April 11th, 2017 The Belle II detector was "rolled-in" to the collision point of the SuperKEKB accelerator The High Energy Accelerator Research Organization (KEK) successfully completed the "roll-in" of the Belle II detector on the afternoon of Tuesday April 11th. This is an important milestone for the international Belle II collaboration and the SuperKEKB accelerator. The Belle II experiment is an international collaboration with 23 member nations hosted by KEK in Tsukuba, Japan. Using a state-of-the-art experimental apparatus, Belle II explores the mysteries of the beginning of the the universe. The Belle II detector precisely measures elementary particle interactions artificially created with the upgraded SuperKEKB accelerator.
