TSL - The Svedberg Laboratory

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

Today there are no experiments or irradiation project running at TSL. Uppsala University has decided to decommision the accelerator plant or transfer it to some other institute or company. The old organisation TSL has been replaced with a new, smaller organisation IFA-TSL, hosted under IFA, UU. The particle accelerator and the irradiation facilities are still in running conditions and will stay so during whole 2017!

The particle accelerator Gustaf Werner cyclotron at TSL provided up to June 2016 particle beams for:
