Free-electron lasers and high-energy physics accelerators have increased the demand forvery high-brightness beam sources. This paper describes the design of an accelerator which has produced beams of 2.1πmm-mradat 1 nC and emittances of 3.7 and 63πmm-mrad for 2 and 3 nC, respectively. The accelerator has been operated between 10 and 18 MeV. The beam emittance growth in the accelerator is minimized by using a photoinjector electron source integrated into the design ofthe linac, a focusing solenoid to correct the emittance growth caused by space charge, and a special design of the coupling slots between accelerator cavities to minimize quadrupole effects. The FEL has recently operated at 5microns.
