Space Cryomagnetics Ltd obtains ISO 9001:2000 certification
We have achieved the international quality assurance standards for ISO 9001:2000 certification.
July 2004
AMS Magnet Coil Testing Completed
In June and July 2004 the last two AMS coils were successfully tested. These are the two large coils which provide the majority of the magnetic field perpendicular to the axis of the detector. All fourteen coils have now been successfully operated at 1.8 K: they are now being assembled into the flight configuration for testing.

Order Received for a Second ADR Magnet for Space
Space Cryomagnetics has received a second order from the Mullard Space Science Laboratory for an ADR magnet for use in space, as part of the ESA XEUS programme.

Space Cryomagnetics Ltd Receives Another Order for HTS Magnets
In late December 2003, we received another order for a HTS magnets for an ion source. This latest magnet will be larger than the previous system.
December 2003
Successful Testing of AMS Magnet Coils
All twelve of the flux return coils of the AMS magnet have now been tested. The two (larger) dipole field coils are in the final stages of manufacture and should be tested in 2004.
September 2003
Successful Completion of HTS Magnet System
We have now completed installation and testing of an HTS magnet system consisting of two solenoids operating at 25 K in an iron yoke. The magnets were wound from BSCCO-2223 conductor supplied by American Superconductor.
July 2003
Successful Test of HTS Magnet
Seven months after receiving the order, Space Cryomagnetics has successfully tested the first of two HTS magnets. The magnet was operated at its maximum current (without iron) of 150 A in its own cryostat at temperatures up to 25 K. Further testing will be carried out before the magnet is installed in its iron, and the second magnet is already nearing completion.
July 2003
Successful Testing of AMS Magnet Coils
Ten of the fourteen AMS coils have now been successfully tested at 1.8 K.
HTS Magnet Progress
Space Cryomagnetics has started manufacture of the HTS magnet referred to below. The magnet will generate fields up to 3.1 T at a temperature of 27 K using a single-stage cryocooler.
Space ADR Magnet Progress
Space Cryomagnetics is continuing to work with the Mullard Space Science Laboratory to design and build ADR magnets for use in space as part of the European Space Agency's XEUS programme.
Paper Accepted for Publication
"Cryogenic System for a Large Superconducting Magnet in Space" corresponding author Stephen Harrison of Space Cryomagnetics Ltd was presented and accepted for publication at the 2002 Applied Superconductivity Conference in Houston.
August 2002
HTS Magnet Design Completed
Space Cryomagnetics has completed the design of a two-coil, cryogen-free HTS magnet system. Manufacture of the magnet and associated systems is expected to begin soon.
July 2002
Progress with AMS Manufacture and Test
The first AMS flight coil (of fourteen) was successfully tested at 1.8 K in July 2002. Manufacture of the remaining flight coils is progressing well.
November 2001
Progress with AMS Cryogenics
A series of successful tests has been carried out on a cryogenic test facility for the AMS superconducting magnet. These tests proved that the novel design of the superfluid helium cooling system is suitable for cooling the magnet coils. The analysis also proved that the complicated non-linear analysis tools developed by Space Cryomagnetics Ltd for modelling the unusual thermodynamic behaviour of superfluid helium give accurate predictions.
October 2001
Current Lead Delivery
Space Cryomagnetics Ltd has shipped two pairs of 1200 ampere current leads to CERN. The leads were specially designed to fit into an existing cryostat. From receipt of order to shipping from our facility at Culham took just 9 weeks.
September 2001
ADR Magnet Delivered
An adiabatic demagnetisation refrigerator magnet was delivered by Space Cryomagnetics Ltd to the Mullard Space Science Centre in September 2001.

Paper Accepted for Publication
"Loss of Vacuum Experiments on a Superfluid Helium Vessel" by Stephen Harrison of Space Cryomagnetics Ltd was presented at the 17th International Magnet Technology Conference in Geneva in September 2001. The paper has been accepted for publication without amendment following peer review.
