Design of a national dedicated synchrotron radiation facility
Design of a national dedicated synchrotron radiation facility The design of two electron storage rings intended exclusively for research with synchrotron radiation is described. The injection system, consisting of a 50 MeV linac and a 700-MeV separate function, FODO-type booster synchrotron, feeds both storage rings. The lattice of both storage rings consists of a series of achromatic bends connected by straight sections. With such an arrangement the electron emittance is minimized because the momentum dispersion function remains small in the bending magnets. An operating frequency of approximately 50 MHz was chosen for the rings corresponding to harmonic numbers 23, 7 and 6 in the x-ray ring, the VUV ring and the booster synchrotron. At this frequency, power amplifiers are readily available which operate efficiently and have long lifetimes. The vacuum system, shielding, experimental facilities, and the building are discussed, and a cost estimate and project schedule are given.
