The
IWBS2004 program covered a number of different topics which were grouped into the following sessions:
FACILITY REPORTS: The facility reports on orbit stabilization highlight the achievements/plans at present and future light sources.
NOISE SOURCE SUPPRESSION: Proper specifications/modifications for/of various accelerator components allow the initial orbit motion without feedback to be minimized.
ORBIT MEASUREMENT/CORRECTION: The remaining orbit motion must be measured and corrected; in particular the movement of insertion devices can induce significant orbit noise which needs to be compensated by means of feed-forward and/or feedback schemes. ``Top-up'' operation guarantees a constant heat load on all accelerator and beam-line components and thus allows for high mechanical stability. Together with the utilization of fast orbit feedback systems, ``top-up'' operation makes it possible to achieve sub-micron stability on a scale from ms to days.
USER EXPERIENCE: Two beam-line scientists from the SLS kindly agreed to share their experience with the workshop participants. They offered insight into the orbit stability requirements for experiments at their beam-lines.
STABILITY REQUIREMENTS IN 4TH GENERATION LIGHT SOURCES: Position and energy stability requirements in linear accelerator (linac) based 4th generation light sources are demanding and require the use of slow and fast feedforward/feedback systems.
It was the organizer's deliberate intention to allow adequate time for discussions throughout the workshop. Coupled with the 38 excellent oral presentations of 20 min length (80 % of the participants gave talks) this inevitably led to a very tight schedule,
which additionally included excursions to the SLS and the Jungfraujoch as part of the social program.
