A picture of the nuclear emulsion detector from beam upstream and the schematic side view of the detector. Metallic plates (1-mm^thick lead or 0.5mm-thick tungsten) are interleaved with 0.3 mm-thick emulsion films. A 14 kg lead module(left) and a 15 kg tungsten one(right), the volume about (20cm)3 for each.<\/figcaption><\/figure>\n

There could be new discoveries at the new frontier. Here the observation of neutrino interaction candidates from LHC is reported and it opened the door to study neutrino interactions at un-explored energy (sub-TeV to TeV) region.
\nWe are looking forward to seeing the outcome from the FASER experiment run in 2022-2024. The nuclear emulsion techniques developed at Nagoya University acts as a key role of neutrino detection and the analysis. \u2013 Osamu Sato<\/p><\/blockquote>\n
