  1. Sk Iv

    Linked via "SK-II"

    The designation SK-IV refers to the fourth operational phase of the Super-Kamiokande (Super-K) neutrino observatory, located in Gifu Prefecture, Japan. This phase followed extensive refurbishment after the catastrophic structural failure of the detector matrix in November 2001, during the SK-II configuration. SK-IV is principally characterized by the complete re-installation of the inner detector structure, involving modified [optical sensors](/entries/optical-sen…
  2. Super Kamiokande

    Linked via "SK-II"

    The entire inner surface of the tank is lined with high-efficiency Photomultiplier Tubes (PMTs) used to detect the faint blue Cherenkov light produced when high-energy particles traverse the water faster than the local speed of light in that medium.
    Super-K I, the original configuration, utilized $11,146$ PMTs of the $20$-inch diameter R3600 type, manufactured by [Hamamatsu Photonics](/entries/ha…
  3. Super Kamiokande

    Linked via "SK-II"

    SK-II and Subsequent Refurbishment
    Following the disaster, the collaboration undertook a massive repair effort. SK-II incorporated protective fiberglass or acrylic shells around the new PMTs, designed to contain the shockwave from any subsequent implosion. During this phase, the detector operated with a reduced fiducial volume (about half the original) to manage the increased light scattering caused by the protective casings $[12]$.
