The use of neutrons and photons in Earth sciences - A workshop report
On May 8 we held a full-day workshop at the Department of Earth Sciences at Uppsala University, on the application of neutrons and x-rays in Earth sciences. The motivation for the workshop was mainly that the use of these techniques remains underexploited at the department today and, considering current developments at the Swedish National Synchrotron Laboratory (MAX IV) and the upcoming European Spallation Source (ESS) the aim of the workshop was to increase our readiness and illustrate the capabilities of these facilities.
Thirty-three participants from national and international institutions attended the workshop, noting that the attendees consisted dominantly of PhD students and early career researchers. The workshop started with an introduction to the Centres for Neutron Scattering and Photon Science at Uppsala University, whose organizations helped sponsoring the workshop. Six speakers then provided presentations on the use of neutron scattering and photons on a diverse set of topics that spanned cloud formation in the atmosphere to the structure of iron in Earth’s innermost core.
Speakers and topics at the workshop:
Dr. Lawrence Anovitz – Application of neutron physics to enhanced understanding of geological systems
Dr. Stephen Hall – Investigating the mechanics and hydro-mechanics of geomaterials with x-rays and neutrons
Prof. Martin King – The oxidation of organic matter in the atmosphere: Studying reactions at air-water-mineral interfaces that may affect modern climate change
Dr. Zuzana Konopkova – European x-ray free-electron laser facility, Hamburg: Studying deep Planetary interiors using synchotron radiation and free electron laser techniques.
Prof. Ingmar Persson – What can MAX IV do for geo- and soil- sciences, and some examples of this
Dr. Guying Shen – Synchrotron x-rays: a key to probing Earth’s and planetary interiors
Participants that attended the workshop came from many different institutions:
Uppsala University (Sweden)
Swedish University of Agricultural Sciences (Sweden)
Carnegie Institution of Sciences (USA)
Royal Holloway University of London (United Kingdom)
Oakridge National Laboratory (USA)
European XFEL (Germany)
Research Institutes of Sweden (RISE)
Recent work at Uppsala University
Uppsala University has developed neutron absorbing components made with boron carbide/plastic composite. These can be 3-D printed to make a range of products. The technology developments, for example, described in the paper Anders Olsson, Maja S. Hellsing, Adrian R. Rennie 'New possibilities using additive manufacturing with materials that are difficult to process and with complex structures' Physica Scripta 92, (2017), 053002, are now exploited by a start-up company Additive Composite Uppsala AB established this year. A successful delivery of components has already been made to the European Spallation Source (ESS). For links see below the image.
Spinach used in neutron studies could unearth secret to stronger plant growth
"Marvin Seibert at Uppsala University is using neutrons to study RuBisCO, an abundant enzyme essential to life on earth. His team hopes to determine how plants and other organisms use RuBisCO to catalyze a reaction called carbon fixation that converts carbon dioxide into useful organic compounds."

The Swedish research minister, Helene Hellmark Knutsson visit to RAL
The Swedish Minister for Higher Education and Research, Helene Hellmark Knutsson, visited the neutron facility at Rutherford Appleton Laboratory on 19 March 2018. She had the opportunity to learn about some research projects being conducted with Uppsala University and to discuss with graduate students Shirin Nouhi and Emil Gustafsson as well Professor Adrian Rennie. She was particularly interested in the work related to environment and health that involved international collaborations.
The picture shows (left to right) Helene Hellmark Knutsson, Emil Gustafsson, Shirin Nouhi and the RAL scientist Max Skoda discussing a neutron reflection experiment.
Workshop in the use of Neutrons and Photons in Earth Sciences
The purpose of this workshop is to convey the research potential of neutrons (spallation sources) and photons (synchrotron radiation) to geoscientists at Uppsala University. This potential is largely underexploited at the department today and, considering current developments especially at the Swedish National Synchrotron Laboratory (MAX IV) and the upcoming European Spallation Source (ESS), we would like to increase our readiness, and illustrate the capabilities of these facilities. The target audience consists mainly in PhD students and researchers from the Department of Earth Sciences at Uppsala University (Geocentrum). We expect about 25 participants across fields of mineralogy & petrology, geophysics, paleo-biology, hydrology, meteorology, glaciology, and physical geography. If possibility arises we will expand the workshop to include participants in other departments at Uppsala University, and regionally.
The workshop is open for 25 participants, and feel free to register by contacting Bjarne Almqvist (firstname.lastname@example.org) or Peter Lazor (email@example.com), no later than April 20. There is no registration fee for the workshop, and lunch is included in the participation if you have previously registered.
GISANS at ESS

Workshop on GISANS, February 19-20, Germany
There will be a workshop on GISANS that takes place in Garching, Germany on 19 and 20 February, 2018. The workshop is sponsored by the Centre for Neutron Scattering. If you would like to know more please contact: Adrian Rennie, firstname.lastname@example.org.
SNSS support initiative to build instrumentation at ESS
Swedish researchers want to develop and build instruments at ESS, including the world-wide GISANS instrument - which can only be achieved thanks to access to the world's most powerful neutron source, ESS. According to the ESS Scientific Council, the design and financing of instruments at ESS is urgent. The Swedish Neutron Scattering Society (SNSS) therefore proposes that Swedish industry merge and finance instrument through foundation, PPP, investment fund or other capitalization in cooperation with government research financiers and foundations.
