SESAME (synchrotron)

from Wikipedia, the free encyclopedia

The Synchrotron-light for Experimental Science and Applications in the Middle East ( SESAME ) is a synchrotron in Allan in the Governorate of al-Balqa in Jordan , which was built with parts of the decommissioned BESSY storage ring . It is the first synchrotron in the Middle East and opened on May 16, 2017.

The SESAME project was initiated at the end of the 1990s when it was clear that the German storage ring BESSY I should be dismantled in 1999. Under the auspices of UNESCO , several countries from the Middle East and Mediterranean region came together to continue operating the storage ring after a technical upgrade (2.5 GeV energy, 133 m circumference). In 2000, Jordan was chosen as the location, and in 2002 BESSY I was shipped there. The building was inaugurated on November 3, 2008. On July 14, 2009, an electron beam was generated with the microtron for the first time . The microtron is the last acceleration stage before the electrons are injected into the actual synchrotron. Regular operation of the plant began in 2017. Participating countries are Egypt, Bahrain, Iran, Israel, Jordan, Pakistan, the Palestinian Territories, Turkey and Cyprus. Monochromatic X-rays were observed for the first time on November 22, 2017.
