Research perspectives at Jefferson Lab: 12 GeV and beyond

The plans for upgrading the CEBAF accelerator at Jefferson Lab to 12 GeV are presented. The research program supporting that upgrade is illustrated with a few selected examples. The instrumentation under design to carry out that research program is discussed. Finally, a conceptual design of a future upgrade which combines an electron-ion collider facility at a luminosity of up to 1035 cm-2s-1 and a CM energy of up to 65 GeV with a 25 GeV fixed-target facility
