HZB Safety & Access regulations

In order for experimentalists to make full use of the user facilities at HZB they must first make sure that they adhere to several safety and access regulations.


Please make sure to meet the Radiation Protection Regulations. Additionally two online trainings are mandatory.

For experimentalists:

Both the on-line radiation protection training and the online safety training are available from within GATE. You need to have a valid GATE account in order to be able to access the on-line briefings.

For other visitors to BESSY II:

Please use the following links to complete the online radiation protection training and the online safety training before traveling to BESSY II.


The process to meet the regulations mentioned on this page might take quite some time. We recommend to take the appropriate steps 3 months prior to your experiments. We also recommend to do the online trainings at least 3 weeks prior to your planned experiments

Security Check concerning the German Law on Foreign Trade (AWG)

For legal reasons the access to both HZB campuses is subject to certain restrictions for citizens from non-EU, non-OECD and non-NATO member states and the countries listed in the update version of the German Foreign Trade Regulations (AWV). In addition, according to recent restriction by the European Commission HZB is following the EU restrictive measures for Iran with effect on persons with Iranian citizenship. In case you are not sure about the status of your home country, you may check with the List of countries with no AWG restrictions or contact the user office.

In order to enable the access to HZB we need from everybody, who intends to take part in an experiment at HZB and who falls under the above mentioned restrictions, the following items:

  • short curriculum vitae (up to date!)
  • copy of passport (incl. photo, passport number) and visa (if applicable)

As a member of an experimental team you will find the information if an AWG check is necessary or not  in GATE. Please log into your GATE account and look up the "Prepare beamtime" section.

Please note:
An up-date of your documents needed for the AWG check, or a short statement in case there weren't any changes since your last visit to HZB, is required for every new visit.

For help or assistance with the safety & access regulations, please do not hesitate to contact the HZB User Offices for neutrons and photons.
