Summary

SPECIMENS CAN BE STUDIED AT ANY CONTROLLED TEMPERATURE BETWEEN 1.4 AND 300 K AND IN ANY SELECTED SYMMETRIC HORIZONTAL FIELD BETWEEN 0 AND 3 T IN THE SAMPLE VOLUME. THE UNIQUE FEATURE OF THE CRYOSTAT ISTHAT IT PERMITS ALMOST 360 DEG ACCESS FOR A NEUTRON BEAM INCIDENT ON THE SPECIMEN. THE MAGNETS MAY BE RUN IN ASYMMETRIC MODE TO PULL THE FIELD NODES OUT OF THE SCATTERING PLANE SO AS TO AVOID DEPOLARIZATION OF THE NEUTRON BEAM. A DRIVE ASSEMBLY ATTACHED TO THE TOP FLANGE OF THE CRYOSTAT HAS BEEN DESIGNED THAT POSITIONS THE SPECIMEN TO AN ACCURACY OF MORE OR LESS 0.01 DEG, EVEN IN THE PRESENCE OF A MAGNETIC TORQUE ON THE SPECIMEN.
