Through the LENS: foreword by Pavel Strunz
On behalf of LENS’ newest member, Pavel Strunz, Head of the Neutron Physics Laboratory at NPI, introduces the facility, its user community, and its role in coordinating the Czech Republic’s contribution to ESS.
The Nuclear Physics Institute of the Czech Academy of Sciences (NPI) is located in Řež, which is about 15 km north of Prague. The experimental base for our neutron science is mainly the Neutron Physics Laboratory at the LVR-15 nuclear reactor, operated by Research Center Řež.
The Neutron Physics Laboratory is part of the Center of Accelerators and Nuclear Analytical Methods, which provides users with experimental techniques also at our accelerators (cyclotrons, Tandetron and AMS accelerator), including radioisotope production, nuclear analytical methods and radiocarbon dating.

The academic part of the Czech neutron user community is mainly concentrated around the three largest institutions in the field – the Nuclear Physics Institute, the Institute of Physics of the Czech Academy of Sciences, and the Faculty of Mathematics and Physics, Charles University. Of course, a large number of neutron users also come from other academic institutions and our industrial partners. The Czech user community is largely focused on solving problems in the study and development of advanced materials, and our Neutron Physics Laboratory is also methodologically oriented the same way.
The Neutron Physics Laboratory offers seven instruments on the horizontal reactor channels and a special experimental method on the vertical channels (neutron activation analysis – NAA). Our experimental stations are in some cases unique and complementary to those available in other European labs (e.g. high-resolution SANS, high-resolution materials science diffractometer, Neutron Depth Profiling). Besides the reactor, fast neutron facilities are also available at our cyclotrons U-120M and TR-24. Quasi-monoenergetic generator of fast neutrons based on 7Li(p,n) reaction as well as variable-energy broad-spectrum neutron generators with Be target can be used for investigation of radiation hardness of electronic components or neutron cross-section measurements of materials intended e.g. for the first wall of future fusion reactor.
The focus on materials science also logically influenced the form of NPI’s involvement in the construction of the ESS at Lund. In addition to a number of target technology deliveries, the scientific part of the in-kind contribution of the Czech Republic, which NPI has the honour to coordinate, is the development, manufacture and installation of the BEER neutron diffractometer (Beamline for European Materials Engineering Research), on which we are working closely with Helmholtz-Zentrum Hereon in Geesthacht. Putting the BEER diffractometer into routine operation is a major challenge for us. We firmly believe it will bring substantial scientific progress in our field and significantly strengthen our collaboration with the European partners.

Science Highlight
Secrets of a silky cotton shirt
Neutron fibre diffraction experiments at ILL throw light on mercerisation – an important manufacturing process in the textile industry.
Industry Highlight
A team from Audi Sport joined forces with the Advanced Materials Group within the Laboratory for Neutron Scattering and Imaging at SINQ (PSI), and technology transfer centre, ANAXAM, to examine a brake caliper in action using neutron imaging. The analyses revealed ways to optimise the movement of the brake pistons to reduce a vehicle’s carbon footprint.

Pavel Strunz - Head of Neutron Physics Department at NPI
Pavel Strunz commenced his professional career in neutron physics in 1989 as a PhD student in Nuclear Physics Institute of the Czech Academy of Sciences. He carried out experiments predominantly at LVR-15 research reactor in Řež, but also at Salaspils near Riga (Latvia) reactor and at BRR reactor of Budapest Neutron Centre, Hungary. He then became a postdoc, and in 1988 he started at Hahn-Meitner Institute (presently Helmholz Zentrum Berlin), Germany, at BER-II reactor where he focused on Small-Angle Neutron Scattering investigation of high temperature materials. In connection with this research topic, he developed software for evaluation of anisotropic SANS data.
In the period 2002-2004, Pavel Strunz continued with materials research topics, particularly Ni-base superalloys and Co-Re alloys, as the instrument scientist of SANS-II device of SINQ neutron scattering center, Paul-Scherrer Institut Villigen, Switzerland. Starting from 2004, he employed neutron diffraction as the instrument scientist of MAUD diffractometer of Neutron Physics Laboratory (NPL) in NPI Řež, Czech Republic. Pavel Strunz also carried out a number of user experiments at MLZ Garching. In parallel, he coordinated the open access of the user to NPL within NMI3 consortium project.
Since then, he has been actively involved in European collaborations in neutron physics. In 2012, Pavel Strunz became the head of Neutron Physics Department of NPI Řež. His scientific focus is investigation of metals and composites (e.g. Co-Re alloys, Ti alloys, W alloys, Cu-Al composites, metals after severe plastic deformation) by using neutron diffraction.
