Improvement of the Current DELTA Lattice Model Based on Measured Response Matrices — •Andreas Glassl, Stephan Kötter, Thomas Weis, and Bernard Riemann — TU Dortmund University (DELTA) Center for Synchrotron Radiation

An improved lattice model for the electron storage ring DELTA at TU Dortmund is being investigated using MAD-X. For this purpose, an already existing lattice model is updated by introducing fringe fields and data related to new measurements of magnet positions e.g. The linear predictions of this model is compared to optical functions and tunes computed by the COBEA-algorithm (AKBP 66) using measured response matrices of the storage ring as input. To improve the lattice model further the consideration of nonlinear field moments created by sextupoles and modified quadrupoles is presently under progress. Recent results will be presented together with first suggestions for a lattice model aiming at reduced momentum compaction factors while keeping magnet positions and minimizing variations to magnet strengths.
