ILC Damping Rings Workshop (ILCDR06)

26 Sept 2006, 08:00 → 28 Sept 2006, 13:00 Europe/Zurich

Cornell University's ILR Conference Center

This is the first in a series of workshops to prepare and implement R&D plans for the ILC Damping Rings. This meeting will focus on three primary areas of research: fast injection/extraction kickers, electron cloud in the positron damping ring, and impedance and impedance-driven instabilities.
