TSL - The Svedberg Laboratory

The TSL is a university facility, based in Uppsala, Sweden.

Gustaf Werner cyclotron

The Gustaf Werner cyclotron at TSL provides particle beams for:

Proton patient

Proton therapy: The main activity of TSL is based on an agreement between Uppsala Academic Hospital and Uppsala University about proton therapy, read more about proton therapy at TSL.


Radiation testing: Beamtime not used for proton therapy will be devoted to commercial neutron and proton irradiation projects. Read more about our irradiation facilities.

Basic Research

Basic research: There will still be some time for basic (academic) research and in this case the experiments should be associated to Uppsala University or to EU projects. Read more about basic (academic) research at TSL.

Notice board

A new irradiation position, CUP (Close User Position) has been constructed, characterized, and put into operation at the ANITA facility for accelerated testing of components and systems for single event effects. The energy-integrated neutron flux above 10 MeV, amounting to more than 107 cm-2 · s-1, is the highest among the facilities with atmospheric-like spectra. Results of beam characterization measurements are reported in the recent publication:

A.V. Prokofiev, E. Passoth, A. Hjalmarsson and M. Majerle, ”CUP – A New High-Flux Irradiation Position at the ANITA Neutron Facility at TSL”, IEEE Transactions on Nuclear Science, Vol. 61, pp 1929-1936 (2014).

ANITA-CUP, new user position with extra high neutron flux

During 2013 a new irradiation position was constructed, characterized, and put into operation at the ANITA facility for accelerated neutron SER testing. The neutron flux, ≈107 cm-2s-1, is the highest among facilities with atmospheric-like spectrum. See the poster about ANITA-CUP that was presented on RADECS2013 (Oxford, UK, 23-27 Sep 2013) and on the Workshop on fast neutron applications at spallation sources (Abingdon, UK 30 Sep - 1 Oct 2013).


Curiosity´s radiation instrument calibrated at TSL

Curiosity RAD detector

Since August 2012 the space rover Curiosity has been exploring Mars surface. Did you know that the rover´s instrument for measuring radiation was calibrated at TSL?

Read more about it in this Uppsala University article.

RAD graphs

See graphs of radiation levels on the RAD site.

More about Curiosity can be found on NASA´s site about Mars Science Laboratory.
