When the pre-registration (PRT) has been completed for a new User, it is now possible to get a CERN computer account and, hence, complete the on-line safety courses required for access to ISOLDE before coming to CERN. Once the pre-registration is accepted by the CERN Users office an email is sent to the User informing them how to apply for the account. The User must still go to the Users office when they arrive at CERN to complete their registration and if they do not come to CERN and sign their contract, their computing account will be deleted within 30 days of their planned arrival.
