1 Bölgemizdeki Sinkrotron IşıI şınımı Projeleri SESAME (Ürd( rdün) ve CANDLE (Ermenistan) 1

2 Bölgemizdeki SR Projeleri SESAME (Ürdün) Synchrotron-light for Experimental Science and Applications in the Middle East 2

3 Sinkrotron IşıI şınımı There are now about 60 operating synchrotron sources around the world, 10 in construction and 13 proposed; 23 countries are involved. The worldwide user community for synchrotron radiation is estimated to be in excess of 20,000. Even taking in to account the new sources under development, the rapid growth of the user community and ever increasing range of applications outpace the available supply of synchrotron light for the foreseeable future. In a synchrotron bunches of charged particles - electrons - circulate at nearly the speed of light for several hours inside a ring-shaped, long tube under vacuum. As magnets in the ring force the electrons to bend they emit "synchrotron light" whose wavelength can range from infrared radiation to x-rays. x The emitted light is collected by many different "beamlines" beamlines" (optical systems) connected Prof.Dr.Ömer to the Yavas ring, and thus many experiments can be run simultaneously. 3
