Welcome on the CTA registry web page. This is an application for the internal use of CTA members and collaborators.
If you are already a registered CTA user (i. e. you have an account), you can log into your personal space. There you can also reset your password, in case you forgot it. As a new CTA user, you can request an account, under the condition that you have been officially registered with CTA by your group leader (in the official CTA members list on the collaboration portal - if not or if you are not sure, you may want to contact the group leader of your institute beforehand).
