DESIR (Desintégration, excitation et stockage des ions radioactifs, i.e. decay, excitation and storage of radioactive ions) will form the experimental area exploiting low-energy beams of the next-generation radioactive beam facility SPIRAL2 at GANIL, presently under construction. In addition to beams from the SPIRAL2 production building, DESIR will also receive beams from the separator-spectrometer S3 and from the SPIRAL1 facility. In the following, the DESIR facility and its instrumentation related to Penning trap based mass spectrometry and trap-assisted decay spectroscopy are introduced. The related envisaged experimental program is outlined.
