This photomultiplier tube representa Takaaki Kajita's research at the Super-Kamiokande underground facility in Japan. The facility is a collaboration between several nations. This photomultiplier tube belongs to a part managed by the US.
Takaaki Kajita donated the photomultiplier tubes to the Nobel Prize Museum in 2015.
This photomultiplier tube represents Takaaki Kajita's research at the Super-Kamiokande underground facility in Japan. At the Super-Kamiokande, physicists study neutrinos, some of the smallest particles in the universe. The detector consists of a large water-filled container with walls lined with photomultiplier tubes. Neutrinos exist in large quantities but very rarely react with other particles. When they hit a particle in the Super-Kamiokande, this generates a small flash that can be detected and amplified by the photomultiplier tubes.
Takaaki Kajita donated the photomultiplier tube to the Nobel Prize Museum in 2015.
