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.

TITLE: Performance and Developments of NSLS-II BPMs
SPEAKER: Weixing Cheng, BNL
ABSTRACT: NSLS-II in-house developed BPM systems provide better than 200nm resolution and sub-micron long-term position stability, combined with the high-temperature stability of the storage ring tunnel, electronic racks, sophisticated support structures and orbit feedback. The talk will start with the introduction of the NSLS-II BPM button and electronics design, followed with measured performances of the system, including short and long-term orbit stabilities. Recent developments based on the BPM electronics enhance the capability for advanced beam measurements, as well as the stable operation of the low emittance storage ring. Examples of such developments, like the BPM gated function, fast glitch detection and beam measurement results will be presented. Future developments like pilot tone calibration and a newer version of electronics will be discussed to continuously improve the stable/reliable operations and beam studies at NSLS-II.
