SBN and ICARUS
Three detectors to measure the neutrino flux from the same BNB source at three different locations. By comparing the number of observed neutrinos and their energies at different locations, we can precisely measure the oscillation effect. MicroBooNE has taken data since 2015 and plan to complete in 2020. ICARUS and SBND plan to start data taking in 2020 and 2021 respectively. ICARUS is the largest among three, more than 5 times larger than MicroBooNE, and is responsible for detecting oscillated neutrino flux in both electron and muon flavors. SBND will collect the most number of neutrino interactions and provide an accurate flux estimate as well as crucial sample for studying neutrino-nucleus interaction modeling.
ICARUS Cryostat toward the end of its journey from CERN, Switzerland, to Fermilab, Illinois. This is one of two large cryostat that consist the ICARUS detector. Each cryostat holds 300-tons of liquid argon and 2 TPC modules.

Left: 3D point reconstruction in ICARUS detector using U-ResNet, a deep neural network to extract the pixel-level features. Different colors indicate different types of particles found by U-ResNet. The middle figure focuses in the region near the decay (Michel) electron from a muon, which is useful for calibrating the detector response for low energy electromagnetic showers. On the right, the pixel count per reconstructed Michel electron (data points), which is a measure of energy, is compared with the true spectrum (green bands).
