An Event Service for the Propagation of Data
17-DEC-2004, 7 pages [PS] [PDF]
An event delivery mechanism based on the CORBA Event Service is described. Lowlevel hardware data are aggregated by event processing agents to produce complex events which supply summarized data to event channels for distribution to registered consumers, typically high-level software applications. The CORBA Notification Service, a recent extension to the Event Service, is also examined and potential enhancements to our event delivery system are identified.

Achieving Sub-micron Stability in Light Sources
EPAC04, Lucerne,, 12-JUL-2004, 5 pages [PS] [PDF] [HTML]
One of the major goals for present and future light sources is to achieve sub-micron orbit stability of the electron beam at the photon beam source points over a large frequency range. This puts tight constraints on the design of the various accelerator components including girders, magnets, power supplies and diagnostic hardware. Fast orbit feedback systems based on high performance RF- and X-BPMs become essential to suppress residual orbit distortions. Furthermore, the top-up operation mode which guarantees a constant electron beam current and thus a constant heat load in 3rd generation light sources is one of the key ingredients to reach sub-micron stability.
