STATUS OF THE ELSA-2 PROJECT

The ELSA facility (1) was designed in the 80's as a test bench for high-power FEL physics and technology. It is now mainly used as a high brightness 1-20 MeV electron source or as a picosecond hard X-ray source. In response to this change in the user's needs, dedicated beamlines are under construction in a new experimental area. The main features of the project will be reviewed: the linac energy upgrade up to 40 MeV, a new design for the magnetic buncher using two alpha magnets (with a unit field index), and plans for a Thomson source. This source in the 1-50 keV range will use the intrinsically synchronous drive laser of the photoinjector.
