The Center for X-Rays in Swedish Material Science located in Sweden and the Swedish Material Science beam line situated at the PETRA III synchrotron in Germany together comprise the PETRA III Swedish Node – an ultra high energy beam line with two measurement stations specially designed for material science research experiments.
The background to the PETRA III Swedish Node was a Memorandum of Understanding between the Swedish and German governments to cooperate in infrastructure development and research . This understanding was mutually agreed in 2009 and in 2010 the Röntgen-Ångström Cluster (RÅC) established to implement this agreement.
When assessing how to implement this agreement, a key consideration for Sweden was ensuring complementarity to the MAX IV and ESS research infrastructures that were also being planned at that time [1, 2]. Such infrastructure complementary matched the measurement needs of material science researchers [1, 2].
The material science research community was actively engaged throughout this project , especially via a number of workshops:
- October 2010. "Swedish beamline kick-off" workshop. Stockholm.
- February 2011. Formal signing of the Memorandum of Understanding at Deutsches Elektronen Synchrotron (DESY), Hamburg - (DESY operate the PETRA III synchrotron).
- August 2011. "High energy material science" workshop. DESY, Hamburg, Germany.
- June 2012. Scientific workshop to review the Conceptual Design Report (CDR). Sigtuna.
- July 2013. Technical Design Report (TDR) workshop concerning a possible Swedish Material Science beamline at PETRA III.
Funding and construction
Sweden decided to finance the building and operation of a Swedish Material Science beamline at PETRA III, with The Swedish Research Council (VR) representing the Swedish government [3, 4].
Sweden also saw the importance of establishing a Swedish host for the future Swedish Material Science beamline at PETRA III. VR therefore made a call for a host university. KTH and LiU applied as the Center for X-Rays in Swedish Material Science consortium.
Construction of the hall where the Swedish Material Science beamline was proceeding and instrumentation began to be installed. Therefore, in November 2017, a workshop was held at DESY to raise awareness that the dreams of 2009 were becoming a reality for Swedish materials reseachers. The tangibility of this was then demonstrated in September 2018 when the first diffraction patterns were detected at the Swedish Material Science beamline.
In December 2018, Center for X-Rays in Swedish Material Science consortium was awarded the priviledge of hosting the Swedish Material Science beamline and given the responsibilities of safeguarding Swedish interests at PETRA III.
Rapid uptake in use of the Swedish beamline
The Swedish beamline become operational for Swedish researchers during 2019.
From 2019, Swedish researchers have privileged access to this Swedish material science beamline as well as privileged access to all beamlines at PETRA III that are operated by Deutsches Elektronen-Synchrotron (DESY) .
The Swedish Material Science beamline became the most sought after beamline at PETRA III by Swedish researchers in 2019 , a position sustained in 2020 .
In 2020, the PETRA III Swedish Node also became listed in The Swedish Research Council's inventory of research infrastructures that are of national interest to Sweden.
Measurements at the Swedish beamline are a key aspect of leading research, which is now begining to be published in high ranking journals.
