Collaboration between MAX IV and the Department of Energy

MAX IV has an ongoing project to strengthen collaboration with the American synchrotron light sources. The project runs from 2024 to 2026 and is funded with just over 2.4 million SEK from the Swedish Research Council.

The focus is on researchers and technical personnel in Sweden and the USA to collaborate to develop methods and instrumentation that make it possible to take full advantage of the greatly improved possibilities to produce a high-intensity and coherent X-ray beam generated at fourth-generation synchrotrons. MAX IV, which was inaugurated in 2016, initiated the development of fourth-generation synchrotrons and now several new or upgraded facilities with similar performance are being commissioned around the world.

The US Department of Energy (DOE) operates several synchrotron light sources: NSLS-II at Brookhaven National Laboratory, SSRL at SLAC National Accelerator Laboratory, ALS at Lawrence Berkeley National Laboratory and APS at Argonne National Laboratory. After an ambitious upgrade program, APS has successfully generated its first X-rays and joined the club of fourth-generation light sources. ALS is on track to achieve a similar upgrade by 2027.

The project provides the opportunity to identify and discuss potential collaborations, organize workshops and thematic meetings, develop action plans, and support travel for skills development and exchange from both parties. In principle, all user groups at MAX IV will benefit from the developments taking place within the project.

The project is also a continuation of a highly appreciated previous collaboration project that culminated in a workshop “Science Opportunities with Diffraction Limited Soft X-rays” held in April 2023, in Port Jefferson, New York. The workshop brought together 35 invited experts, nine of whom were from Sweden, and provided an ideal platform to discuss the capabilities of soft coherent X-rays.

The areas that are first in the new project are:

X-ray detectors - the X-ray radiation at a fourth-generation synchrotron light source offers completely new opportunities to develop techniques for investigating and imaging matter. However, the optimized detectors required for this are lacking in some cases, which limits researchers from fully exploiting these opportunities. This is especially the case with imaging detectors in the soft X-ray range. MAX IV has an ongoing collaboration with LBNL on a soft X-ray imaging detector that is currently being tested on a beamline at MAX IV. In the longer term, efforts are underway, particularly at BNL, to develop Low-Gain Avalanche Detectors (LGAD) that promise to deliver soft X-ray detectors with unmatched performance, which would also be of great interest to MAX IV.

Coherence Techniques - MAX IV together with NSLS-II plan to follow up the 2023 soft X-ray workshop by hosting a new workshop in the fall of 2025, to continue the collaboration and discussion on the possibilities of coherent soft X-rays. The new workshop is intended to focus primarily on OAM (Orbital Angular Momentum), a relatively unexplored but potentially very interesting property of coherent X-ray light and thus particularly interesting for long-term collaboration between the facilities.

Accelerator Techniques - The collaboration between the accelerator divisions at MAX IV and the DOE-funded facilities has always been extensive. Discussions are now taking place primarily between NSLS-II and MAX IV to develop advanced tools for the design, commissioning, and operation of low-emissivity storage rings. The exact collaborations that will be prioritized in this area have not yet been decided, but could include

  • using AI for design and optimization,
  • developing tools to automate deployment,
  • neural networks to better predict trends and failures in accelerator operation.

In addition to these three areas, there are also excellent opportunities for fruitful knowledge exchange and development of practices in areas such as X-ray optics, as well as data analysis and visualization.

The Swedish Research Council finances feasibility studies for future instruments at ESS


One of the areas that the Swedish Research Council has identified as important for Sweden concerning ESS is opportunities for Swedish researchers to participate in a competitive proposal for new instruments.

In recent years, two initiatives, in particular, have excelled. One is SAGA, a GISANS instrument (grazing-incidence small-angle neutron scattering) for structural studies of surfaces, thin films and boundary layers. Such experiments are of interest to both industry and academia in characterising all kinds of complex systems such as food and biological materials. The second is HIBEAM (high-intensity baryon extraction and measurement), an instrument for subatomic physics for studies of the fundamental properties of the neutron, which will be used to look for new physics beyond the so-called standard model.

