American Magnetics MAxes Multi-Axis Magnet systems for Vector Fields - Manual (Page 4)

Typical VTI based liquid helium cooled MX-3 systems have specifications similar to the ones listed for two axis
geometries. There are numerous benefits from cooling large magnets with liquid Helium. Most customers prefer
fast ramping of various coils and desire very low levels of vibration. Near Zero He Boil off recondensing style
systems offers such benefits. A ReCon MAxes
TM
with VTI or other inserts are one of the most desired options by
our users. Our standard product offerings includes such a system wherein a MAxes
TM
magnet is mounted in
ReCon style dewar and He gas from the VTI or the insert is cycled back into the Dewar using an oil free or “dry”
scroll pump. Any loss of LHe is easily compensated for by the introduction of gaseous Helium.

systems provide variable magnetic field on two or
three principal axes and optical access in two orthogonal planes. These
are particularly useful for orientation studies on a variety of samples
for optical & beam line applications. In light of the growing interest in
spin-related phenomena and new generation devices for processing
information, there is now renewed interest in the science and
engineering of magnetic semiconductors. Magneto-optic studies
provides an ideal means for studying properties of magnetic
semiconductors and other materials where spin related phenomena are
of paramount importance. The system is comprised of a 2 or 3-axis
superconducting magnet, low helium consumption current leads,
magnet Dewar, optical windows, and associated electronics. Typical
specifications include magnetic fields up to 4T for the principal
vertical axis, 1T rotating vector using any combination of x, y and z-
axis magnets. These are typically offered for 1.0” OD sample tube.
Systems with re-entrant bore tubes are also supplied. Wide varieties of
combinations are possible. The system is supplied with a variable
temperature insert which operates from <2K to 300K.
These are also
available in ReCon style NZHB system.
