NSLS-II Friday Lunchtime Seminar

"Results to date on the elimination of Insertion Device Motion control problems by the NSLS-II Insertion device working group"

Presented by John Escallier, NSLS-II

Friday, March 15, 2019, 12:00 pm — NSLS-II Bldg. 744 Room 156

Control of Insertion Device gap motion by the use of the Delta Tau control platform requires a good understanding of several disciplines simultaneously. Physics, magnetics, mechanics, electronics, software, and control theory are all specialties needed to establish full control of the gaps. The ID working group is comprised of individuals who specialize in one or more of these disciplines, and have been quite successful at attacking and solving multiple issues related to the IVU devices. Improvements in accuracy and control have exceeded close to two orders of magnitude, while simultaneously keeping focus towards the eventual use of step and fly scanning of the gap in synchronous motion with other devices. As work on the first vendor's devices begins to ramp to completion, the group effort is being directed towards work on EPU's. This seminar will detail several of the problems encountered, how they were solved, and where the future lies.
