EU support programmes

CALIPSOplus - Convenient Access to Light Sources Open to Innovation, Science and to the World

The Trans-national Access programme of the project CALIPSOplus - funded by the European Comission within the EU Framework Programme for Research and Innovation H2020 - supports access for European researchers to European and Middle Eastern light sources.

The project runs from May 1, 2017 to October 31, 2021.


HZB is member of a network of European and Middle Eastern synchrotron and free electron laser facilities – the "Convenient Access to Light Sources Open to Innovation, Science and to the World" (CALIPSOplus).

CALIPSOplus is a consortium of 19 partner organisations from 12 countries, involving a total of 14 synchrotrons and 8 free electron lasers totaling up to 82 500 hours of available experimental time.


In the framework of the Trans-national Access programme of CALIPSOplus, HZB has received funds foreseen for support of external HZB users coming from EU Member States or Associated States.

These EU funds give free access to the HZB synchrotron facility BESSY II and provide support for travel and subsistence expenses for a maximum of two young scientists per experiment. For more information, please refer to our funding arrangements.

Twinning programme

CALIPSOplus dedicates particular attention to leveraging scientific excellence in EU-13 countries and to widening the use of light sources by users from these regions. To this effect, a Twinning programme has been set up to partner potential users with host groups that could share their know-how and expertise in applying the available experimental techniques to common research areas.

  • For Twinning guests:

Twinning guests will benefit from free access to the light source, full coverage of travel and subsistence costs, training in how to use the facilities and in executing a beamtime, discussion and support in writing own proposals, direct contact to the facilities and the opportunity to strike new research collaborations.

Please fill-out your Twinning guest profile form so we may match you with the most suitable host.

  • For Twinning hosts:

Becoming a Twinning partner will give you the opportunity to strike up new and exciting collaborations with mentored european research groups. Please fill-out your Twinning host profile form so we can find the best scientific match amongst our interested applicants.

Please note: one member of your team will be eligible to receive travel and accommodation support for the beamtime during which you host a Twinning partner, in addition to whatever financial support you might already be benefiting from.

Any questions regarding funding of Twinning guests and hosts should be directed to Ana Sofia Anselmo.

Obligations as CALIPSOplus-funded users

In any publications resulting from user projects funded through CALIPSOplus, the acknowledgment of this support is mandatory. The following paragraph must be included in the acknowledgments section:

The research leading to this result has been supported by the project CALIPSOplus under the Grant Agreement 730872 from the EU Framework Programme for Research and Innovation HORIZON 2020.

Please note: All publications resulting from work done in the HZB should be registered in GATE and a final version of the manuscript or a copy of the published paper should be uploaded to the network. Open access publication of results from work funded by the EU Commission programs within the Horizon 2020 framework is highly encouraged. CALIPSOplus offers financial support in publishing open access - check here for more information.

User group survey (EU database)
After the experiment, funded users are requested to complete a questionnaire directly in the European Comission's official survey management tool.

  • concerning question n° 1 of the questionnaire:
    The required EC Contract number for all supported proposals is 730872.
  • concerning question n° 2 of the questionnaire:
    Your User Project Acronym is your proposal ID, easily found in your GATE account.

Data protection

Users are required to provide some personal data, which will be recorded and used for the following purposes only: The data will be processed for funding, statistical and administrative purposes connected with their research, and to statistically analyse the membership of the synchrotron user community.

Data is collected by the CALIPSOplus project manager on behalf of the European Commission, and therefore may be accessed by the CALIPSOplus project coordinators and the European Commission for official use only, and will remain confidential. The personal data will be kept safe and secure and will not be shared with other organisations without the knowledge of the users, unless this is required by law. If an email address is requested by the EC, this is solely for the purpose of conducting a mid-term review if necessary, and it will not be divulged to any third party, or used for marketing purposes.
