Instruments has received an order for state-of-the-art high
field magnet from Diamond Light Source for ultra high vacuum
experiments. This order is for a 14 T split pair superconducting
magnet, which will provide a high magnetic and low temperature
(<1.5 K) sample environment during experiments when a sample
will be exposed to an x-ray beam under ultra high vacuum. It will
be used on the new I10 Beamline for Advanced Dichroism Experiments
(BLADE) at Diamond Light Source (Oxfordshire, UK) and dedicated to
soft x-ray magnetic spectroscopy.

To allow fast ramping of the magnetic field, this magnet will be
constructed using Oxford Instruments' innovative Nb3Sn
superconducting wire, developed as part of its contract to supply
58 tonnes of wire to the ITER project. It will also be fitted with
a recondensing cryostat which considerably decreases the liquid
helium consumption of such powerful superconducting magnets while
enabling stringent magnet designs. Recondensing technology uses a
cryocooler to capture evaporated gas and turn it back into liquid
helium.
Last year Oxford Instruments supplied the ISIS neutron source,
situated on the same site as Diamond, with two high field split
pair magnets fitted with these recondensing systems- a 9 T
wide-angle and a 14 T at 4.2 K.
The Diamond BLADE magnet will also be of very clean construction
as it will work in a ultra high vacuum (UHV) environment, building
on capabilities, processes and facilities which Oxford Instruments
has developed over the last two years to allow the cleanest
construction of magnets and ultra low temperature inserts.
John Burgoyne, Manager of the Magnets Business Group at Oxford
Instruments says: "Working with customers at the leading edge of
science and technology such as Diamond Light Source, the ISIS
neutron source and many other world-leading research institutes and
facilities whose requirements constantly drive and challenge our
own technology development, continuously enhances our expertise in
advanced superconducting magnet systems. In particular we are
pleased to be able to build upon our strengths in high field
recondensing magnet systems for beamline applications with this
order.
We are delighted to have this opportunity to work closely with
the Diamond team and to be a part of the UK and local economy which
both supports and benefits from this world-class science base in
the UK".
