First light for pioneering SESAME light source

This is of particular significance since this is the first high-energy accelerator in the Middle East.

On the 22th November et 10:50 in the morning scientists at the pioneering SESAME light source saw First Monochromatic Light through the XAFS/XRF (X-ray absorption fine structure/X-ray fluorescence) spectroscopy beamline, signalling the start of the laboratory’s experimental programme. This beamline, SESAME’s first to come on stream, delivers X-ray light that will be used to carry out research in areas ranging from solid state physics to environmental science and archaeology.

“After years of preparation, it’s great to see light on target,” said XAFS/XRF beamline scientist Messaoud Harfouche. “We have a fantastic experimental programme ahead of us, starting with an experiment to investigate heavy metals contaminating soils in the region.”

The initial research programme will be carried out at two beamlines, the XAFS/XRF beamline and the I nfrared (IR) spectromicroscopy beamline that is scheduled to join the XAFS/XRF beamline this year. Both have specific characteristics that make them appropriate for various areas of research. A third beamline, in this case devoted to materials science, will come on stream in 2018.

Opening ceremony of SESAME

The SESAME light source was officially opened by His Majesty King Abdullah II on 16 May.

His Majesty was welcomed by the President of the SESAME Council, Sir Chris Llewellyn Smith, and the President Elect, Professor Rolf Heuer, both former Directors General of CERN, the Director, Professor Khaled Toukan, H.R.H. Princess Sumaya bint El Hassan, the Prime Minister of Jordan, H.E. Mr Hani Al-Mulki, and the Administrative Director, Professor Yasser Khalil.
The King unveiled a plaque marking the official opening of the laboratory and visited the experimental hall.

SESAME’s 800 MeV booster synchrotron is now in operation

This is of particular significance since this is the first high-energy accelerator in the Middle East.

After having successfully stored electrons from the 20 MeV Microtron in the Booster in July 2014, on 3 September 2014, the SESAME team succeeded in accelerating the electrons in the Booster to their final energy of 800 MeV.

The SESAME Injector consists of a 20 MeV Microtron and the 800 MeV Booster-Synchrotron. Electrons are produced in the Microtron where they are accelerated to 20 MeV (Million Electron Volt), and these electrons are then transferred to the Booster-Synchrotron.

SESAME’s Microtron became operational in 2012, installation of its Booster was completed in 2013, and storage in the Booster, in July 2014, of the electrons from the Microtron meant that they were then circulating several million of turns in the Booster at their initial energy of 20 MeV.
