Outline of the Detector

Water tank

The Super-Kamiokande detector consists of a cylindrical stainless steel tank, 39.3m in diameter and 41.4m in height, and photo sensors called photo-multiplier-tubes (PMTs) installed to the detector wall. The detector is filled with 50 ktons of pure water.

 

The PMT support structure divides the tank into two distinct, optically isolated volumes, the inner detector (ID) and the outer detector (OD). The inwarded PMTs are installed to the ID wall and the outwarded PMTs to the OD wall.

 

The tank must be kept close because we must take data continuously. The photographs inside of the tank were taken during the construction and reconstruction period.
