The world’s most-powerful accelerator “SuperKEKB” began its operation last month. We will livestream the moment of the 1st collision, when electrons and positrons meet for the first time with this newborn machine.

On last April, we livestreamed the unification of the SuperKEKB accelerator and the Belle II detector with commentary of scientists which took over eight hours. This time we will go beyond. Since no one know when the 1st collision might happen, we decided to livestream until then.

Keep your eyes open and let’s enjoy the delighted moment together !
