Apply for Beamtime

New users are always welcome. The HZB User Coordination is the major point of contact for all current and prospective users of the HZB user facility BESSY II. Please do not hesitate to contact us for administrative help or support. Together with the HZB instrument scientists we can help you with your beamtime application or your stay at BESSY II. All HZB users receive a high level of support during beamtime. For more detailed information on the Proposal Submission process click HERE.


Twice a year the HZB User Coordination welcomes the submission of proposals for the large scale facility BESSY II, the MX beamlines and the facility EMIL. Applications for experiment time for the X-Ray CoreLab at Adlershof can be submitted via GATE at any time (NO deadline for CXR proposal).

The HZB Scientific Selection Panel (SSP) assesses the scientific merit of beamtime applications and gives recommendations for beamtime allocation. The decision is based solely on the information given in the proposals and, if applicable, on results, experimental reports and publications related to previous HZB experiments. The HZB Scientific Selection Panel is organised in Scientific Colleges, which have been grouped according to research fields, in order to facilitate discussions on the scientific merit of the proposals. More detailed information on these colleges can be found HERE. All users applying for synchrotron radiation beamtime are requested to choose the appropriate Scientific College for their proposal upon online submission.
