The LOTUS shielded cavity was designed for testing blanket materials for fusion technology by means of a 1012 s-1 D-T neutron generator. The generator has been dismantled, but the cavity remains and is used as an irradiation cavity by LRS for strong radioactive neutron and gamma sources. New experimental programs are currently under design, making use of a new beam irradiator equipped with a 370 GBq Co-60 source (SILC).