Following the results of the needs inventory 2020, the Council for Research Infrastructures (RFI) decided to handle the instrumentation at ESS in a particular order, i.e. outside RFI's ordinary application procedures that were deemed not appropriate. As a step in this handling, RFI decided before the summer of 2021 to set up a targeted call for feasibility studies for future instruments at ESS. The SAGA and HIBEAM collaborations were invited to apply.

The applications have been prepared during the autumn. At its council meeting on 27-28 October, RFI decided to finance the SAGA and HIBEAM collaborations with SEK 10 million each during 2021-2023 to carry out the instrument feasibility studies. The feasibility studies will result in competitive proposals that can be submitted to the ESS council when the time is right to appoint the instruments that will constitute the ESS's future instruments.

The future for synchrotron light user organizations is bright

The question of the current role of the user organizations and their ability to increase the value for Swedish researchers was central when representatives of the synchrotron light organizations met in October 2023. The conversation partly highlighted the lack of contact between these organizations and the users today, especially the researchers who have not yet discovered the benefits of to use MAX IV as a tool in their research. The discussion on MAX IV's role focused on the need for facilities such as MAX IV to act to facilitate communication between user organizations and researchers.

  • For us at MAX IV, a broadened Swedish use of our radiation tubes is important, says Olof Karis, director at MAX IV. Sweden has invested in a world-leading research facility and the more researchers from academia and industry who use our techniques, the better. We look forward to a clearer connection between the user organizations and MAX IV, it is needed to increase communication with the researchers.

Several of the participants in the meeting believed that a national user organization should act as a channel to represent the needs of the user community vis-à-vis both facilities and funders.

Participants also discussed the lack of content on the FASM and SSUO websites. In order to increase commitment and clarity in the user organizations, a more explicit division of tasks between the organizations and clearer communication with the users was proposed. To optimize the flow of information, measures such as sending newsletters and using conferences and meetings to reach users were suggested. It was also discussed to use the DUO system for member recruitment and to create clear incentives for membership.

The discussion concluded that clearer structures and more active communication are needed to strengthen the user organizations and increase their influence. To increase awareness of the user organizations, a follow-up via e-mail was proposed to involve more participants and gather volunteers for board positions, mainly in SSUO. Interest in reviving the SSUO was discussed and there was clear support for doing so.

  • We have done extensive and successful work to probe the interest in an expanded board in SSUO, says Derek Logan, chairman of SSUO's board. On January 15, 2024, at FASM's and SSUO's annual meeting at MAX IV's user meeting, a new board was elected with representation from Lund University, Stockholm University, Uppsala University and Linköping University, and now we look forward to restarting operations.

SNSS (Swedish Neutron Scattering Society) is also looking forward to a close collaboration with FASM and SSUO.

  • MAX IV and ESS will offer unique opportunities for science in the coming years. A coherent strategy for neutron and synchrotron research and close cooperation between the user organizations will make it possible for Swedish society to make the best use of these unique infrastructures, says Max Wolff, chairman of SNSS.

Background

The Swedish Research Council, the Association for Users of Synchrotron Light at MAX IV (FASM) and The Swedish Synchroton Users Organization (SSUO) invited on 27 October 2023 to a digital roundtable discussion on how the Swedish organizations for users of synchrotron light facilities can be optimized. During the conversation, in which about 20 invited researchers from the country's universities participated, the future X-ray user organizations in Sweden and important questions regarding the user organizations' role, their current achievements and how MAX IV can cooperate with them to optimize the information flow and support Swedish researchers were discussed.

LoI for Swedish in-kind contribution to ESS 2021


The Council for Research Infrastructures (RFI) decided at its council meeting in September 2021 to add SEK 30 million per year during 2021-2025 for the initial operational phase at ESS and that the money preferably should be used for Swedish in-kind grants.

As possible in-kind for Sweden already in 2021, ESS and the Swedish Research Council have identified the ongoing accelerator testing activity at the FREIA laboratory External link. at Uppsala University as most suitable. The intention is now that the Swedish Research Council will finance this to a value of SEK 24 million.

To receive support from the In-Kind Reference Committee at ESS for this to be credited as an in-kind contribution for Sweden, the Swedish Research Council and ESS have signed a Letter of Intent describing the parties' shared intentions. The Swedish Research Council now hopes that the ESS Council, based on this document, will decide to credit Sweden with the first of its kind contribution to the ESS at the next meeting in December.
