Title: Cryogenic Technology from STFC


1
Cryogenic Technology from STFC www.cryox.co.uk
2
Cryox Ltd was formed in 2007 to provide a
commercial face for cryogenic technology from the
three main laboratories operated by STFC the
Science Technology Facilities Council one of 7
Research Councils operated by the UK Government
3
The Rutherford Appleton Laboratory in Oxfordshire
was founded in 1957. It is home to the ISIS
neutron source the new Diamond synchrotron. It
has a substantial Space Science Group, and a
world-class Laser facility. A number of
presentations from Dr Tom Bradshaw, Head of the
Cryogenics Group at Rutherford Appleton are
included in the downloads available on the Cryox
website to illustrate the technology and
expertise available from the Lab
4
ALMA The Atacama Large Millimetre Array.
Cryostats are being made at RAL for the 66
100-ton antennae to be located 5000m above sea
level in the Atacama Desert. Each cryostat
houses 10 receivers mounted on quick-release
cartridges cooled to 4K. ALMA represents the
largest assembly of superconducting electronics
ever built, and will allow astronomers to observe
cold regions of the universe with unprecedented
clarity
5
PLANCK The Planck Space Mission, due for launch
in 2008, will provide a map of the Cosmic
Microwave Background to new levels of
sensitivity, helping to answer questions of how
galaxies, stars, planets and indeed the universe
are formed and evolve. Planck has an extremely
complex cooling chain including a 4K long-life
cryocooler with Joule Thomson stage supplied by
the Rutherford Appleton Laboratory.
6
ATLAS ATLAS is a particle physics experiment at
the Large Hadron Collider at CERN. Starting later
in 2008, the ATLAS detector will search for new
discoveries in the head-on collisions of protons
of extraordinarily high energy. The Higgs Boson
is one of the particles expected to be
discovered. Rutherford Appleton has supplied the
huge ATLAS End Cap Toroids Proximity Cryogenics
7
MICE The Muon Ionisation Coolihg Experiment.
Muons (and neutrinos) are elementary particles.
MICE is a precursor to the idea of a Neutrino
Factory. MICE has three 20 litre liquid
hydrogen absorbers cryocooled to less than 20K in
a system of superconducting magnets and absorbers
designed to focus the muon beam drawn from the
ISIS particle accelerator
8
ATSR This stands for Along Track Scanning
Radiometer, a space mission made possible by the
lon-life, low vibration Stirling cryocooler
developed at Rutherford Appleton Laboratory. The
slides here illustrate the results of the ATSR
mission, starting with this night-time image of
the English Channel, showing the temperature
gradients over a range from 278 to 290K
9
Advanced Materials Engineering there is an
exceptional range of material specifically
cryogenic testing facilities at the Rutherford
Appleton Labs of a kind not found commercially -
established to support modelling and design of
superconducting magnets and the reliable launch
of cryogenic equipment in space. This capability
is complemented by an additional suite of test
equipment at the UK ATC
10
Superconducting Magnets Here the slides
illustrate the capability and experience at
Rutherford Appleton in superconducting magnet
insulation, in modelling (an expertise which has
given rise to the spinout company Vector Fields)
and in a range of magnets including a helical
undulator and large magnets supplied to
scientific facilities in Europe such as CERN
11
Daresbury Laboratory in Cheshire is home to the
biggest helium refrigerator in the UK, an element
of the large scale cryogenic systems developed to
support the Labs work on synchrotron light
sources. The Cockcroft Institute at Daresbury is
an international centre for Accelerator Science
and contains a brand new ultra-high vacuum
laboratory.
12
The UK Astronomy Technology Centre in Edinburgh
occupies a spectacular location on Blackford
Hill, overlooking Edinburgh and the Firth of
Forth. It is co-located with The Royal
Observatory which dates from . Cryogenics are
fundamental to the optics, detectors and
precision mechanisms employed in modern
astronomy, and the UK ATC has extensive cryogenic
test facilities
