HESEB - Helmholtz-SESAME Beamline in the soft X-ray regime

News and Events

Another event is planned for the fall of this year. More information will be published soon.

HESEB soft x-ray lecture & training course at SESAME on May 8-9, 2023

The program was extended over two full days at SESAME and comprised the following elements:

  • base lecture program in soft x-ray science, applications, techniques and related optics/instrumentation
  • practical training in sample preparation, vacuum techniques, etc.
  • hands-on training and participation in experimental activities at HESEB
  • opportunities for networking and new contacts with fellow researchers and international experts
  • learning how to write successful beam time proposals.


Participation in the hands-on training was limited to seven participants to provide a good and stimulating learning experience and enable addressing the specific needs and requests of the participants.

Research stay programme

The program is targeting researchers from a university or a research institution in a SESAME member country, i.e. in Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, Palestine or Turkey who would like to use soft X-rays from a synchrotron in their research, but feel that they were still lacking the necessary experience.

The program offers the following

  • Research stay of two months  at a soft X-ray beamline of one of the participating synchrotrons.
  • Integration into the beamline team and participation in their daily work including support of the on-site users
  • Learning by doing and possibility to discuss and to ask questions to team colleagues and to user groups
  • Ample opportunities to establish new contacts
  • Full coverage of the costs for travel and accommodation plus daily allowance

Current stage

The call for applications is closed and the evaluation of the applications has been completed. More than 80 very interesting and competitive applications were received for only 10 places and so unfortunately a selection had to be made. The criteria were the quality of the application, the suitability of the research field for an extensive use of soft x-rays with the particular parameters of HESEB and the muliplier potential of the applicant. In addition, we tried to keep a good balance between applicants from the various SESAME member countries.

All candidates have been informed about the outcome of the evaluation. Several successful candidates left already for their reserach stay.

SESAME Cultural Heritage Day on February 16, 2022

An online event to promote cultural heritage sciences at SESAME
Date: Wednesday, 16 February 2022

Time: 9am - 1:15pm EET / 8am - 12:15pm CET

Synchrotron radiation sources and their vast characterization techniques have already made profound impacts on the study of cultural heritage. This includes the non-destructive investigations of archaeological / historical objects, artworks and artefacts, human remains as well as corrosion and deterioration processes at objects to better understand conservation and restoration efforts.    

The synchrotron radiation facility SESAME offers scientific access in a region that is known for its richness in archaeological and cultural heritage. Many highly-esteemed museums, collections, research institutions and universities in the region have departments dedicated to the scientific and art historical research into their heritage. With the existing and soon to be upgraded beamline portfolio at SESAME a highly useful and versatile research tool of highest analytical finesse for researchers, conservators, and cultural heritage specialists in the area is available which has widest applicability across the domains of archaeology and cultural heritage.

HESEB colloquium on December 15, 2020

The last HESEB lecture within the frame of the HESEB colloquium took place as an online event.

The lecture was be given by Dr. Florian Kronast from the Helmholtz-Zentrum Berlin für Materialien und Energie.

The title of the lecture is "XPEEM: Magnetic Imaging and Spectroscopy at the Nanoscale".

Due to the ongoing pandemics we will be obliged to have an online meeting.
Please register via the following link, if you are interested in this meeting: https://forms.gle/u4CMxH1HUybHe5566
The link to the meeting will be provided to the registered participants shortly before the event.


Here you can find some of the lectures which were presented online on October 20th:

The history of SESAME

The research centre SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East, www.sesame.org.jo) near Amman/Jordan was officially founded in 2004 as an international research project under the auspices of UNESCO with multilateral cooperation of countries of the Middle East region (Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, Palestine, Turkey). It was the idea and tireless commitment of Herman Winick (SLAC), Gustav-Adolf Voss (DESY) and Herwig Schopper (CERN) which eventually lead to the foundation and build-up of a research facility in the Middle East – with the vision that close scientific cooperation would make a contribution to peace and stability in this region.

Scope of the project

The five Helmholtz centres DESY, FZJ, HZB, HZDR and KITjoined forces to build at SESAME a new and state-of-the-art Helmholtz-SESAME soft X-ray beamline (HESEB) in the soft X-ray range to be used for a large number of top-class scientific applications and to create new cooperation potentials with German and international research groups. Corresponding training, education and support measures offered by the participating Helmholtz centres shall guarantee the international scientific attractiveness and quality of the beamline as well as secure its long-term scientific use and excellence by creating and supporting scientific user communities within the region and by building up and connecting long-lasting cooperation among the SESAME members and with other user groups worldwide.

User support, cooperation development, Seed Projects / Teaming

To secure a large and sustainable request for scientific use of the soft X-rays from the Helmholtz SESAME beamline, dedicated workshops and schools are being offered in order to build up a strong user community in the SESAME region in the medium and long term. In addition, grants for several months of training or research stays of future SESAME users at adequate synchrotron radiation sources and research centres in Germany will be offered.
