Design Consultancy
Our principal design staff are available to help solve engineering problems in the fields of cryogenics and superconductivity.
Stephen Harrison
MA (Cantab) CEng FIMechE MInstP
Stephen Harrison graduated from Cambridge University in 1990 with a triple first class degree in Engineering: he was one of the founders of Space Cryomagnetics Ltd in 2000. He is responsible for all cryogenic engineering in the company, including the zero-gravity superfluid helium system for the AMS-02 superconducting magnet, and the cryogen-free cooling systems for HTS magnets. He is also the project leader for the AMS-02 superconducting magnet, which is to be used on the International Space Station for the detection of anti-matter and dark matter as well as cosmic ray research.
Stephen has designed the cryogenic systems for many large and complicated magnet projects, including both the CLAS torus and the KLOE solenoid - two of the largest superconducting magnets ever built. He was also project leader for the design and manufacture of the HADES torus magnet at GSI in Germany, a six-coil torus with a diameter of 4 m. After designing a range of highly efficient, vapour-cooled current leads installed at CERN and elsewhere, Stephen was the project leader for a collaboration with CERN to develop 12.5 kA HTS current leads for the new LHC accelerator. As a result, he designed the world's first successful HTS current lead capable of operating at 13 kA.
Steve Milward
BSc PhD CPhys MInstP
Steve Milward was a co-founder of Space Cryomagnetics Ltd in 2000. He is responsible for all aspects of electro-magnetic and quench design for our magnet systems.
Steve spent four years at Leicester University researching XUV instrumentation for the ROSAT Wide Field Camera all sky survey satellite experiment. Steve then specialised in superconductivity, and was instrumental in the development of the HELIOS compact synchrotron and in the design and manufacture of a set of large, superconducting cold-iron quadrupole magnets for the Thomas Jefferson National Accelerator Facility in the USA. Later, Steve was responsible for model dipole development for the new LHC accelerator in collaboration with CERN.
Renuka Rajput-Ghoshal
MSc PhD CPhys CSci MInstP
Renuka joined Space Cryomagnetics in July 2004 to design superconducting magnet systems and to develop persistent joint and switch technology. She is also responsible for design, cost and testing of standard and custom magnet systems.
Renuka received her Ph.D. in high temperature superconductivity from Jawaharlal Nehru University, New Delhi, India. Then she worked for two years at the National Physical Laboratory, New Delhi, designing India's first NMR magnet system. She then spent six years as Scientific Officer at the Centre for Advanced Technology (CAT) Indore, with the Indian Department of Atomic Energy. At CAT, she designed the gradient coils and quench protection system for India's first MRI magnet. She also designed a 5 T wiggler magnet, a 1.5 T electromagnetic dipole magnet, corrector magnet, quadrupole magnet, ALPHA magnet and energy analyzer dipole magnets for synchrotrons and accelerators. Renuka has also worked for over 3 years on NMR superconducting magnets, mainly on process improvement for quench reduction, during which she developed a tool for conductor sensitivity analysis.
Nick Shaw
MA (Cantab) MSci PhD MInstP
Nick Shaw graduated with a first class degree in Natural Sciences from Cambridge University in 1999. Always keen to apply academic ideas to industrial applications, he was a founding member of the Medical Physics Group at the Cavendish Laboratory. During his postgraduate degree, Nick wrote a suite of software in C and C++ for the design and optimisation of novel magnets for magnetic resonance imaging using genetic algorithms.
Experienced in parallel programming on cluster computers and supercomputers, Nick designed and commissioned, in collaboration with industry, a unique 1 T 360 mm bore split-coil geometry MRI magnet. After the conferral of his doctorate in 2003, Nick took on the advanced instrument development, construction and testing of the world's first high resolution, multi-slice simultaneous combined magnetic resonance and positron emission tomography imaging system.
Nick joined Space Cryomagnetics Ltd in 2005.
Mark Gallilee
MEng CEng MIMechE
Mark Gallilee joined Space Cryomagnetics Ltd in January 2005 as a Project Engineer. He is responsible for design and mechanical analysis of magnet systems and sub-systems. Mark has successfully qualified a number of special components - including persistent switches - for use in manned space flight. As well as his design and analysis expertise, he is experienced in the latest manufacturing techniques and methodologies.
Mark has a first class masters degree in engineering from Durham University
Robin Stafford Allen
BSc MSc CEng FIMechE MCMI
Robin Stafford Allen joined Space Cryomagnetics Ltd in March 2003. He is responsible for the mechanical engineering aspects of all products made by the company including the AMS-02 superconducting magnet.
Robin has worked with superconducting magnets since 1982. He joined Oxford Magnet Technology (OMT) to make Whole-Body scanner resistive and superconducting magnets. Robin led the mechanical engineering group at OMT, and managed their entry into the truck-mounted superconducting magnet for mobile scanning clinics.
For ten years Robin worked on the JET Nuclear Fusion project based at Culham, leading the group developing cryogenics systems for heating and fuelling the plasma, and managing the large helium and nitrogen cryogenics facility associated with this multi-national experiment.
George Tvalashvili
MSc PhD
George received his Ph.D. in Low Temperature Physics and Cryogenic Techniques from Kapitza Institute for Physical Problems, Moscow, USSR. Then he worked three years as a postdoc for Prof. F. Pobell at Bayreuth University, Germany. Main activities for that time were: feasibility of possible experiments on He-6, building large nuclear demagnetisation cryostat for investigation of materials at ultra low temperatures, well below 1 mK. After three years work at Bayreuth University, George moved to the Low Temperature Laboratory at the Helsinki University of Technology (Prof. O. Lounasmaa, Prof. M. Paalanen), where he joined the group which was carrying out optical investigation of solid He-4 and He-3 at ultra low temperatures.
After completing the work at Helsinki, George joined Prof G. Pickett's group at the School of Physics and Chemistry, Lancaster University. This time he was investigating very diluted He-4/He-3 mixtures (< 0.1% He-3) at ultra low temperatures using NMR and vibrating wire techniques. Since leaving Lancaster, George has worked as a cryogenic engineer on the development, design and test of long hold helium cryostats for NMR magnets, UHV systems, and ultra low temperature cryostats.
George joined Scientific Magnetics in 2007.
