ISA is a Danish National Facility where research is carried out over a wide range of the natural and life sciences, including fundamental physics, material science, molecular biology and laboratory astrophysics, using accelerators and storage rings. |
Access to ISA
Call for ISA proposals - Closed!
- The call for ISA proposals for beam time in 2025 is closed. However if you are interested in applying for beam time on one of the ASTRID2 beam lines, then it may still be possible. Please read the information contained in the link below and contact the relevant beam line scientist to see if there is time available.
ISA welcomes applications, from national or international groups, for access to any of the ISA research facilities.

Support for TNA to ASTRID2 through NEPHEWSWith a special focus on users from EU widening countries, Ukraine and from countries without direct access to large scale research infrastructures in their country, it is possible to apply for TNA through the Horizon Europe project NEPHEWS. Applications for this support are accepted as part of ISA's annual call for proposals, and is applicable for access to all facilities on ASTRID2 |

August 2025 | The first visit to ASTRID2 under the NEPHEWS Twinning programme has taken place. |
We are pleased to announce the successful completion of a visit to the ASTRID2 synchrotron light source (operated by ISA at Aarhus University in Denmark) under the NEPHEWS Twinning programme. The goal of this EU supported initiative is to “twin” experienced researchers with those who would like to learn, not only about a specific technique and how it may be applicable to their research, but also the process involved in applying for and carrying out a successful beam time. Under this programme, Dr Berkan Atman from Middle East Technical University in Ankara, Turkey, joined an experienced local group, whose project “Shifts of the Mg 2p, Si 2p, and O 1s core-levels as a function of Mg-to-Si ratio in Mg Silicates on HOPG” had been awarded beamtime on MatLine. During the beam time, where Dr Atman was able to take on the role of a main operator of the experiments, the collaboration enabled advanced hands-on training, data collection, and knowledge exchange, significantly enhancing the research capacity and fostering future cooperation between institutions. The project marks a meaningful step toward strengthening scientific excellence and innovation through shared infrastructure and expertise and, importantly, improving accessibility to these research infrastructures. |
May 2025 | The Nephews project offers virtual training events for newcomers in the usage of large-scale Research Infrastructures. |
During the course of the project, Nephews will conduct four cycles of two-days of training in the following fields:
Access to the virtual training events is open to everyone and there is an opportunity for Q&A during the live events. To find out more and register to take part in a virtual training event, visit the NEPHEWS website.. |

ASTRID2
Current status
In 2024 ASTRID2 provided 35 weeks of user beam time to the 6 operational beam lines, with normal operation at 180 mA top-up. Machine physics studies are ongoing in order to improve stability and lifetime of the beam.
