American-magnetics MAxes Multi-Axis Magnet systems for Vector Fields Manuel d'utilisateur télécharger pdf (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

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

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.

Opti-MAxes

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.
