Visiting the ASTRID2 facility
The ASTRID2 facility
The figure below shows a overview of the ASTRID2 facility.
Overview of the ASTRID2 facility, showing both the booster ASTRID and the ASTRID2 ring. The green areas are surrounded by a concrete wall and are not accessible when the ring is operational.
The beamline areas outside the concrete wall surrounding the ASTRID2 ring are always accessible (see the image above), but the area indicated in green is not accesible when the ring is in operation, due to high levels of radiation.
Status of ASTRID2
The current status of the ring can be found here. On this page you will find the status of the beam, which operational mode the ring is currently in and whether access into the restricted (green area) is possible.
Operational modes
User beam
Throughout the year, for approximately three weeks out of every four, the ring is in normal operation, providing a "user beam" for the experiments. During this time the ring area, behind the concrete walls, is not accessible. You can visit the ISA schedule page to see when there is user beam.
Machine Physics
Usually for one week, between user beam periods. During machine physics the ring halls are generally closed, however there may be an opportunity to visit the rings if repairs or upgrades are being made to the facility. Check the ISA status page to see if the ring halls are open.
Shutdown periods
A few times a year we have one or two weeks where the ring is in shutdown mode, this allows major upgrades or hardware development to be carried out. While in shutdown mode the ring hall is open and you may visit the ring at any time.
You can see the open or closed status of the rings around the facility, there are "traffic lights" at all doors into the rings.
If the doors are closed and the light is either RED or YELLOW - DO NOT OPEN the door as ASTRID2 is running. Opening a door while in this state will cause the electron beam in the ring to be dumped.
The main door into ASTRID2. The RED and YELLOW state of the lights by each door to the restricted areas.
If the light next to the door is green then ASTRID2 is off and you may enter the ring area.
The main door into ASTRID2 open. The GREEN state of the lights by each door to the restricted areas.
Viewing platform
While the ring halls are closed it is possible to see over the concrete wall to the ASTRID2 ring from the viewing platform, the location of which is labelled and circled on the overview image at the top of the page.
The view of ASTRID2 from the viewing platform
There are occasions during machine physics when it is not possible to access the platform due to higher radiation levels. When this is the case a chain and sign will be placed across the entrance to the platform (right image below).

Tours of ASTRID2
ISA welcomes visitors to the Danish light source, ASTRID2, and to see the experiments which utilise the high brilliance light.
Guided tours.The IFA visitor service has a team of guides who can show groups around the beam line area and give a general introduction to the light source and the science being carried out. Visit their webpage to find out how to arrange a tour of ASTRID2 and other areas of the Physics department.
If you would like to see the ring itself (the green shaded areas in the image) then this is dependent upon the operational mode. You can see the status of the ring and the operational mode on the ISA website at http://www.isa.au.dk/status. On the status webpage you can also see if the ring halls are currently open.
Contact Information
Operators at ASTRID2
If you have a question regarding ASTRID2 or there is a problem please contact one of the operators. On weekdays there is typically an operator at the Institute until ~17:00, after this time there is no one officially on duty, but you can try to contact one of the operators.
