The Karlsruhe Tritium Laboratory (TLK)

of the Institute for Astroparticle Physics (IAP)

The Institute for Astroparticle Physics (IAP) operates the European Tritium Laboratory Karlsruhe (TLK), a semi-technical scale facility for processing tritium, the radioactive hydrogen isotope. With its license to handle up to 40 grams of tritium, its present site inventory of about 30 grams of tritium, and its extensive infrastructure and experimental apparatus, TLK is almost unique - only Japan operates a research laboratory with a similar tritium inventory, however with a much smaller laboratory area.
TLK is a major facility of the German Helmholtz-Gemeinschaft research organisation.

More than 20 glove box systems, total volume of about 190 m³, are operated in an area of 1600 m² for experiments and infrastructure facilities. The TLK can look back on a history of more than 25 years of safe operation and experience with tritium.
