Description
Hefei Light Source (HLS) is a dedicated synchrotron light source with an electron beam energy of 800 MeV. Due to the limited circumference of 66.13 m, the current lattice adopts Double-Bend Achromat (DBA) with 4 super periods. The natural emittance is 38 nm⋅rad . To improve the light source performance, we reselect the work point, based on the new work point, we optimize the beam nonlinear dynamic, including dynamic
aperture(DA),momentum aperutre(MA), which strongly connect beam lifetime and injection efficiency.The optimization only changes the strength of quadrupoles and sextupoles, while remaining the same drift length and magnet length, after the optimization, we have produced lattice with larger dynamic aperture and momentum aperture for new working point with positive chromaticities. The detail optimization is reported in this paper.
