NSLS-II Seminar

"Modeling study of SPEAR3 nonlinear dynamics"

Presented by Xiaobiao Huang, SLAC

Wednesday, July 20, 2011, 10:30 am — NSLS-II Seminar Room, Bldg. 817

Lattice modeling is studied to understand the nonlinear dynamics of the SPEAR3 ring, using data from magnet modeling, magnetic field measurements and alignment requirements. The gradient dipoles are modeled with an analytic magnetic field profile and a numeric integration pass method in Accelerator Toolbox (AT). Linear and nonlinear effects of quadrupole fringe field are included with a new AT pass method. Linear and nonlinear parameters from the modeling are compared to experimental measurements.
