The Evolution of SESAME 1990s: A scientific cooperation as a vehicle of peace in the Middle East been proposed;I n particular, Middle East Scientific Cooperation (MESC) group, based at CERN (Sergio Fubini, Eliezer Rabinovici, Herwig Schopper, Tord Ekelof) 1997: Original idea (Voss, Winick); Upgrade/rebuild BESSY 1(0.8 GeV) in the Middle East, as centerpice for a new international research center. Voss presents the concept to a MESC meeting in Turino. 1999: 1st meeting at UNESCO; (Interim) Council established Herwig Schopper, President. 2002 - Decision to build a new 2.5 GeV ring (still using BESSY injector) 2003 - Ground breaking for building; completion in 2008 2008 Chris Llewellyn-Smith takes over as Council President Bodrum, UPHUK-5, Sep..2013, Erhard Huttel 3

Dynamic Aperture Electron beam size about 1x0.1 mm 2 Some Electrons are scattered into cm range. Might not get focused again and get lost. Dynamic Aperture gives space, they are captured again. Tune (h x, h y) : Scattered electrons oscillate with h x, h y cycles per revolution. If h x, h y has certain values, oscillations are not damped. Particles can get lost.
