Belle II membership

In order to become a member of the Belle II collaboration refer to NewComers. After that, in order to access the Belle II collaborative services, which are hosted at DESY, you need an account. The procedure to obtain this account is described below.  Please read this page carefully and also see the warnings on the right before you proceed. 

Registration procedure

The standard  Belle II Registration procedure for official Belle II members is based on Grid user certificates. Step-by-step instructions to obtain and use Grid user certificates are in the lower part of this page. There are other possibilities though to register without a Grid user certificate. Please read ahead:

 

Belle II collaborators, who have (had) already a DESY account, may want to try out whether their account has already been enabled for Belle II by trying to log into bastion.desy.de. In case of problems please contact b2-registration-support_AT_belle2.org. See also the warnings on the right side of this page.

Belle II collaborators, who hold a Grid user certificates and are in the Belle II members list can go directly to the registration portal. Make sure the name fields are filled correctly (see warnings on this page on the right) and your e-mail address is consistent with the Belle II members list.

Alternatively, in particular for users who are not (yet) in the Belle II members list, a paper-based registration procedure is available.The two main steps of authentication ('Who are you?') and authorization ('Are you in Belle II?') have to be carried out manually. Therefore it will require more work from your side and from the administrators in your and our institute. Hence we would like to strongly encourage you again to go for the Grid user certificate based registration since you will need this certificate later on for accessing data and submitting jobs in the Belle II Grid anyway. See Belle II Paper-based Registration.

Students of Belle II who are not (yet)  in the Belle II members list must use the Belle II Paper-based Registration. Make sure the form is signed by your institute representative!

B2TiP (non-Belle II) members of the Belle II theory platform (B2TiP) please refer to Belle II Registration for B2TiP Users. Belle II members should contact Phillip Urquijo and b2-registration-support_AT_belle2.org to become members of this special group.

External (non-Belle II) members who needed access please refer to Belle II Registration for External Users.

Account creation

After your account has been created (it takes a few hours) you get further instructions by e-mail. Attention: Make sure those confirmation e-mails do not end up in SPAM filters! After that you have to change your initial password within the next 5 days on http://passwd.desy.de.

Your account is good for the Belle II internal web pages, the wiki (confluence), the issue tracker (jira), the GIT repository (stash), the build tool (bamboo), and the Mailing Lists .

Computing ressources (NAF)

DESY operates an Analysis Facility (NAF) which provides computing resources for Belle II users. In order to gain access to those resources please refer to Belle II Requesting Additional Resource Access.

At the bottom of the request portal you are asked to agree to the 'Conditions of Use for Information-Processing Systems at DESY'. The underlying document regulates the legal side of the usage of computers at DESY. The document is rather old and will be consolidated. Some links target on local users and are therefore internal. The document contains links to pages which are not relevant for abroad users, such as the local work council 'http://www.desy.de/betriebsrat'.

Common Problems:

You may find more answers in the (FAQ) section.

Make sure all names are reasonable. The portal might take unreasonable entries from your Grid user certificate, e.g. numbers or e-mail addresses in the name fields. The order of given / family name might be different, e.g. in Asia. Please correct, if needed.

Also make sure your e-mail address is consistent with the one on the Belle II member list and if applicable in the VOMS server.

After your new account is activated you get notified by e-mail (in a few hours). Change your initial password in time! Do not register again! One account / password is valid for for all resources!

Users who have already a DESY account (even an expired one) may want to try out first if they can use the the account. If in doubt, contact b2-registration-support_AT_belle2.org . Please do not register via the portal!

On any rate, never register twice as long as you are not explicitly asked for.
