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: The NSLS-II Low Level RF System: Operations and Beam Studies
SPEAKER: Jim Rose, Brookhaven National Laboratory
ABSTRACT: Using a common hardware platform for booster, storage ring and MO distribution the NSLS-II digital LLRF controller is a versatile platform for RF field control in synchrotrons. Using modular FPGA code and conditional compilation the instantiation of feedback, ramp generators and interlock components are conditional depending on the needs of the RF system targeted. A wide range of applications within logic such as a 7 channel Network Analyzer, constant-phase amplitude limiter, quench detection and feedforward tables have been in operation for several years and will be described. Accelerator study results including RF-Beam transfer function measurements will be presented as well as performance studies at the Canadian Light Source and NSRRC’s TLS and TPS.
