Abstract :
The ELETTRA light source will be filled by a linac only 60 m in length. A 100-MeV preinjector includes a subharmonic chopper and prebuncher, S-band prebuncher, 4-MeV buncher, and two accelerating sections. A FEL mode of operation will be possible. 200-MeV accelerating units follow. Each includes a 6.15-m 3 pi /4 backward traveling wave (BTW) section powered by a TH 2132 45-MW, 4.5- mu s klystron, compressed to 0.76 mu s by a Thomson CIDR (Compresseur d´impulsion a Double Resonateur) similar to the CERN design of the SLED. The main parameter choices represent a significant improvement on the RF linac state of the art in energy gain for a given length and power.<>
