Apply for Beamtime

New users are always welcome. The HZB Beamtime Coordination and HZB User Office are the major points 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.


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.

  • Beamtime applications for BESSY II, MX and EMIL may only submitted via the general access tool GATE
  • Please find a list of available instruments here
  • A guide for beamtime application can be found at our webpage or as a printable version Guidelines
  • NO deadline for CXR proposal. Applications for experiment time for the X-Ray CoreLab at Adlershof can be submitted via GATE at any time.


The HZB User Coordination kindly invites you to submit beamtime applications for the proposal round 2022-I for the synchrotron facility BESSY II, the MX beamlines and the facility EMIL.

  • Beamtime will be allocated in the time period January 2022 to May 2022
  • Deadline: 1 September 2021, 23:59 (CET)
  • BESSY II beamtime applications may only submitted via the general access tool GATE
  • Please find a list of available instruments here
  • A guide for beamtime application can be found at our webpage or as a printable version Guidelines
  • More detailed information on the recent call can be found at CALL 2022-I

From proposal round 2022-I resubmission of former proposal is no longer possible. FOLLOW UP will be used instead of resubmission and gives you the opportunity to continue a previous project (more information).


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 below. All users applying for synchrotron radiation beamtime are requested to choose the appropriate Scientific College for their proposal upon online submission. The rules of procedure of the HZB Scientific Selection Panel are available here. A list of all current college members can be found here.

Colleges - Scientific Selection Panel (SSP)


C1. Soft Condensed Matter, Biology, Life and Health Science

Research fields/topics

  • disordered matter, glasses
  • soft condensed matter
  • bio-inspired materials
  • biophysics
  • pharmacology/drug development
  • medicine/therapeutics
  • nutrition safety
  • zoology
  • palaeontology

College C1 reviews proposals dealing with soft matter and bio-inspired materials. Topics include structure, dynamics and kinetics in the bulk and at interfaces. In addition it reviews radiobiology- and radiotherapy-related proposals. Projects concerned with biophysical questions or palaeontological samples are assessed in this college as well. Proposals dealing with confined geometry effects may also consider college C6 (material sciences and hard condensed matter).


C2. Macromolecular Crystallography (MX)

Research fields/topics

  • molecular biology
  • structural biology

College C2 (MX-College) primarily deals with proposals related to macromolecular crystallography (e.g. protein structure determination).


C3a Surfaces and Interfaces, thin films (non-magnetic, no catalysis)

Research fields/topics

  • surfaces
  • interfaces
  • thin films

College C3a reviews proposals related to surface chemistry, thin films and interfaces. The emphasis is on morphology, structure and (electronic) interactions in these systems.


C3b Chemistry, Catalysis and Diluted Matter Research

Research fields/topics

  • chemical reactions, phase transitions
  • structure, state, composition of substances of chemical relevance
  • nano-chemistry
  • catalysis, reaction pathways
  • chemistry of water, liquids and gases
  • atomic and molecular physics
  • small clusters
  • research on substances of astrophysical, atmospheric and environmental relevance

College C3b reviews proposals related to structure, state, composition and reactions of substances, including chemical crystallography. Pathway and dynamics of chemical reactions as well as catalysis are a further focal point for this college. Proposals from the fields gas phases, liquids, solutions and small clusters will be discussed here too. Proposers aiming primarily at crystallographic or structural investigations are encouraged to consider college C6 (material science and hard condensed matter).


C4. Electronic Structure (not magnetism)

Research fields/topics

  • solid state physics
  • thin films
  • mesoscopic objects (clusters, nanoparticles)

College C4 reviews research projects dealing with the investigation of electronic structure of matter, primarily with spectroscopic methods. For projects with emphasis on magnetism college C5 (Magnetism and Superconductivity) is recommended.


C5. Magnetism and Superconductivity

Research fields/topics

  • magnetic structure
  • electronic structure of magnetic materials
  • quantum magnetism
  • magnetic dynamics
  • spin dynamics
  • molecular nano-magnets
  • superconductivity

College C5 reviews research projects with emphasis on geometric and electronic structure of magnetic materials, magnetic effects and magneto-dynamics.


C6. Material Sciences and Hard Condensed Matter (no spectroscopy)

Research fields/topics

  • nano-structured materials
  • engineering/industrial materials
  • residual stress/strain
  • novel materials
  • applied materials
  • coatings
  • mesoscopic structures
  • earth science related materials
  • crystallography

College C6 reviews proposals related to fundamental materials science/novel materials as well as to materials of industrial or engineering relevance. Projects concerning geological questions or chemical structures/crystallography are be addressed in this college. Topics from micro-electronic relevance are discussed in this panel.
