NSLS-II Seminar

"Implementation and evolution of the top-up operation and filling pattern controls at the Swiss Light Source"

Presented by Timo Korhonen, Swiss Light Source, Switzerland

Wednesday, July 9, 2008, 2:00 pm — Seminar Room, Bldg. 725

The Swiss Light Source has been operated in top-up mode for practically its whole life time. The talk explains the necessary features of the timing and control system to achieve this. The operating modes and associated applications are outlined.
The applications have evolved from a simple open-loop filling to a sophisticated system that can handle different operating conditions and filling modes with a great degree of automation. During this evolution we have encountered a number of phenomena that we did not expect. Those phenomena are outlined and their causes and implications to for example beam stability are discussed.
The latest addition to the system is the recently upgraded filling pattern feedback system. The technical implementation and the main advantages of this system are explained.
