Product Details

MAxes ^TMsystems provide variable magnetic field on the three principal axes and are particularly useful for orientation studies on a variety of samples. The system is comprised of a 2 or 3-axis superconducting magnet, low helium consumption current leads, magnet dewar and other associated electronics. Typical specifications include magnetic fields up to 9T for the principal vertical axis, 2.0/3.0 inch vertical clear bore and up to 3T rotating vector using any combination of x, y and z-axis magnets. It is possible to use the magnet system with existing sample inserts or AMI can provide a variable temperature insert which operates from 1.5K to 300K. Our users have also used such systems with 3rd party He3 systems and dilution refrigerators.

The MAxes ^TMsystem provides a unique way to rotate the magnetic field vector on the three principal axes and this has proved useful in performing anisotropic studies on a variety of materials. MAxes ^TMsystems have also been very useful in advancing research in the areas of spin based physics.

The magnet system software provides automatic sequencing of power supply currents and thus magnetic fields that allow the user to specify and control the magnetic field vector from a single computer screen (below). The interface allows the user to enter the desired field vector of a 3-axis magnet in Cartesian, cylindrical, or spherical coordinates. Cryogen Free (CF- MAxes ^TM) and Optical Access (Opti-MAxes ^TM) systems are also available.

Customers are finding the combination of a Dilution Refrigerator with a MAxes ^TMsystem useful in the study of Quantum Mechanics and other nanoscale studies.

Company Details

The rated field of each AMI magnet is the field at which the magnet can be operated continuously when immersed in liquid helium at a maximum temperature of 4.2K. Quench fields exceed the rated field in all cases. All standard magnets are tested by AMI in excess of the rated field. Warranted performance at lower temperatures and higher fields can be supplied on special order. Protection from damage in the event of a quench at fields up to and including the rated field is assured by the design and construction of the magnet. Each magnet is warranted against such damage by the standard AMI warranty.
All quoted currents are nominal and may vary slightly from the cited currents in the final magnet. The coil constant which specifies the magnetic field produced per ampere of current is supplied with each magnet. This constant is determined analytically for lower-homogeneity magnets, or by NMR measurements for high-homogeneity magnets.
Persistence of the magnetic field in the persistent mode varies with the inductance of the magnet and the conductor used in its construction. Guaranteed quotations can be provided upon request.
Homogeneities are specified as the maximum deviation from the central field at any point in the specified volume, and are usually quoted over a 1 cm diameter spherical volume. Where required, the homogeneity is verified using a 3 mm diameter NMR probe moved throughout the homogeneous volume.
