VACUUMSCHMELZE Delivers Undulator
Magnet Assemblies to Lawrence Berkeley
National Laboratories for Development of
Advanced X-Ray Laser

VACUUMSCHMELZE GmbH & Co. KG (VAC), a global manufacture
of advanced magnetic materials, and Lawrence Berkeley National
Laboratory (LBNL) have partnered to develop a new magnet design
assembly that will be used in undulators for a next-generation free
electron laser (FEL) under development by the Stanford Linear Accelerator Center (SLAC).
SLAC is currently developing its next-generation FEL as part of
its LCLS-II (Linac Coherent Light Source) project, which will significantly enhance X-ray capabilities and will enable more advanced
research in energy, healthcare and technology. The VAC modular
assemblies are an integral part of FELs and are used in hard and soft
X-ray undulators.VAC and LBNL's new jointly-developed magnet
design assembly, containing VAC's new VACODYM 956 DTP material and its VACOFLUX 50 parts, enables extremely narrow required
magnetic and mechanical tolerances. These tolerances define the
quality of the undulator systems, and ultimately the FEL.
Additionally, the partnership of VAC and Lawrence Berkeley
represents an important milestone for VAC Americas as it establishes a deepened presence within the North American market
and provides a technology solution that can be relied upon in
critical applications.
"We are very pleased that LCLS-II in the USA is now using our
magnets and magnet systems. In addition to several other major
FEL projects, including the European XFEL in Germany, the Swiss FEL
in Switzerland, and the PAL FEL in Korea, this is the fourth largescale project that uses our materials. These research facilities nearly

cover the complete Free Electron Laser energy spectrum," said Dr.
Ralf Koch, head of Research & Development at VAC. Dr. Koch added, "VAC's broader range of VACODYM and VACOFLUX solutions
can be used in additional applications including automotive sensors, MRI systems, beam guiding systems and electronic measuring
instruments, among others."
Beyond using VAC-LBNL undulators at its own facility, LBNL is
starting to provide these undulators to other institutions that research FELs. To these institutions, LBNL will be able to highlight
its relationship with SLAC that is financed, inter alia, by the U.S.
Department of Energy, and that now uses the VAC-LBNL undulators
in its LCLS-II particle accelerator project, which is planned to be
activated in 2019.

Global Permanent Magnets Market Share, Size,
Trends And Growth Rate From 2017 To 2022

Permanent magnet is an object which is made by processing ferromagnetic materials in a powerful magnetic field. One of its distinctive attributes is its high degree of retentivity which enables it
to retain magnetism so as to maintain a large magnetic flow even in
the absence of an applied magnetizing field.
Moreover, as compared to other energy storage devices, permanent magnet does not perform any network on its surroundings
due to which its performance is not affected by repeated usage.
Owing to the aforementioned characteristics, it finds numerous applications across various industries.
