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

The means have become available to built up SESAME now! Iran,
Israel, Jordan, Turkey will contribute 5 M$ within next four years.
Pakistan might contribute in kind. CERN/EU contribute 5 M for the
purchasing of the magnet system. Italy will contribute 1 M .

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. Bodrum,

Accelerated electrons emit Electromagnetic Waves Electrons in a
dipole move like the ones in an antenna. The antenna is moved (by
speed of light). The waves are compressed in forward direction. The
radiation becomes harder : microwave, light, x-rays. The radiation
is peaked in forward direction. What is Synchrotron Radiation?
