N-Lab open tour was given on 10 June at the 64th Meidai Festival. The tour's theme was "Exploring particle physics with cutting-edge particle accelerators". Laboratory staff and students explained the confirmation of Kobayashi Maskawa's theory at the KEKB accelerator/Belle experiment and the discovery of the Higgs boson at the LHC accelerator/ATLAS experiment. Detectors, circuit boards, and computers for the experiments were displayed. Photos are available here. We thank the participants and hope they enjoyed the tour.
