VERAcore
For all isotopes that can be detected at VERA, we provide measurements for the international scientific community. In general, we have to ask for a contribution to the costs (price list for measurements at VERAcore as of January 2024).
For free-of-charge measurements, see support by the HEAS research platform or by our EU-funded projects ChETEC-INFRA and ReMade@ARI.
You can also apply to our VERAcore Seed Grants for free-of-charge pilot AMS measurements two times a year: 1st May and 1st November.
For requests regarding measurements, including special discounts (e.g., HEAS research platform) please contact directly:

FAQ’s:
-
Is there any possibility for free-of-charge AMS measurements at VERA?
Yes! Two times a year you can apply for VERAcore Seed Grants. Two proposals are funded in every call: one for 14C (including sample preparation) and one for non-14C projects (not including sample preparation).
It is also possible to have free-of-charge analyses of your samples:
- for partners of the HEAS research platform, special conditions apply for radiocarbon measurements. The platform also offers you the possibility of applying to the HEAS Seed Grants.
- in the context of astrophysics via the Horizon 2020 project ChETEC-INFRA: Chemical Elements as Tracers of the Evolution of the Cosmos - Infrastructures for Nuclear Astrophysics. You must not be affiliated in Austria, and a positive evaluation of a proposal is needed, too.
- in the context of development of materials for a circular economy via the Horizon Europe project ReMade@ARI: Recyclable Materials Development at Analytical Research Infrastructures. You must not be affiliated in Austria, and a positive evaluation of a proposal is needed, too.
-
Can I have my samples prepared by the VERA lab staff?
Yes! Please contact the person in charge of the measurements of the radionuclide (see table at the top of this page) to discuss the details in advance.
-
Can I do sample preparation myself at the labs in Vienna?
Yes! We are hosting people to perform their own sample preparation at our labs under our guidance (e.g., 10Be, 26Al, 41Ca, actinides). There might also be an option to use the 36Cl lab at the BOKU in Vienna, which is run by Stephanie Neuhuber.
Generally, this is not the case for 14C, since the chemical preparation for these samples is performed by our staff.
-
Which is the deadline for submitting samples and when is the next measurement period (i.e., beamtime) for which nuclide?
We don’t know (yet)! We have a very flexible beamtime planning depending on technical issues and other demands (scientific, human resources, conference and PhD deadlines,...).
If you have samples ready, this is, already pressed in cathodes, please send them as soon as possible. At the latest, we would like to have them before Friday morning the week before beamtime starts for a specific nuclide to be most efficient.
If you send the samples to be pressed at VERA, then they have to be sent well ahead.
Please contact the person in charge of the measurements of the radionuclide (see table at the top of this page) to discuss details in advance.
-
Do I have to come to Vienna for the measurement?
No. But please contact the person in charge of the measurements of the radionuclide first (see table at the top of this page). You can send samples to the following address:
University of Vienna
Faculty of Physics
Isotope Physics
VERA Laboratory
Waehringer Str. 17/Hoftrakt (“Hoftrakt” means it is the backyard house)
1090 Vienna (Austria)
For sending samples, please see information about cathode, binder and references (table before the FAQ in this page).
-
How do I find the VERA laboratories?
The address is:
University of Vienna
Faculty of Physics
Isotope Physics
VERA Laboratory
Waehringer Str. 17/Hoftrakt (“Hoftrakt” means it is the backyard house)
1090 Vienna (Austria)
Arriving by train:
From the main train station (Wien Hauptbahnhof), you use the exit “Karl-Popper-Strasse” and take the tram D to “Schottentor”. You go one level below street level and take one of the trams to “Schwarzspanierstrasse” (1 stop only). You walk in the direction of travel (crossing the road), cross the road to the opposite side. If you are in front of the restaurant “VinziRast” you turn left and walk into the backyard. There is a wooden door with a bell next to it on the right you should ring (yes, the red button! “Glocke” is German for bell).
Arriving by plane:
Take the S7 (S-Bahn) to “Praterstern”. Change to the underground U2 to “Schottentor”. Go one level above to change for tram. See above for further instructions.See Wiener Linien for connections to “Schwarzspanierstrasse”.
