Getting Access to the Belle II Collaborative Services and Tools

In order to make use of the Belle II collaborative services (B2CS), users must  request login credentials from DESY. They are good for ALL Belle II services at DESY but are completely independent of any KEK account. Please refer to the Belle II User Registration. Also see Belle II Registration Frequently Asked Questions (FAQ) / Trouble Shooting.


Belle II Wiki

The content of the former KEK Belle II Twiki is now in two pages. The publicly viewable Belle II Public WebHome and the restricted Belle II Internal Wiki. The latter is visible to Belle II users only. Please find the login at the top right and use your Belle II account.

If you need technical support on confluence beyond the documentation, please contact the e-mail address
