sufficiently to 20 Gb/s bandwidth to permanent
data storage in CERN's EOS infrastructure.
