The Synchrotron-Light for Experimental Science and Applications in the Middle East (SESAME) is an independent laboratory located in Allan in the Balqa governorate of Jordan, created under the auspices of UNESCO on 30 May 2002. Aimed at promoting peace between Middle Eastern countries, Jordan was chosen as the location for the laboratory, as it was then the only country that maintained diplomatic relations with all the other founding members; Bahrain, Cyprus, Egypt, Iran, Israel, Pakistan, the Palestinian Authority, and Turkey. The idea, to create a joint Arab-Israeli scientific collaboration, goes back to the 1980s and took a more concrete form in discussions at CERN in 1993. The project was launched in 1999 and the ground breaking ceremony was held on 6 January 2003. Construction work began the following July, and the facility was finally inaugurated on 16 May 2017 under the patronage and presence of King Abdullah II. The construction of the project cost around $98 million, with $5 million donated each by Jordan, Israel, Turkey, Iran, and the European Union. The rest was donated by CERN from existing equipment. Jordan became the greatest contributor to the project by donating land and building construction costs, and by pledging to build a $7 million solar power plant, which will make SESAME the first accelerator in the world to be powered by renewable energy. The annual operational cost of $6 million are pledged by the members according to the size of their economies. The facility is the only synchrotron radiation facility in the Middle East and is one of around 60 in the world. As of May 2017, the president of the SESAME Council is Rolf Heuer. He was preceded by Christopher Llewellyn Smith (2008-2017) and Herwig Schopper (2004-2008). All three were previously directors-general of CERN. Khaled Toukan, the chairman of the Jordan Atomic Energy Commission, is the current director and former vice-president of SESAME.
Background Synchrotron light (also referred to as synchrotron radiation) is radiation that is emitted when charged particles moving at speeds near the speed of light are forced to change direction by a magnetic field. It is the brightest artificial source of X-rays, allowing for the detailed study of molecular structures. When synchrotrons were first developed, their primary purpose was to accelerate particles for the study of the nucleus. Today, there are almost 60 synchrotron light sources around the world dedicated to exploiting the special qualities, which allow it to be used across a wide range of applications, from condensed matter physics to structural biology, environmental science and cultural heritage.
History
The need for a large-scale scientific project to bring the Middle-East back into the scientific community as well as promote peace and foster international collaboration has been recognised for almost 40 years. In his speech at the 1979 Nobel Prize banquet, Pakistani physicist Mohammad Abdus Salam stated that we should "strive to provide equal opportunities to all so that they can engage in the creation of Physics and science for the benefit of all mankind". In his paper presented at the Symposium on the "Future Outlook of the Arabian Gulf University", on 11 May 1983, in Bahrain, titled The Gulf University and Science in the Arab-Islamic Commonwealth, Abdus Salam proposed the founding of a Super Gulf University and an international laboratory in material sciences in Bahrain. Such a laboratory was proposed for the University of Jeddah, to emphasise science and technology transfer in the material sciences, including a laboratory with a synchrotron radiation light source. Ultimately, the proposal did not come through, possibly because it had the sponsorship of a single university rather than a consortium of universities. In 1997, Herman Winick and Gustav-Adolf Voss suggested building a light source in the Middle-East using components from the soon-to-be decommissioned BESSY I facility in Berlin, during two seminars organized in 1997 in Italy and in 1998 in Sweden by Tord Ekelöf with the CERN-based Middle East Scientific Co-operation (MESC) group headed by Sergio Fubini. Winick was credited with the idea of moving the machine to the Middle-East during discussions about the future of the machine. He explained "(his) main motivation is to help create a project in which people can work constructively and collectively." This proposal was adopted and pursued by MESC. The German government agreed to donate the necessary equipment at the request of Fubini and Herwig Schopper. Believing that the only chance of realizing such a project was following the example of CERN, the plan was brought to the attention of Federico Mayor, then Director-General of UNESCO, who organized the Consultative Meeting on a Middle East Synchrotron Light Facility, at UNESCO headquarters in Paris in June 1999. The meeting resulted in the launching of the project and the establishment of an International Interim Council under the chairmanship of Herwig Schopper. In May 2002, the executive board and Director General of UNESCO unanimously approved the establishment of the Centre under UNESCO auspices, through resolution 31C/Resolution 19. The groundbreaking ceremony for SESAME took place at Al-Balqa' Applied University in Jordan, on 6 January 2003. SESAME used offices at the UNESCO Office in Amman until the completion of the building in 2008. In April 2004, the centre formally came into existence when the required number of Members had informed UNESCO of their decision to join. and a permanent Council was established. The founding members were Bahrain, Egypt, Israel, Jordan, Pakistan, and Turkey. The current Members are Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, the Palestinian Authority, and Turkey. The Observers are Brazil, Canada, China, the European Union, France, Germany, Greece, Italy, Japan, Kuwait, Portugal, Russia, Spain, Switzerland, Sweden, the United Kingdom, and the United States. SESAME was officially opened on 16 May 2017 by King Abdullah II of Jordan.
