The users of SESAME will be scientists, including graduate students, mostly based in universities and research institutes in the Middle East and neighbouring region - profiles of some potential users may be found in the SESAME People Brochure. It is expected that they will typically visit the laboratory for a week or two, two or three times a year, to carry out experiments on the beamline that corresponds to the needs of their work, often in collaboration with scientists from other centers/countries, where they will be exposed to the highest scientific standards in a stimulating environment for international collaboration, and then return home to analyze the data they have obtained. These scientists bring back scientific expertise and knowledge, which they share with their colleagues and students at home.
SESAME's well-equipped beamlines, experimental end stations, laboratories, and other support facilities will be available to users, and a highly-trained scientific, technical and administrative staff will ensure that both experienced and inexperienced users of the Centre are successful in their experiments.
For scientists from Members of SESAME working in relevant areas of research and training, access to the SESAME science facilities, including existing beamlines and instruments, will be free of charge. For scientists from non-Members (including Observers), access to the SESAME science facilities will be subject to payment (whether financial, in-kind or manpower) to cover the needs of their experiments, and provide an indirect contribution to the Centre's general operating costs.
The SESAME Users' Executive Committee will represent the interests of users.
Several hundred scientists, working in disciplines ranging from the biological and medical sciences to archaeology, are expected to use SESAME from "Day One". This will make SESAME a unique multidisciplinary centre in the region. As more beamlines are built, the number of users is expected to grow to 1000 or more.
The potential user community in the region, which in 2011 already numbered some 200, has been fostered by a variety of training opportunities and events (users' meetings, schools and workshops) which have been supported by a range of national and international organizations.
