Design of the e/sup +e/sup -/ Frascati linear accelerator for DA/spl Phi/NE

The electron-positron accelerator for the DA/spl Phi/NE project is under construction at Titan Beta in Dublin, CA. This S-band RF linac system utilizes four 45 MW sledded klystrons and 16 3 m accelerating structures to achieve the required performance. It delivers a 4 ampere electron beam to the positron converter and accelerates the resulting positrons to 550 MeV. The converter design uses a 4.3 T pulsed tapered flux compressor along with a pseudo-adiabatic tapered field to a 5 KG solenoid over the first two positron accelerating sections. Quadrupole focusing is used after 100 MeV. The system performance is given. This paper briefly describes the design and development of the various subassemblies in this system.< >
