Media Release, 3 August 2007
HTS-110 has shipped the first of its 5
tesla HTS Beamline magnets to the Hahn-Meitner Institute in
Berlin, Germany. It is the most powerful magnet to date from
the New Zealand company, achieving an impressive 5.4 tesla during
testing, well above the 5 tesla minimum target. The magnet is
destined for magnetic diffraction research at the Berlin Electron
Synchrotron (BESSY), Germany's advanced synchrotron radiation
facility.
Weighing less than 100kg and occupying slightly
more space than a carry on travel case, the magnet is a feat
of mechanical, cryogenic and superconducting design and engineering.
The design constraints were significant, with the magnet required
to fit within a rotating cradle to allow observation of vertical
and horizontal scattering from the 10mm diffraction slit.
A pulse tube cryo-refrigerator provides quiet,
low vibration, low maintenance cooling, while HTS-110 designed
control and monitoring electronics provide safety and power
management.
In its new facilities, the magnet will be
used by a wide variety of physicists studying resonant magnetic
scattering and high resolution diffraction on HMI's beamline
diffraction instrument "MagS".
Professor Michael Meissner, head of the sample
environment group at HMI, is excited about the addition of the
high performance magnet to their advanced facility. "The HTS-110
cryomagnet has been designed to adopt a 3-stage closed cycle
refrigerator (CCR) that allows rotation of the sample in the
field. This kind of unique set-up marks a milestone in cryogen-free
sample environment systems for beamline condensed matter research,
allowing experiments to be performed at temperatures from 0.6
K to 600 Kelvin and at magnetic fields up 5.4 tesla."
Dr Donald Pooke, CTO of HTS-110 notes that
"this is a fantastic technical achievement after a very challenging
design and fabrication process". He adds that "this has only
been possible due to the dedication of our production team and
the amazing technical resource in local engineering partners".
Dr Pooke sees beamline magnets such as these
as a significant opportunity for HTS-110. A second 5 tesla HTS
beamline magnet, for ANSTO in Australia, is shipping soon. "The
HMI beamline magnet represents a significant step forward for
HTS-110, technically and commercially. We have not only cemented
our "total solutions" strategy by supplying turn-key systems,
we can now look at magnets of 6 tesla and beyond using HTS technology,
opening up further exciting opportunities."
