| Abstract: | 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. |
