AbstractAbstract
[en] The Compton backscattering experiment is put forward to produce hard X rays of high-brightness and polarization for making up the shortcoming of no hard X-ray source in NSRL, and the hard X rays wavelength will be adjusted continually by tune the wavelength of FEL. The parameters of the FIRFEL and the project of the compton backscattering experiment are present for the storage ring of NSRL, and the theoretical results are given also

AbstractAbstract
[en] The spontaneous emission of TOK in Hefei storage ring was simulated with Monte Carlo method. Section one described the structure of the permanent magnet TOK and the magnet field of TOK. Section two simulated results, and simulated results illustrated how the energy spread and emittance of electron beam impose on the spectrum of spontaneous emission. And with help of simulated results, the causes of small modulation factor which was measured by experiment was discussed

AbstractAbstract
[en] The differential relation between optic parameter and lattice parameter in electron storage ring of HLS is presented; the lattice parameter at down river is evaluated and analyzed when the optic parameter at upriver is changed. Using the expression the lattice parameters is calculated when the Wiggler is inserted, satisfying the need of the improvement of NSRL (National Synchrotron Radiation Lab.). Considering this relation, the lattice is designed renewedly in order to reduce the β function where the Wiggler is inserted

AbstractAbstract
[en] The effects of the optical klystron on the beam (such as emittance, energy spread, damping, closed orbit, the vertical tune, and the distortions of the vertical focus) are discussed. We present a compensated method of the distortion of Twists parameters

AbstractAbstract
[en] The orbit functions for HLS storage ring have been studied using the simulation code MAD. The effects of alignment errors of the quadrupole, dipole magnets were simulated. The effects of these errors on the orbit distortion and coupling are then graphically analyzed to show the rms spread of the functions. The studies show that the most significant closed orbit distortion was caused by displacement of the quadrupole magnets, and the amplification factors are presented, while providing the opportunity of future upgrade in alignment. In addition, the coupling between the horizontal and vertical emittance is analyzed, and the main coupling is due to the orbit distortion

AbstractAbstract
[en] A coherent harmonic generation FEL experiment is under way in 800 MeV electron storage ring in National Synchrotron Radiation Laboratory, USTC. Spontaneous emission spectrum of a optical klystron for the experiment has been measured, a modulation factor of 0.7 has been obtained. The authors presents measurements of spontaneous emission spectrum and enhancement of modulation factor
