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
Access restrictions due to the current situation with the spread of the corona virus.
Updated: 4th January 2021
The ASTRID2 facility is running again after several weeks of shutdown due to the global COVID-19 pandemic. Due to current restrictions we are still not able to offer beamtime to all users at this time. As restrictions are changed to allow travel to Denmark, users will be contacted in order to schedule beamtime for their experiments to go ahead. If you have any questions please contact the relevant beamline scientist.
We urge all groups to limit the number of users working at the beamline at any one time to two. Please also ensure that all users read the Rules for Using Research Labs at AU.
Despite the current restrictions, if you have a project which aims to advance research into COVID-19 we will accept proposals at any time and if feasible will allocate beam time to the project. If you have any questions, or would like to submit a proposal please contact .

Research at LEAPS facilities fighting COVID-19 LEAPS facilities are joining forces in front of the coronavirus pandemic, offering their capacities to the whole scientific community. SRCD at ASTRID2 is offered as a tool for this research
Call for proposals - Closed!
The call for proposals for beam time in 2021 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.
Remember the animation prepared by Coldvision Studio showing the injection and storage of electrons in ASTRID? Well a brand new animation has been prepared by Coldvision Studio which now includes ASTRID2 and the top-up injection process.
The images below are screenshots from the animation, but the full animation can be viewed here.

A Lego model of ASTRID2 with a scale of approimxately 1:15 has been built and is now on display at the entrance to the Department of Physics and Astronomy.
At first it was just an interesting project, to see if the Lego bricks available allowed us to reproduce the major elements of the ring in a recognizable way.
When we chose the colours of the magnets in ASTRID2 in the design phase, we specifically asked them to be the colours of Lego bricks, though not with making a model
in mind at that time, so colours weren’t a problem. The digital Lego model was added to and tweaked over several years until we decided that we should try and actually
make it. The model is made up of about 2500 pieces. Click here to view more photos of the model.

Analytical Research Infrastructures of Europe (ARIE) join forces to face COVID-19 and other viral and microbial threats.
ARIE, of which the ASTRID2 light source at Aarhus University is a member, have joined forces to publish a position paper where their plan to tackle the five Horizon Europe Missions is presented.
The final version of this position paper has now been released and can be viewed here.
A second ARIE joint position paper on “VIRAL and MICROBIAL THREATS”, has also been published (view here).
In 2020 despite disruption due to the corona virus pandemic, ASTRID2 provided 28 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.
The newest beam line, SGM4, has been commissioned and is awaiting the final installation and commissioning of the endstation.
In 2008 ISA was awarded money to build a new high brilliance synchrotron storage ring, ASTRID2. Construction of the ring began in 2011 and by April 2012 the whole ring was
under vacuum and ready for testing.
The first beam was injected into the ASTRID2 ring on
Monday 14th May 2012 and the first full turn of ASTRID2 was accomplished on Tuesday the 10th July 2012. On the 7th
of August electrons circulated the ring for almost 200 µs (1300 turns of the ring). On the 2nd of November
2012 a stored beam with RF was acheived for the first time. Commissioning of ASTRID2 proceeded well in 2013 and on the
13th of September 2013 200 mA of current was stored in ASTRID2 and top-up at 200 mA successful. In December 2013 the first external user came to do experiments on the AU-UV beam line.
2014 saw the commissioning of the AU-SGM3, AU-Matline and AU-CD beam lines, with all beam lines fully operational by mid 2014. In early 2016 the newest beam line, AMOLine, was commissioned.
