ASD Seminar Series

The goal of this seminar is to encourage interaction between groups, act as an open forum to share ideas, achievements, and results, promote collaboration, communicate what APS personnel are doing and to educate people. Talks can be projects, tasks, ideas, etc. that are new, unfinished, ongoing as well as fully developed. This seminar is very informal and does not require a fully formatted presentation.

To suggest a speaker or to volunteer, please contact Geoff Waldschmidt

Next Seminar:  Wednesday, July 12, 2017 @ 11:00 am, Conf. Rm. A1100

TITLE: Cross-Talk Simulation between Q2 and L-bend Magnets for APS-U

SPEAKER:  Melike Abliz, PSC

ABSTRACT:  This talk describes the modeling results of Q2 and L-bend magnets and evaluates the cross-talk between them. Downstream of Q2, the strong field side of the L-bend magnet will be located in the lattice of the APS-U. These magnets are separated by only 50 mm, with an angle of 0.894° with respect to each other in the 67 pm lattice. Minimizing their cross-talk is a key issue in achieving the required beam trajectory from the upstream end of the Q2 to the downstream end of the L-bend. Therefore, modeling their interaction is essential to confirm the designed fields along the beam trajectory. 
The required integrated quadrupole, dipole, and multipole fields of these magnets were computed individually as a baseline for the cross-talk studies. The integrated cross-talk simulations were then evaluated to determine if the designs of these magnets were acceptable, and whether magnetic measurement data of the individual magnets was still applicable during installation in the ring.
