Phase 2 of the Belle II experiment is about to begin. A new super-B factory facility, utilizing the SuperKEKB accelerator and the Belle II detector, is designed to search for as yet unknown "New Physics".
The outreach teams of KEK and the Belle II collaboration worked together for more than a year to make the Belle II/SuperKEKB project better known in Japan as well as in the world.
Significant milestones in our roadmap are:
(1) the start of Phase 1 in Feb. 2016 and first turns in the SuperKEKB accelerator,
(2) "the Belle II roll-in", integration of the detector and the accelerator in Apr. 2017, and
(3) Phase2 and first collisions in the coming months,
the list will go on as the project develops towards its design luminosity.
In this talk, we will focus on "the Belle II roll-in" .
We cooperated with the "Niconico" livestreaming service in Japan and live-casted the roll-in event from the Belle II experimental hall for over 8 hours.
We would like to share know-how on how we collaborated, how we risk-hedged , and how impressive it was, and exchange opinions with other institutions who have tried livecasting important events.
