Introduction to Bell Detector
The Bell detector is located at a collision point on the KEKB accelerator ring beam tube. The experimental building where it is located is called the Tsukuba Laboratory, which is a building with two floors and four floors underground. The size of the detector is about 8m x 8m x 8m (that is, a three-storey cube) and the weight is about 1,500 metric tons. It records various physical reaction processes after the electron collides with the positron.
