  1. Beamtime Application via DOOR 
    At latest 4 weeks in advance of your beamtime.
    • For regular proposals the experiment specification (beamtime application) is submitted together with the proposal to the corresponding deadline.
    • For LTPs and BAGs: Please login to DOOR as general user and select 'Follow-up applications for beamtime for a PETRA III long-term project' (LTP) or 'Submission of experiment specifications for BAG proposals at PETRA III' (BAG). Click on 'Submit' and fill in the form.
