2021 Prize Winners
1-Walter Hälg Prize Winner: Prof. Peter Böni
Prof. Böni has been awarded with the Walter Hälg Prize in recognition of his ground-breaking contributions in the fields of superconductivity and magnetism. His most recent work, the discovery of topological skyrmions in MnSi, has established the existence of a new state of matter of topological nature and opened an entirely new field of research with possible applications in information technologies.
In addition, his impressive scientific work is at least mirrored by the impact of his outstanding contributions to the development of novel neutron instruments and instrument components. In particular, his work on innovative neutron optics based on supermirror neutron guides stands out as it is of major importance for the international neutron scattering community. Devices designed by him are essential parts of neutron scattering instruments all over the world. Peter Böni’s work on neutron instrumentation has substantially contributed to the success of at least two major neutron facilities in Europe, notably the FRM II reactor at the Heinz Maier-Leibnitz Zentrum (MLZ) and the Swiss neutron spallation source SINQ at the Paul Scherrer Institute (PSI).
Walter Hälg, was a pioneer of reactor technology and neutron scattering in Switzerland. He was well known to the world-wide neutron scattering community not only through his numerous contributions in instrumentation and science. In 1999 Walter Hälg established the prize, which since 2019 is sponsored by SwissNeutronics AG.
2- Erwin Felix Lewy Bertaut Prize Winner: Dr. Ellen Fogh
Dr. Ellen Fogh has been awarded with the Erwin Felix Lewy Bertaut Prize in recognition of her multiple early career scientific achievements including her innovative work in the application of the highest available magnetic fields – static and pulsed – to elucidate the complex links between magnetoelectricity and field-dependent magnetic structures.
Among the works she has performed we can cite the multinational effort to study the magnetic structures and excitations of the Shastry-Sutherland antiferromagnet SrCu2(BQ3)2 at dilution fridge temperatures, high pressure (1 GPa) and high field (26T).
Dr. Fogh is a highly talented young researcher who should soon be in a position to lead her own research group. She is a role model for aspiring young women in neutron scattering. She consistently operates at a high scientific level, while managing to carefully mentor younger group members.
The Erwin Felix Lewy Bertaut prize is awarded jointly by the European Neutron Scattering Association (ENSA) and the European Crystallography Association (ECA) in memory of the scientific achievements of Erwin Felix Lewy Bertaut, a pioneer in crystallography and neutron scattering. The prize is sponsored by Mirrotron.
3- Neutron Instrumentation and Innovation Award Winner: Dr. Mads Bertelsen
In his young career, Dr. Bertelsen has already demonstrated remarkable contributions to neutron instrumentation. He has been awarded the 2021 Neutron Instrumentation and Innovation award in recognition of his innovative extensions of the Monte Carlo ray-tracing simulation software McStas, Guide_bot and Union.
His software Guide_bot, has simplified the process of adequately optimizing guides, which previously was tedious and time-consuming, and, in practice, impossible to do comprehensively.
Union, makes it possible for a user to simulate with McStas virtually any arbitrarily shaped component of an instrument or experimental setup. Hence, simulations can now be made at a level of detail which previously were considered impossible.
Both extensions have had a significant impact on the design of instrumentation and experiments, and hence the scientific impact from neutron scattering. His contribution has been pivotal for the design of the ESS instrument suite.
Neutron science relies on state-of-the-art infrastructure and therefore crucially on the numerous colleagues who invent, implement and maintain instrumentation and techniques. The Neutron Instrumentation and Innovation Award (NI&I) award was created by ENSA to recognize individuals who devote part of their career to enable science on a much broader scale than can be achieved by each researcher alone. The NI&I award is sponsored by Mirrotron.

About the Walter Hälg Prize
Walter Hälg, the pioneer of reactor technology and neutron scattering in Switzerland, passed away peacefully on December 28, 2011 at the age of 94. He was well known to the world wide neutron scattering community not only through his numerous contributions in instrumentation and science, but also by his generous sponsorship of the Walter Hälg Prize which has been awarded biennially to distinguished scientists by the European Neutron Scattering Association (ENSA) since 1999.
Born in Basel in 1917, citizen of Basel, Switzerland, he was one of the pioneers in the area of neutron science. Experimental physics, theoretical physics, chemistry, and mathematics were the four fields that took up his student time at the Basel University where in 1943 he received his PhD in molecular physics. From 1943 to 1946 he worked in particle physics at the Physical Institute of the University of Basel and on the construction of a 1 MeV Cockroft-Walton accelerator in Basel. He spent the years 1946-1960 at the Brown Boveri Company (BBC, predecessor of the current ABB) in Baden, Switzerland, and was promoted head of the physics department in 1953. During his time at BBC, he worked on the development of the Swiss heavy water reactor DIORIT at Würenlingen, which went critical on 26 August 1960. In between, i.e. 1952/1953, he was sent to the Dutch-Norwegian Reactor Research Institute JENER in Kjeller, Norway.
In 1960, he was named full Professor and director at the newly founded “Institut für Reaktortechnik IRT” at ETH Zürich, with an outstation at the EIR Würenlingen. His main fields of research focused on reactor theory, numerical mathematics, neutron diffraction, and computer science. He was involved in the construction of the neutron spectrometers at the reactor DIORIT as well as in the development of a multiprocessor computer (16 CPU’s) for solving partial differential equations. After decommissioning of the reactor DIORIT in August 1974, he carried out the first calculations for a spallation source using the surplus protons of the 590 MeV ring of the near SIN institute for neutron production, seeing the limitations for neutron scattering at the reactor SAPHIR in Würenlingen, ideas supported also by Walter E. Fischer.
Professor Hälg’s contributions to neutron scattering are extensive. He supervised many PhD students in neutron scattering, among them the A. Furrer, P. Fischer, and J. Schefer. For 10 years, he was a member and president of the Research Board of the ETH Zürich until his retirement in autumn 1984 when he became an honorary member of the executive board of the Swiss Neutron Scattering Society. He was also honorary member of the distinguished Physical Society of Zürich.
Albert Furrer continued Walter Hälg´s work as the new head of the Laboratory for Neutron Scattering. In 1996, the neutron scattering activities were moved from the reactor SAPHIR to the newly built continuous spallation neutron source SINQ at the Paul Scherrer Institute, a merger between SIN and EIR.
Albert Furrer was acting chairman of the European Neutron Scattering Association when he proposed Professor Hälg to sponsor and to give his name to the Prize. The award is given to European scientists who have achieved an outstanding research program in neutron scattering with a long-term impact on scientific and /or technical neutron scattering applications. The scope of this prize is coincident with the result of the professional career of the man who gave his name to this prize. Walter Hälg will be remembered by many in the field not only as a pioneer in reactor technology and neutron scattering but also as a friend. His wife Madeleine Hälg-Degen continued to sponsor the highly prestigious ENSA Prize until her death in 2017. In the future it will be called the Walter and Madeleine Hälg Prize. We are pleased that SwissNeutronics AG, Klingnau, Switzerland, kindly agreed to take over the sponsorship.
