Call for Proposals


The HZB User Coordination is welcoming the submission of proposals for the large scale facilities BESSY II and BER II.

Next round: Beamtime allocation in 2018-I

Submission is open

Next deadline for submission: September 1st 2017

Proposal submission

Beamtime applications have to be submitted by using the online General Access Tool (GATE).

Users not yet registered in the HZB user data-base will have to do so before being able to apply for beamtime or to be included as a co-proposer.

For guidance in writing a proposal please refer to the Guide for beamtime application.


The HZB Scientific Selection Panel (SSP) assesses the scientific merits of beamtime applications and gives recommendations for beamtime allocation. The decision is based solely on the information given in the porposals and, if applicable, on results, experimental reports and publications related to previous HZB experiments.

The next meeting of the SSP will be in October 2017.

Instruments on schedule




From August 2012 on the BESSY II experimental hall in total will be a controlled area  for radiation safety reasons.

Please refer to the Top-Up radiation safety requirements for more information.
