Allen-Bradley 440H-P03035

The 440H-P03035 part number is linked to the ProtoDUNE-SP liquid argon time projection chamber, a cutting-edge single-phase detector serving as a prototype for the Deep Underground Neutrino Experiment (DUNE). Located at the CERN Neutrino Platform, this sophisticated detector plays a crucial role in studying neutrino interactions by identifying charged particles like pions, kaons, protons, muons, and electrons. With an impressive active volume of 7.2 × 6.1 × 7.0 cubic meters, the ProtoDUNE-SP is designed to function efficiently within a temperature range of 86.9 K to 88.2 K and operate at pressures between 970–1100 millibars. The engineering of the detector allows for a maximum design gauge pressure of 350 millibars, and it maintains an average heat leak of about 8 watts per square meter to ensure the stability of the liquid argon. Installed in an environment that delivers charged particles ranging from 0.3 GeV/c to 7 GeV/c, the ProtoDUNE-SP’s design is pivotal for evaluating neutrino data quality and advancing research in particle physics.
